This approach in some iron-based alloy surface when widely used. The requirements of the deposited film substrate is a clean, smooth surface film interface. Thin film can usually be pre-vapor deposition, vacuum sputtering, ion implantation by means of the system, and for the production of thick film presets. Can be used electroplating, spraying, rolling, diffusion (such as boronizing), pre-coated alloy powder or diaphragm and other methods. Hard particle injection at the same time method. Hard ion injection method is characterized by the same laser to melt the substrate surface while spraying people in the pool or hard alloy powder particles in order to achieve surface alloying. This kind of china laser pointer is suitable to being used for a long time.
Laser gas alloying: refers to the appropriate atmosphere (nitrogen, carburizing atmosphere, etc.), the substrate using laser heating and melting the surface of the gas through the atmosphere, the reaction with the substrate, the thickness of the surface solid than those of normal processing to obtain the thickness of the reaction is much greater. It is mainly used in the A1, Ti and its alloys and other soft alloy substrate treatment, respectively, obtained TiN, TiC or Ti (C, N) compound layer such as surface hardness of up to l 000Hv more. Convection in the molten pool, the alloying elements can quickly penetrate the deeper parts. Laser alloying layer microstructure of laser alloyed microstructure characteristics of the laser surface alloying layer of tissue is characterized by alloying tissue heterogeneity. The customer wants to know more about the normal operation of china laser pointer.
Includes three aspects: First, alloying heterogeneity within the pool, in its cross-section will be organized within the gradient; second alloy pool within the macro-organizational heterogeneity; third is covered in front of the large cyclical changes area alloying lap area. Gradient in the organization, the common characteristics of complex organizations, there are three: flat crystal - crystal-like cells - cellular dendrite - dendrite; cellular crystal - cellular dendrite - dendrite; cellular dendrite - dendrite. Laser alloying of the macro-organizational heterogeneity is in some cases low magnification macro-organization of its non-uniform, which, from a physical metallurgy point of view, the formation of macroscopic tissue heterogeneity is mainly due to laser melting the alloy under not melt pool convection in the melt of the alloy elements within his mixing, the composition of the present macro-heterogeneity. The china laser pointer factory has the strong competition ability in the market for its new technology of china laser pointer.
Laser alloying technique anti-cracking measures (omitted). Laser alloying technology. Using laser surface alloying process can be in some cheap, poor surface properties of the system out of the base metal surface wear and corrosion, high temperature alloy surface used to replace expensive overall alloy, saving precious materials and the Authority's strategic materials, so that low-cost alloy for more widely used, thus greatly reducing costs. In addition, it can also be used to create a performance with the conventional metallurgical methods fundamentally different surface alloy, for example, foreign laser surface alloying process developed superconducting alloy MoN, MoC and V3Si, the surface of the metal used to make glass FeCrCB, NiNB and so on. The presentation of china laser pointer contains the brief introduction of china laser pointer.
Laser alloying technique application in production instance is not uncommon, for example, USA and China Li Fute ordnance company uses high-power laser coating technology to improve the erosion resistance of large diameter barrel life; U.S. General Motors aluminum engine valve seat on alloying, deformation <0.13mm, hardness greater than 55HRC, at 540 ℃ under the conditions of two hours no significant softening; the former Soviet Union on the A125 aluminum alloy piston ring groove for Ni, Cr alloying, life expectancy increased 3-3.5 times; AVCO company uses 30% Cr alloy powder laser processing automobile engine exhaust valve to wear resistance, corrosion resistance and impact resistance has been greatly improved.
