在N2/Ar混合气体中，采用电弧离子镀Ti和直流磁控溅射Si相结合的复合镀膜技术，在不锈钢基体上制备了Ti-Si-N涂层。随着Ti-Si-N涂层中Si含量的增加，涂层的显微组织由柱状晶向纳米复合晶转变。室温下在3wt%NaCl溶液中进行的阳极极化测量表明，具有较高的Si含量的Ti-Si-N涂层具有更好的耐腐蚀性，由于形成了独特的纳米复合微结构，其中高耐腐蚀性的非晶SiNx相包围TiN微晶。
Ti-Si-N coatings were deposited on stainless steel substrates using a hybrid coating system consisting of arc ion plating for Ti and a dc magnetron sputtering technique for Si in a gaseous N 2 /Ar mixture. On increasing the Si content in the Ti-Si-N coating, the microstructure changed from columnar to a nanocomposite. The anodic polarization measurement performed in 3 wt % NaCl solutions at room temperature revealed that Ti-Si-N coatings with higher Si contents had better corrosion resistance due to the formation of a unique nanocomposite microstructure where the highly corrosion-resistive amorphous SiN x phases surrounded the TiN crystallites.
