The present invention is characterized in that the composite plate is composed of a thin titanium plate in the middle layer and aluminum-based solder layers, wherein the aluminum-based solder layers are arranged on the upper and the lower surfaces of the titanium plate and are combined with the titanium plate by a metallurgical mode. The aluminum-based solder comprises 0.1 to 1.0% of Cu, 0.5-2.0% of Mn and 0.2-1.0% of SiO, and the rest is Al and unavoidable impurities. The present invention simplifies soldering process, and effectively improves soldering quality. The soldering intensity can reach more than 70Mpa.
Description
A kind of aluminium-titanium-three layers of rolling composite plate of aluminium solder, aluminium-titanium-aluminium solder the rolling composite plate that relates to a kind of vacuum brazing process of the structural member that is used for titanium or titanium alloy, the true nest brazing process of the honeycomb of particularly suitable titanium and titanium alloy thereof and other complex component.
Making metal composite structure in the past, brazing process as the metallic object of honeycomb adopts lay powdery or laminar cored solder on solder side more, uses the method for powdery cored solder easily to cause the scolder skewness, phenomenons such as weldering occur leaking, operate also very complicated.And when using the sheet cored solder; because sheet cored solder processing difficulties; when carrying out brazing operation; difficulty is big; particularly the brazing process for complex-shaped multi-layer honeycomb structure is difficult to operation especially; contact with weldment because of cored solder and the problem of aspect such as scolder skewness through regular meeting, influence the effect of soldering.
The present invention is directed to the problem that exists in the prior art, provide a kind of can overcome effectively that prior art exists at hardware brazing process scolder skewness, soldering is effective, and can simplify a kind of new aluminium-titanium-three layers of rolling composite plate of aluminium solder of brazing operation greatly.
The objective of the invention is to be achieved through the following technical solutions.
A kind of aluminium-titanium-three layers of rolling composite plate of aluminium solder is characterized in that: aluminium-titanium-three layers of rolling composite plate of aluminium solder are formed with the aluminium base brazing material layer of titanium plate metallurgical binding by the Titanium thin plate in intermediate layer with on titanium plate top and bottom.
The composition of aluminium base cored solder is (percentage by weight): contain Cu:0.1%-1.0%, and Mn0.5%-2.0%, all the other are Al and unavoidable impurities for Si0.2%-1.0%.
The using method of a kind of aluminium-titanium-three layers of rolling composite plate of aluminium solder, its operation is followed successively by, titanium member of the present invention aluminium-titanium-aluminium solder three layer rolling composite plate identical with size of desiring soldering processing are stacked alternately successively, and on the upper and lower surface of stack body, exert pressure, after guaranteeing member and aluminium-titanium-three layers of rolling composite plate of aluminium solder fully contacting, put into vacuum brazing furnace and carry out soldering, brazing temperature is 660-690 ℃, temperature retention time 10-30 minute, cool off with stove then.
Because the present invention uses aluminium base cored solder+titanium+aluminium base cored solder to form aluminium titanium aluminium solder composite plate, solve conventional art and in the soldering termination process, used powdery or sheet cored solder, the scolder skewness, and the brazing operation complexity that causes thus, the unwarrantable problem of soldering effect, and aluminium-titanium-aluminium solder rolling composite plate contains aluminium base cored solder on the lower surface thereon on the one hand, Zhong Jian titanium plate can become the brazed structure intermediate course on the other hand, simplify the operating process of soldering greatly, and improved brazing quality effectively.Be specially adapted to the brazing process of multi-layer honeycomb shape structure, soldering strength reaches more than the 70MPa, has reached present requirement such as some heat exchangers of industry such as chemistry, automobile, boats and ships, vehicles fully.
Fig. 1 is a kind of aluminium-titanium of the present invention-three layers of rolling composite plate structural representation of aluminium solder.
Fig. 2 is that a kind of aluminium-titanium of the present invention-three layers of rolling composite plate of aluminium solder are used for the structure chart of brazed multilayer honeycomb body structure.
The invention will be further described below in conjunction with drawings and Examples.
A kind of aluminium-titanium of the present invention-three layers of rolling composite plate of aluminium solder, by on the Titanium thin plate 1 in intermediate layer and the titanium plate upper and lower surface by forming with the aluminium base brazing material layer 2,3 of titanium plate metallurgical binding.Can make by the method that two-layer aluminium base cored solder and the metallic titanium plate that is clipped in the middle carry out composite rolling.
The titanium member 4 (titanium corrugated plating or other shape weldment) of soldering processing will be desired, be stacked alternately successively with aluminium-titanium of the present invention-three layers of rolling composite plate 5 of aluminium solder, Gu after steady, and on the upper and lower surface of stack body, exert pressure, after guaranteeing member and aluminium-titanium-aluminium solder rolling composite plate fully contacting, put into vacuum brazing furnace and carry out soldering, vacuum brazing, furnace temperature is 660-690 ℃, constant temperature time 10-30 minute, just can finish brazing process of the present invention with the stove cooling then.
Example 1
With composition is (percentage by weight): contain Cu:0.1%-1.0%, Mn0.5%-2.0%, Si0.2%-1.0%, all the other are Al and unavoidable impurities, the aluminium base cored solder of thick 0.2mm is cut into the thin plate of 200 * 300mm, industry seal titanium plate (TA1) plate that 0.8mm is thick is cut into the tabular of 200 * 300mm equally, is levels with two aluminium base soldering flitch after cutting out, metallic titanium plate is clipped in the middle, after alignment was fixing, the four-high mill with 200 tons-300 tons carried out roughing, through an intermediate annealing, pass through finishing again, behind the leveling, be rolled down to 0.6-0.7mm again, can obtain aluminium-titanium of the present invention-three layers of rolling composite plate of aluminium solder.
Example 2
Making multilayer titanium honeycomb structured body with the brazing of titanium corrugated plating is example.
At first aluminium-titanium of the present invention-three layers of rolling composite plate of aluminium solder and titanium corrugated plating surface are carried out oil removing and surperficial alkali pickling, after the drying, aluminium-titanium-three layers of rolling composite plate of aluminium solder and titanium corrugated plating member are stacked alternately, the superiors and orlop are reinforced by clamp structure with the titanium plate, and on the upper and lower surface of stack body, exert pressure, after guaranteeing member and aluminium-titanium-three layers of rolling composite plate of aluminium solder fully contacting, put into vacuum brazing furnace, vacuumize, be warming up to 680 ℃ of temperature retention times 15 minutes.With the stove cooling, finish brazing process then, the member soldering strength is greater than 70MPa.
Example 3
Bond strength examination degree with aluminium titanium aluminium solder composite plate of the present invention soldering.
With some of the TA1 industrially pure titanium plates of 10 * 1 * 60mm size, the aluminium titanium aluminium solder composite plate of the present invention of 10 * 1 * 0.6mm is cleaned specimen surface with cleaning agent earlier, the water flushing, be placed on deoil in 10% sodium hydrate aqueous solution after, be placed on 5%HF+20%HNO
3The solution acid pickling surface, after air-dry, aluminium-titanium-aluminium solder composite plate and titanium plate are alternately put together, with titanium anchor clamps or nickel filament that its clinch is fastening, lie in then and be heated to 680 ℃ ± 5 ℃ in the vacuum brazing furnace, be incubated 15 minutes, after the stove cooling, sample carries out tension test on conventional cupping machine.Experimental result sees Table 1.
