本研究采用化学气相沉积技术在AISI316 L不锈钢上沉积了TiN和TiAlN涂层。分别用能量色散X射线分析(EDX)和X射线衍射法(XRD)分析了沉积层的成分和晶体结构。采用电化学动电位极化法研究了TiN涂层和TiAlN涂层在0.9wt%NaC l和SBF溶液中的耐蚀性，并采用球盘磨损法在2.5N载荷下以0.3m/S的滑动速度评价了其在干介质中的磨损行为。结果表明，TiN和TiAlN涂层均具有较好的耐蚀性，但TiAlN涂层的耐蚀性优于TiN涂层。TiAlN涂层提高了AISI316 L不锈钢的表面硬度，降低了摩擦因数，对腐蚀和磨损行为有积极的作用。
In this study, TiN and TiAlN coatings were deposited on AISI 316 L stainless steel substrates by PVD techniques. The composition and crystalline structure of the as-deposited coatings were analyzed by energy dispersive X-ray analysis (EDX) and X-ray diffraction (XRD) methods, respectively. The corrosion resistance studies of TiN-coated and TiAlN-coated samples were carried out in 0.9 wt % NaCl and SBF solutions using the electrochemical potentiodynamic polarization method and the wear behavior was evaluated with the ball-on-disk wear method at a sliding speed rate of 0.3 m/s under 2.5 N load in a dry medium. It was found that both TiN and TiAlN coatings exhibited relatively good corrosion resistance, however, TiAlN coatings showed a better corrosion resistance than TiN coatings. The TiAlN coating contributes positively against corrosion and wear behavior by increasing the surface hardness and by decreasing the friction coefficient of AISI 316 L stainless steel, respectively.
