摘　　要：采用磁控溅射技术在ZK60镁合金表面制备了M-TaC多层涂层,并以TaC单层涂层作为对照,研究了涂层的微观结构、结合性能和耐腐蚀性能。结果表明,涂层呈多孔柱状结构和亲水性,能显著提高ZK60镁合金的耐腐蚀性能。相比于TaC单层涂层,M-TaC多层涂层的表面粗糙度增大,亲水性减弱,结合力提高(约60%),耐腐蚀性能增强(腐蚀电流密度减小2.382μA/cm^(2))。M-TaC multilayer coatings were prepared on the surface of ZK60 magnesium alloy with magnetron sputtering technology.The layer’s microstructure,adhesion performance,and corrosion resistance were investigated with TaC single-layer coating as the control.The results indicated the coatings exhibiting a porous columnar structure and hydrophilicity,which could significantly improve the corrosion resistance of ZK60 magnesium alloy.Compared to TaC single-layer coatings,M-TaC multilayer coatings showed increased surface roughness,decreased hydrophilicity,improved 2 adhesion(about 60%),and enhanced corrosion resistance(with a corrosion current density of 2.944μA/cm^(2) lower).
