Stainless Steel Sheet Metal Processing Should Pay Attention To What Matters
- Dec 27, 2017 -

Ni based self melting alloy plays a role of bonding phase in the composite coating, so that the coating has high hardness and toughness at the same time, which is also beneficial to the improvement of the wear resistance of the clad coating. The hardness and wear resistance of laser clad metal ceramic composite coatings in Suzhou precision sheet metal processing are closely related to the technological parameters of laser cladding besides the type, size and distribution of ceramic phases. Study on the surface of A3 steel by laser cladding Fe+WC ceramic metal composite coating microhardness show that due to the dissolution of WC. The content of W was significantly increased in the bonding metal, is beneficial to improving the hardness of the metal bond; at the same time, the scanning speed is slower, the dilution rate of cladding coating is also higher, and the dilution rate increased the microhardness of bonding metal reduction.  Therefore, the best scanning speed is present to make the coating with the highest hardness. (1) the wear resistance of laser cladding coating wear resistance corrosion resistance mainly (2) WangA H by YAG laser on SiC (Mg-6%Zn-0.5%Zr) reinforced ZK60 magnesium matrix composite cladding Al-Si alloy, the polarization curves of composite materials appear obvious passivation, corrosion potential is greatly improved, the corrosion current density decreased significantly. Hu Qianwu of the Mg-SiC composite coating of copper alloy, and then use the 2 kW- Nd: Suzhou laser cutting processing YAG laser for laser cladding, the cladding layer of Cu60Zn40 alloy and Mg-SiC matrix after good fusion, the corrosion potential of Ecorr laser cladding specimens is 3.7 times higher than the untreated, the corrosion current density of Jcorr decreased by about 22 times. 2.
