从体育器械用镁合金的激光表面改性角度出发

运用X射线衍射仪、光学显微镜、显微硬度仪、磨损试验机及电化学测量系统

研究了激光熔覆复合涂层对合金母材物相、显微组织、显微硬度、耐磨性和耐腐蚀性能的影响。结果表明

经过激光表面改性后的AZ31镁合金的表面硬度、耐磨性和耐腐蚀性能得到极大提高

且当Al-Si质量比为6∶1的Al2O3、TiO2时综合性能最好。

effects of laser cladding composite coating on the microstructure

microhardness

wear resistance and corrosion resistance of magnesium matrix were investigated.The results show that

after laser surface modification

the surface hardness

wear resistance and corrosion resistance of AZ31 magnesium alloy are greatly improved

and with the mass ratio of Al-Si+Al2O3、TiO2of 6∶1

the desirable comprehensive properties can be presented.
