Abstract
Cu-based coatings are ideal for protecting aerospace and industrial components from wear and failure. Traditionally applied using high-temperature methods like Atmospheric Plasma Spraying (APS) and High-Velocity Oxy-Fuel (HVOF), these techniques often increase oxygen content in coatings. Low-temperature processes, such as High-Velocity Air-Fuel (HVAF), reduce oxygen content, costs, and energy use while maintaining performance. This study investigates CuNiIn coatings deposited via Internal Diameter High-Velocity Air-Fuel (ID-HVAF) and HVOF. Both processes produced dense coatings with minimal oxidation. Friction increased from ∼0.49 at 25°C to ∼0.7 at 450°C, with minimal wear at 25°C and significant wear at 450°C. Ex-situ analysis revealed copper oxides glaze at 25°C reduced friction, while abrasive grooves dominated wear at 450°C.
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.
