动能喷涂是一种用于热反应材料应用的多功能新工艺。使用平均粒径为 23.3 μm 的商用 NiCr 原料，使用氮气在 AISI 304 不锈钢上形成单道喷涂珠。改变气体温度和压力。根据气体条件观察喷涂珠的微观结构和厚度变化，并在单道喷涂珠横截面内的不同位置测量显微硬度。气体温度对增稠速率的影响比气体压力更大。
Kinetic spraying is a versatile new process for application of thermally reactive materials. A commercial NiCr feedstock with a mean particle size of 23.3 μm was used for the formation of a single pass spraying bead on AISI 304 stainless steel using nitrogen gas. Gas temperature and pressure were changed. The microstructure and thickness variation across the spraying bead were observed according to the gas condition, and the microhardness was measured at a different position within a cross-section of a single pass spraying bead. Gas temperature was shown to have a higher influence on the thickening rate than gas pressure.
