采用50%Ni-50%Cr（wt.%）耐蚀合金对高温合金进行表面改性，涂层，通过高压冷喷涂方法沉积。本研究的目的是检查这种冷涂层形成方法作为高温侵蚀腐蚀条件下应用的高温合金上的Ni-Cr涂层的制造来源的适用性。改性的高温合金表面的特点是孔隙率分析，扫描电子显微镜，背散射电子图像，能量色散X射线光谱，元素X射线映射和维氏显微硬度测试技术。选择具有与Inconel-601合金（UNS no.N06601）类似的组成的基底高温合金，以在高温下的恶劣条件下为涂覆的部件提供强度。
A superalloy surface is modified with corrosion resistant 50%Ni–50%Cr (wt.%) coating, deposited by high pressure cold spray method. The goal of this study is to check the suitability of this cold method of coating formation as a manufacturing source for Ni–Cr coating on the superalloy for applications in high temperature erosive–corrosive conditions. The modified superalloy surface is characterised by porosity analysis, scanning electron microscopy, backscattered electron images, energy dispersive X-ray spectroscopy, elemental X-ray mapping and Vicker's microhardness testing techniques. The substrate superalloy with composition similar to Inconel-601 alloy (UNS no. N06601) is selected for the purpose of providing strength to the coated components in the severe conditions at elevated temperature.
