【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）。更多还原

【Abstract】 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 adhesion(about 60%), and enhanced corrosion resistance(with a corrosion current density of 2.944 μA/cm~2 lower).更多还原
