摘要
Abstract
The laser cladding technology was used to clad stellite 6 and stellite 12 cobalt-based alloy coatings on the surfaces of 304 stainless steel and 2205 stainless steel substrates,respectively.The microhardness analysis,optical microscopy(OM),scanning electron microscopy(SEM),energy spectrometer(EDS)and simulated seawater potential corrosion test were used to investigate the microhardness,microstructural organization,phase,microtopography,molten pool morphology and corrosion performance of the two alloy cladding layers on different stainless steel substrates.Combined with the laser cladding process,the distributions of crystal phases and Co,Cr components in the bottom,middle and top layers of the cladding layer was analyzed.Through comparative analysis,it was found that the stellite 12 coating on the 2205 duplex stainless steel substrate had higher interfacial hardness of the cladding layer.The corrosion test showed that the stellite 12 coating had better corrosion resistance than the stellite 6 coating.关键词
