In prior embodiment, bicycle disk brake rotor 212 is chemically treated also to include region, surface 230, and this region, surface 230 forms protection zone by diffusion technique in base rotor plate 221.Generally, region, surface 230 is alloy district or the floor with uniform thickness, and it is chemically formed on all exposed surfaces of base rotor plate 221.The thickness in region, surface 230 experiences the time span of diffusion technique according to bicycle disk brake rotor 212 and changes.By in Composite Permeability at least the first and second substrate surface 221a and 221b.Also with diffusion technique, at least one or both in periphery 222a and 222b of base portion 222 also are able to have diffusion region.In the prior art, the diffusion region in region, surface 230 can include aluminium and iron complexes.In this example, aluminium diffuses through iron and arrives the first and second substrate surface 221a and 221b thus form alloy.The concentration gradient of aluminium reduces towards base portion 222 from outer surface 230a and 230b, so that the concentration of aluminium is maximum at outer surface 230a and 230b of the directly Brake pad of contact bicycle disk brake caliper.Therefore, the diffusion region covering the region, surface 230 on the base portion 222 of base rotor plate 221 is that bicycle disk brake rotor 212 provides structural strength and corrosion resistance, particularly in the region that bicycle disk brake rotor 212 contacts with the Brake pad of bicycle disk brake caliper.
With reference to Fig. 3, it is shown that the amplification partial sectional view of a part for the external member 12 of the exemplary self car disc brake rotor 10 cut open according to the dotted line A-A' along Fig. 1 of the open embodiment of the present invention one.The bicycle disk brake rotor with pivot axis includes base portion 22 and surface element 23.The base portion 22 of base rotor plate 18 comprises iron and has outer peripheral edge 22a and inner peripheral 22b.Intermediate member extends radially inwardly from the inner peripheral 22b of base portion 22.Base rotor plate 18 has first and second substrate surface 21a and 21b in the opposite shaft orientation direction towards bicycle disk brake rotor 10.First and second substrate surface 21a and 21b are the flat surfaces extended on base portion 22, intermediate member and wheel hub attachment members.First and second surface 21a and 21b can be all smooth on all regions.Such as, the first and second substrate surface 21a and 21b can be waveform in the region of intermediate member and wheel hub attachment members.
Bicycle disk brake rotor 10 is chemically treated also to include surface element 23, and this surface element 23 forms protection zone by diffusion technique on the outer surface of base portion 22.In certain embodiments, through hole 20 can also have the side face forming surface element 23 completely, and this surface element 23 includes the protection zone formed on the outer surface of base portion 22 by diffusion technique.In the present embodiment, surface element 23 is alloy district or the floor with uniform thickness, and it is chemically formed in all exposed surfaces of base rotor plate 18.It is however not limited to this embodiment, other embodiments can comprise the surface element 23 in the finite region of the exposed surface being chemically made only in base rotor plate 18.
Surface element 23 includes concentration gradient and diffusion region, this diffusion region has the composite comprising iron, aluminium and chromium being spread and penetrating at least the first and second substrate surface 21a and 21b, and it follows the concentration gradient of the chromium along the axial direction parallel with the pivot axis of bicycle disk brake rotor device 10 and aluminium.The concentration gradient of chromium reduces towards base portion from the outmost surface of surface element 23 so that realize the Cmax of chromium on outmost surface that is first and second outer surface 30a and 30b, and realizes the Cmin of chromium at the penetralia of surface element.Because the first and second outer surface 30a and 30b achieve the Cmax of chromium, so providing structural strength and corrosion resistance for bicycle type brake rotor 10, particularly in the region that bicycle disk brake rotor 10 contacts with the Brake pad of bicycle disk brake caliper.
At least one or both in periphery 22a and 22b of base portion 22 also are able to have diffusion region.In this example, aluminium and chromium are diffused into the first and second substrate surface 21a and 21b thus form alloy.The alloy being made up of iron, aluminium and chromium stated is better than the alloy being only made up of iron and aluminium, this is because the alloy stated and quenching hardening have been implemented in combination with corrosion resistance, wearability and the structural strength improved, so that the Vickers hardness of surface element (Hv) is more than or equal to 250, or less than or equal to 1000.
With reference to Fig. 4, it is shown that form the manufacturing step of the bicycle disk brake rotor of embodiments of the invention.Manufacture bicycle disk brake rotor and include four steps: (S1) compacting, (S2) diffusion, (S3) quenching are ground with (S4).In step S1, when iron strikes out the intended shape corresponding to external member, pressing process is utilized to form disc brake rotor.Because the hard to bear porous to base matrix of corrosion resisting property, hardness and surface finish impact, so needing carefully to suppress the iron not having crackle, hole and fracture.
In step S2, diffusion technique is utilized to form surface element.In diffusion technique, by heating at about 900-1000 DEG C in rich in (solid, liquid or gas) medium of chromium and aluminium, and make chromium and aluminium be diffused in iron, thus realize hardness, structural strength, wearability and corrosion resistance.The thickness of control table face is carried out by the diffusion time during regulation diffusion technique and medium temperature.The temperature of medium is kept within the above range, may infringement quenching hardening process subsequently because exceeding temperature upper limit.
In step S3, the surface element of disc brake rotor is carried out quenching hardening.In quenching hardening process, heated metal is cooled down rapidly, thus prevents the formation of whole crystal structure, thus produce firm in structure and the amorphous metal of shatter-resistant, thus realize toughness and the ductility of height.Successfully process and need heated metal cool down immediately after diffusion technique completes and be quenched with maximum possible speed.When the process of implementation success, it is possible to use various hardening medias (such as water, oil, polymer or forced ventilation).Need to be carefully controlled Quenching Treatment to be formed without internal stress in cooled metal.In certain embodiments, the manufacturing process of disc brake rotor can skip quenching hardening process to reduce manufacturing time and cost.In other embodiments, disc brake rotor can experience diffusion technique and quenching hardening for twice to implement tempering.
In step S4, grinding technics is utilized to form the outmost surface of surface element.Mating the size of disk brake system without the chromium of excessive loss surface element and aluminium content by starting from surface to grind away a part for surface element, grinding technics (optional step strictly speaking) achieves the expectation thickness of surface element.In certain embodiments, the thickness of surface element can be preferably more than 10 μm, more preferably larger than 50 μm, and most preferably more than 70 μm.In other embodiments, can calibrate manufacturing process as follows, the most unnecessary technique that is ground is to adjust the size of bicycle disk rotor to mate disk brake system.
As shown in Figure 5A, the chromium concn in the surface element at any set point depends on the distance of its distance outmost surface.Here, the relation between the chromium concn in the surface element at any set point, its distance and time quantum of diffusion technique away from outmost surface is depicted at about 900 DEG C for the situation when iron is heated to 900 DEG C in rich in (solid, liquid or gas) medium of chromium and aluminium.For each diffusion profile, the chromium concn in surface element increases along with the distance away from outmost surface and declines.The diffusion time increased allows chromium and aluminium to have the longer time to diffuse through surface element, thus adds the chromium concn spreading all over whole surface element, and allows chromium and aluminium to be deeper penetrated in iron, adds the thickness of surface element the most in process.But, the concentration of iron in the outmost surface of surface element can be caused long diffusion time too low, thus cause surface element to lose some characteristics that iron provides, such as excellent thermal diffusivity.Therefore, diffusion technique should be ideally achieved the balance of final ratio of the iron in surface element, chromium and aluminium.
As shown in Figure 5 B, the chromium concn in the surface element at any set point depends on the distance of its distance outmost surface.Here, the relation between the chromium concn in the surface element at any set point, its distance and time quantum of diffusion technique away from outmost surface is depicted at about 1000 DEG C for the situation when iron is heated to 1000 DEG C in rich in (solid, liquid or gas) medium of chromium and aluminium.Relatively imply that compared to 900 DEG C between Fig. 5 A and Fig. 5 B, preferably iron is heated to 1000 DEG C and improves the chromium concn spreading all over whole surface element.With compared with the iron situation when being heated to 900 DEG C in the medium rich in chromium and aluminium, diffusion profile also shows and declines more slowly.Therefore, data imply that compared to 900 DEG C, be diffused technique and produce chromium concn more consistent near outmost surface at 1000 DEG C.When outmost surface experience grinding technics is to realize the expectation thickness of surface element to mate the size of disk brake system, this is especially advantageous.
By also adding chromium to the outer surface of bicycle disk brake rotor in addition to aluminium, above-described embodiment improves the corrosion resistance of the bicycle rotor being made up of iron.As further advantage according to embodiments of the present invention, enhance structural strength and the hardness of the outer surface of bicycle disk brake rotor.Result improves wear resistance.
