Abstract
The utility model relates to a ball mill lining plate with a wear resistance coating layer, which is characterized in that the thickness of the wear resistance coating layer is between 2 and 5 mm. The ball mill lining plate of the utility model has high wear resistance performance, the service life is long, and the cost is low.
Description
Technical field
The present invention relates to a kind of ball grinding machine lining board, belong to powder metallurgical technology with wear-resistant coating.
Background technology
Material is one of material base of human survival and development.Current society the loss that reduces material as a very important problem.The inefficacy great majority of machine components are from the surface, and the surface strength of material directly influences the service life of machine components.According to incompletely statistics, the economic loss that causes because of fretting wear in all kinds of component of machine in whole world every year is up to hundreds billion of dollars.Because fretting wear occurs in material surface, therefore adopt advanced sufacing, preparing required wear-resistant coating in the design of common material surface optimization is a kind of simple and effective method.It not only can significantly improve reliability of products and service life, reduces the maintenance and the replacing of product, and the economical with materials and the energy, helps environmental protection, is one of developing direction of material science.
The coating of strengthening acquisition such as the material surface that makes steel high abrasion ability by surface metallurgic is raising part service life, the important means of saving steel and valuable alloy material.Therefore, in the last few years the material surface new technology particularly the development of coating technology is more and more fast.
At present, research mainly concentrates on the wear-and corrosion-resistant coatings such as Ni base that technology such as thermal spraying, plasma spraying, detonation flame spraying or laser cladding obtain, Co base, Fe base, but on technology its limitation is arranged all, poor as hot surfacing coating process, coating quality is low; Laser cladding device therefor costliness, laser power is little; Plasma spraying, detonation flame spraying noise pollution, the equipment complexity, manufacturability instability etc., thereby, in using, engineering is subjected to certain restriction.Therefore, adopt a kind of new method to prepare the extensive attention that wear-resisting corrosion-resistant coating has obtained people.
The vacuum fusion sintering technology is to utilize liquid solder alloy wetting on parent metal and sprawl and form a kind of technology with property coating at matrix surface.The vacuum fusion sintering legal system is equipped with coating, then be a kind of use vacuum fusion sintering equipment, under vacuum condition, to being coated on the alloy coat heating of piece surface, make alloy coating material generation fusion, and and matrix material between physical-chemical reactions such as dissolving and diffusion take place, promptly obtain having the face coat technology of premium properties such as wear-resisting, against corrosion and high temperature resistant with the method for surface metallurgic.The gap that in alloy powder, can add simple metal, high rigidity mutually and other nonmetallic ceramics powder etc. improve the performance of coating.
Over past ten years, its research report focus mostly on to the microstructure of Ni-based, cobalt-based, iron-based pricker coating layer and interface in conjunction with Study on Mechanism, the preparation coating is the multiselect self-fluxing alloyed powder also.Self-melting alloy is the widely used coating material with good wear-resisting erosion resistance performance of a class, be characterized in by adding a spot of B, Si element, on the one hand alloy melting point is reduced significantly, when remelting, have good mobile and from deoxidation slag making performance, thereby can obtain compact crystallization, combine good high-strength coating with base material, and have good decay resistance; On the other hand, in coating, form the boride phase of the high rigidity such as NiB, CrB of disperse distribution, make coating have good abrasion resistance.In addition, in coating, add hard phases such as WC or TiC, can largely improve the abrasion property energy, thereby reach higher condition of work, in productive life, very big using value and meaning are arranged.
Though prior art is mixed Ni-based or iron-based self-fluxing powder after vacuum-sintering prepares wear-resistant coating with WC or TiC, its sintering temperature is more than 1050 ℃, and temperature is too high unfavorable to substrate performance.And vacuum-sintering is for the cost height of industrial-scale production.
Existing ball grinding machine lining board is whole to use the steel casting preferably of potassium steel or other image height chrome cast iron uniform wearability to form, but service life is still not long, has strengthened enterprise's production cost.
Summary of the invention
The present invention proposes a kind of ball grinding machine lining board with wear-resistant coating, is used to overcome above deficiency.
The ball grinding machine lining board that the present invention has wear-resistant coating is characterised in that: the thickness of wear-resistant coating is 2～5mm.
Ball grinding machine lining board of the present invention is to form by the PM technique sintering, has coating and steel part bond strength height, wear-resisting hard phase hardness height in the coating, wearability height, advantages such as long service life.
Ball grinding machine lining board of the present invention can also reduce original casting potassium steel thickness, thereby whole ball mill deadweight is reduced, and reduces ball mill and rotates required electric power.Therefore, can reduce production costs significantly.
