Abstract

This study aims to evaluate the tribological performance of copper coatings developed by high-velocity air fuel (HVAF) and cold spray (CS) which are two important low-temperature solid-state deposition processes among spraying techniques. Reciprocating sliding wear tests against alumina balls were conducted at room (25 °C) and high (300 °C) temperatures. HVAF and CS coatings showed similar friction coefficients, both with a greater friction at high temperature. However, they exhibited different wear behaviors, where HVAF coating showed increased wear depth with temperature raise, while wear depth of CS coatings remained similar. Ex situ characterizations performed from the top and cross section of the worn surfaces by SEM, EDX, and Raman spectroscopy indicated profound oxidation occurred inside the wear tracks and higher wear of HVAF coating at high temperature was mainly due to greater oxidation and more cracks inside the tribolayer.

HVAF和冷喷涂沉积铜涂层摩擦学性能的比较研究

本文研究了低温固相喷涂技术中两种重要的低温固相喷涂技术——高速空气燃料（HVAF）和冷喷涂（CS）制备的铜涂层的摩擦学性能。在室温（25°C）和高温（300°C）下对氧化铝球进行往复滑动磨损试验。HVAF涂层与CS涂层具有相似的摩擦系数，在高温下均具有较大的摩擦系数。然而，它们表现出不同的磨损行为，HVAF涂层的磨损深度随着温度的升高而增加，而CS涂层的磨损深度保持不变。利用SEM、EDX和拉曼光谱对磨损表面的顶部和横截面进行了非原位表征，结果表明磨损轨迹内部发生了严重的氧化，高温下HVAF涂层的高磨损主要是由于摩擦层内部氧化加剧和裂纹增多。
