本研究为了采用冷喷涂技术制备高碳钢涂层，对载气温度、压力等喷涂条件进行了研究。同时，为了提高冷喷涂高碳钢的沉积效率和控制涂层硬度，开发并优化了高碳和低碳钢混合粉末及其机械研磨粉末。通过使用冷喷涂技术，成功地实现了高碳钢的颗粒沉积。此外，通过应用混合和机械研磨粉末，孔隙率降低，沉积效率提高。此外，使用这些粉末，可以控制硬度值。特别是，当使用机械研磨粉末时，很难识别涂层和基材之间的界面。因此认为涂层和基材之间的结合是极好的。
In this study, in order to make high carbon steel coating by cold spray technique, spray conditions such as carrier gas temperature and pressure etc. were investigated. And also, in order to improve deposition efficiency and control coating hardness of cold-sprayed high carbon steel, high carbon and mild steel mixed powder and its mechanical milled powder were developed and were optimized. By using the cold-spray technique, particle deposition of a high carbon steel was successful. Moreover, by applying mixed and mechanical milled powders, the porosity ratio was decreased and deposition efficiency was improved. Furthermore, using these powders, it is possible to control the hardness value. Especially, when using mechanical milled powder, it is very difficult to identify the interface between the coating and the substrate. The bonding between the coating and the substrate is thus considered to be excellent.
