instruction of china laser pointer

Laser surface alloying metal surface with a laser beam and plus alloying elements melt mixed together, the rapid solidification in the original substrate surface to form a new alloy layer. Laser alloying the substrate: carbon steel, alloy steel, high-speed steel, cast iron. The main alloying elements: Cr, Ni, W, Mo, Ti, Mn, B, and V, Co. Application examples due to the presence of cracks, spalling and other issues, at a research stage. Nano-materials or nano-composite materials: such as nano WC / Ni-based self-fluxing. Different cladding Dry Friction and Wear Test results (volume wear amount mm3) [5] different cladding materials dry friction and sliding wear test results are shown in Table 2. The single beam ofchina laser pointeris as powerful as it should be.
A factory stamping dies, the material provisions of 45 steel, processing and found that after the is Q2352A steel, the original process of flame hardening, the hardness fail to meet requirements of the Q2352A steel flame hardening, laser surface alloying, the surface micro-melting and increase carbon increasing chromium surface hardness> 450 the HV layer depth> 4 mm, to meet the requirements. Add a cladding material in the surface of the substrate material (using the preset method or synchronized method), the use of high-energy density laser beam so that the substrate surface thin test results [6], nickel-based self-fluxing alloy + WC clad layer of dry friction sliding wear tests The results in Table 3. Nickel-based self-fluxing alloy + WC clad layer rubber wheels slurry wear layer fused together, its was metallurgy Tim materials cladding layer formed on the substrate surface, as shown in Figure 3. The single beam of green laser pointer is very bright.
Automotive Steering Case: General Motors Company Saji Nuo (Saginaw) steering factory (1974) first quenching the laser used in industrial mass production, handling in the malleable iron shell body surface wear the most serious part of the five wide and 1 5 ~ 5 mm deep 0 25 0 35 mm hardened zone, hardness 64 HRC, the life of 104 laser surface transformation hardening (laser hardening) laser hardening metallic materials subjected to laser light exposure in the solid state photographs, the surface is rapidly heated to above the austenitizing temperature, and fast laser to stop the radiation self-quenched martensite a process. The working voltage ofchina laser pointeris the important parameter ofchina laser pointer.
The laser hardening for pearlitic gray iron, ferritic gray iron, ductile iron, carbon steel, alloy steel, martensitic stainless steel, aluminum alloy. The finer organization of laser hardening of steel materials than the conventional heat treatment, hardness increased by 15% to 20%, significantly improved wear resistance, shown in Table 1. MM200 type wear tester, the wear resistance of the four kinds of steel laser quenching the specimen was determined and compared with the ordinary heat treatment sample. The results show that the wear resistance of laser quenching the specimen quenching and tempering at low temperature sample increased by about 50% [1] increased by 15 times than the quenching and high temperature tempering sample. Times. (5) engine block and cylinder: the United States General Motors EMD diesel engine laser heat treatment production line completed in 1978. The working voltage ofchina laser pointershould be included in the instruction ofchina laser pointer.
