摘　　要：以数控机床床身用钢为研究对象,采用正交实验法对机床用钢的喷射沉积工艺进行了设计与研究,分析了变形温度、变形速度、变形量和升温速度对致密化效果的影响,并优化了喷射沉积工艺。结果表明,适宜的喷射沉积致密化工艺为变形温度840℃、变形速度0.1 mm/s、变形量60%、升温速度10℃/s。Taking the steel used for CNC machine as research object, the spray deposition process of machine tool steel was designed and researched by the method of orthogonal experiment, the effect of deformation temperature, deformation rate, deformation amount and heating rate on the compact property were studied, and the spray deposition process was optimized. The results show that the suitable spray deposition densification process is the deformation temperature of 840 ℃,the deformation rate of 0.1 mm/s, the deformation amount of 60% and the heating rate of 10 ℃/s.
