Abstract

The WO₃/TiO₂ composite coatings with varying amorphous content were fabricated in electrolytes with varying addition of tungsten source, and their tribological properties were tested from 25 ℃ to 600 ℃. The results indicated the composite coatings showed better mechanical and tribological properties at room temperature and exhibited superior wear resistance at high temperatures especially for 400 ℃. The enhanced high-temperature wear resistance was attributed to the formation of nanocrystals and the establishment of amorphous-crystal heterointerface, which effectively impedes dislocation movement and makes them accumulate dispersed along the interface because of the small size of nanocrystals. This work offers a theoretical foundation for enhancing the wear properties of the coatings under high-temperature conditions through the construction of an amorphous-crystal structure.

通过在 WO3/TiO2 复合涂层中构建非晶-晶体异质面结构增强高温耐磨性

在不同钨源添加量的电解液中制备了不同非晶含量的 WO3/TiO2 复合涂层，并测试了其在 25 ℃ 至 600 ℃ 的摩擦学性能。结果表明，复合涂层在室温下具有更好的机械性能和摩擦学性能，在高温下尤其是 400 ℃ 时表现出优异的耐磨性。高温耐磨性的增强归因于纳米晶体的形成和非晶-晶体异质界面的建立，由于纳米晶体尺寸小，能有效阻碍位错运动并使其沿界面分散聚集。这项研究为通过构建非晶结构提高涂层在高温条件下的磨损性能提供了理论基础。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
