Abstract

In this paper, CrAlSiN coatings with different interlayer designs (without interlayer, Cr interlayer, CrN interlayer and Cr/CrN interlayer) were successfully obtained on 316L stainless steel and single crystal silicon by multi-arc ion plating technique. Coating microstructure, mechanical, anticorrosion and tribological behaviors in artificial seawater were systematically investigated by XRD, SEM, XPS, TEM, nanoindentation, electrochemical workstation and frictional tester system. Results showed that the CrAlSiN layer presented a typical nanocrystalline/amorphous structure, which consisted of CrN, AlN and SiN phases. The Cr/CrN interlayer could obviously improve the adhesion, hardness and toughness of CrAlSiN coating. Compared with single CrAlSiN coating, the corrosion current density of Cr/CrN/CrAlSiN coating system was improved by 2 orders of magnitude and its inhibition efficiency was up to 98.82%. Under high applied load (15 N) condition, the CrAlSiN coating with Cr/CrN interlayer revealed the lowest COF (0.107 ± 0.009) and wear rate (7.3 × 10 ± 8.4 × 10 mm N m) in seawater, which primarily attributed to the synergistic effect of ideal adhesion force, outstanding toughness and effectively barrier ability.

摘要

在本文中，采用多弧离子镀技术在316L不锈钢和单晶硅上成功制备了具有不同中间层设计（无中间层、Cr中间层、CrN中间层和Cr/CrN中间层）的CrAlSiN涂层。通过XRD、SEM、XPS、TEM、纳米压痕、电化学工作站和摩擦测试仪系统，系统研究了涂层在人工海水中的微观结构、力学性能、耐腐蚀性能和摩擦学行为。结果表明，CrAlSiN涂层呈现典型的纳米晶/非晶结构，由CrN、AlN和SiN相组成。Cr/CrN中间层可显著提高CrAlSiN涂层的附着力、硬度和韧性。与单一CrAlSiN涂层相比，Cr/CrN/CrAlSiN涂层体系的腐蚀电流密度提高了2个数量级，缓蚀效率高达98.82%。在高载荷（15 N）条件下，具有Cr/CrN中间层的CrAlSiN涂层在海水中的摩擦系数最低（0.107±0.009），磨损率最低（7.3×10±8.4×10 mm N m），这主要归因于理想附着力、优异韧性和有效阻挡能力的协同作用。
