摘要
利用扫描电镜、X射线衍射仪、显微硬度计、划痕仪、磨损实验仪等,研究了不同铝含量的Ti1-xAlxN涂层性能。结果表明:当铝含量约为52%时,经涂层处理试样的显微硬度、摩擦磨损性能都得到了很大的提高,能达到使用钛铝合金靶离子镀Ti1-xAlxN涂层的相应性能,而从经济性来说,利用独立钛、铝靶比钛铝合金靶制备Ti1-xAlxN涂层的成本要低得多,从而具有降低生产成本,提高生产效益的优势。
Microstroctures, vickers hardness, bonding strength and wear resistance of the coatings wore charactcrizd by SEM, XRD, micro-indentation, scratch and pin-on-disc wear testers. The results show that the micro-hardness is largely increased but the friction coefficient is quietly decreased at the 52% of Al content in the coatings. No distinct differences in comparison with the Ti-Al alloy target deposition on the properties are detected .In the economical aspects, the cost of Ti1-xAlxN deposition with independent Ti and Al targets is much lower than it with Ti-Al alloy target. Therefore, the production cost is decreased.
