Abstract

Al_xCr_1 – xN coatings of 2–4 μm thickness obtained via cathodic arc evaporation using Al_xCr_1 – x cathodes with x = 0, 0.5, 0.7, and 0.8 were studied. The influence of the chemical composition of coatings on topographical, mechanical, tribological, and corrosion properties was studied. It was found that the addition of aluminum to CrN coatings reduces the lattice parameter and crystallite size, increases the roughness, and improves corrosion properties. It was established that all coatings are wear-resistant, the lowest specific volumetric wear was 2.1 × 10^–17 m³/(N m) in macro tests and 2.6 × 10^–14 m³/(N m) in microcontact conditions for Al_0.70Cr_0.30N, coatings showed high values of adhesion strength.

AlCrN涂层的化学成分对其机械，摩擦学和腐蚀特性的影响

摘要

研究了使用x = 0、0.5、0.7和0.8的Al _x Cr _{1-  x}阴极通过阴极电弧蒸发获得的厚度为2-4μm的Al _x Cr _{1-  x} N涂层。研究了涂层化学成分对形貌，机械，摩擦学和腐蚀性能的影响。已经发现，在CrN涂层中添加铝会降低晶格参数和微晶尺寸，增加粗糙度，并改善腐蚀性能。已经确定所有涂层都是耐磨的，在宏观测试中最低的单位体积磨损为2.1×10 ^–17 m ³ /（N m）和2.6×10 ^–14 m对于Al _0.70 Cr _0.30 N，在微接触条件下为³ /（N m），涂层显示出高的粘合强度值。
