复合涂层的制备是一种创新的方法，以改善机械和摩擦学性能方面的零部件表面的高速氧燃料（HVOF）和物理气相沉积（PVD）技术相结合。研究了HVOF Cr 3C 2-NiCr厚中间层和PVD TiN薄顶层复合涂层的结构、力学性能和高温摩擦学性能，并与Cr 3C 2-NiCr涂层和TiN单层涂层进行了比较。结果表明，Cr 3C 2-NiCr/TiN复合涂层具有较高的硬度、弹性模量、H/E和H3/E2比，比单一TiN涂层具有更好的上级承载能力。Cr 3C 2-NiCr中间层的引入不影响TiN膜的微观结构，但显著提高了TiN膜与基体的结合强度，以及在不同温度下与WC球摩擦时的耐磨性。此外，通过研究高温摩擦条件下摩擦表面的形貌和结构变化，揭示了Cr 3C 2-NiCr涂层、TiN涂层和Cr 3C 2-NiCr/TiN复合涂层的摩擦磨损机理。
Preparation of duplex coating is an innovative way to improve components surface in terms of mechanical and tribological properties by the combination of high velocity oxy-fuel (HVOF) and physical vapor deposition (PVD) technologies. The present work focused on the construction, mechanical properties and high temperature tribological behaviors of the duplex coating consisting of a thick HVOF Cr3C2-NiCr interlayer and a thin PVD TiN top layer, as well as compared it with the Cr3C2-NiCr coating and the single TiN film. The results showed that the Cr3C2-NiCr/TiN duplex coating exhibited higher hardness, elastic modulus,H/EandH3/E2ratios and superior load-bearing capacity than the single TiN film. The introduction of Cr3C2-NiCr intermediate layer did not affect the microstructure of TiN film but significantly improved the adhesion strength between TiN film and substrate, as well as the wear resistance sliding against WC ball at different temperatures. In addition, the friction and wear mechanism of the Cr3C2-NiCr coating, TiN film and Cr3C2-NiCr/TiN duplex coating was revealed by investigating the friction-induced morphological and structural evolutions of the sliding surface at elevated temperature.
