TiSiN 和 TiSiN/Ag 涂层通过多离子弧电镀制备，并在 650 °C 下退火 5 小时。结果发现，退火涂层比沉积涂层具有更好的腐蚀和摩擦腐蚀性能。由于孔隙率的降低，退火后的 TiSiN 涂层在电化学阻抗谱测试中表现出较慢的失效过程。此外，退火过程可以降低涂层中的残余应力，从而导致摩擦腐蚀测试期间的摩擦系数较低。此外，Ag在TiSiN/Ag多层涂层的摩擦腐蚀实验中发挥了重要作用。总的来说，热处理可以改善涂层的腐蚀和摩擦腐蚀性能，退火后的TiSiN/Ag涂层表现出最好的摩擦腐蚀性能。
TiSiN and TiSiN/Ag coatings were prepared by multi ion arc plating and annealed at 650 °C for 5 h. It was found that the annealed coatings had the better corrosion and tribocorrosion properties than as-deposited coatings. The annealed TiSiN coatings exhibited a slower failure process in electrochemical impedance spectroscopy in test due to the reduction of porosities. Moreover, the annealing process can decrease the residual stresses in the coating which can lead to the low coefficient of friction during tribocorrosion tests. What's more, Ag played an important role in tribocorrosion experiment in TiSiN/Ag multilayer coatings. In general, the thermal treatment can improve the corrosion and tribocorrosion properties of the coatings and annealed TiSiN/Ag coatings exhibited the best tribocorrosion performance.
