Abstract

TiN coatings have been deposited using cathodic arc deposition at various nitrogen pressures and deposition temperatures. The structure and elemental coating composition are analyzed using a scanning electron microscope and an energy dispersive spectrometer. The mechanical properties and adhesion strength of the coating are measured using nanoindentation and scratch testing. The degree of wear is investigated with a tribometer using the ball-on-disk test method. The analysis of the results is carried out by the methods of two-factor orthogonal experiment planning with optimization elements. The results show that the coating structure has a columnar (fibrous) morphology, the composition is close to stoichiometric. The moment of coating destruction, when determining the adhesive strength, occurs at a load of about 600 mN. On the basis of the obtained regression equations for the optimized values of hardness, plasticity index and wear degree, the values of the process parameters of deposition should be in intervals T = 350–430°С and P = 0.065–0.075 Pa.

获得 TiN 真空离子等离子涂层的基本加工因素对其机械和摩擦学特性的影响

摘要在不同的氮气压力和沉积温度下，采用阴极电弧沉积法沉积了氮化钛涂层。使用扫描电子显微镜和能量色散光谱仪分析了涂层的结构和元素组成。利用纳米压痕和划痕测试测量了涂层的机械性能和附着强度。使用摩擦磨损测试仪，采用球盘测试法对磨损程度进行了研究。结果分析采用了带有优化元素的双因素正交实验规划方法。结果表明，涂层结构具有柱状（纤维状）形态，成分接近于化学计量。在确定粘合强度时，涂层破坏的时刻发生在大约 600 mN 的载荷下。根据所得到的硬度、塑性指数和磨损程度优化值的回归方程，沉积工艺参数值的区间应为 T = 350-430°С 和 P = 0.065-0.075 Pa。
