The single beam of green laser pointer is very bright

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.
Mining slurry pump balance disc: mine-water corrosion and water erosion wear of the coal particles and the interaction of alloy steel or alloy cast iron is generally low, service life, later renamed the flame spray Ni-based alloys, parts life has improved, but the process operation is complex alloy powder consumption, deformation of the workpiece, coating defects, large parts machining. 45 steel by laser cladding Ni60 and of Ni60 + WC coating for use by the mine site, the life of flame spray Ni-base alloy coating increased by 50%, and of good quality, high efficiency [8]. (2) laser cladding pick: cladding material, Ni-based self-fluxing alloy + WC. The customers can choose the laser pattern ofchina laser pointerthey like.
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.
5 kW CO2 lasers in the lining of the cast iron cylinder liners to deal with a width of 2 mm deep 0 to 5 mm spiral hardened zone. (6) Beijing Daheng automobile engine cylinder wall for laser hardening, laser power 900 W, scanning speed 40 mm / s, hardening bandwidth 5 mm deep 0 25 ~ 0 3 mm, the hardness of 63 HRC. The service life three times. Others, such as: precision shaped guide surface, spindle pole gear mold, cutting tools, reed, etc.. Combination; heat-affected zone of the substrate, the deformation is small; the extent of dilution of the substrate (typically 2% to 8%). Laser Surface Melting Treatment laser glazing, a high energy density laser beam on the metal surface, continuous scan, the formation of a thin layer of melted matrix endothermic effect of liquid metal in the molten bath to 106 ~ 108 K / s speed of cooling and solidification can refine casting, to reduce segregation. The light of china laser pointer should be carefully adjusted.
