摘　　要：离子化气流辅助切削是将电离后的气流喷向切削区以起到润滑冷却作用的切削方式。分别在空气、空气流、离子化空气流、氮等离子体射流等气氛中进行304不锈钢的摩擦磨损和切削试验。结果显示,离子化空气流气氛具有良好的冷却润滑作用,摩擦因数相比干摩擦降低约46%,切向切削力和后刀面磨损相比干切削分别下降约24%和69%,并可显著减少黏着磨损和积屑瘤,大幅提高304不锈钢的摩擦磨损性能和切削加工效果。The ionized air assisted cutting is a cutting method, in which the ionized air is jetted to the cutting zone to achieve a lubricating and cooling effect. Friction and wear tests together with cutting tests of 304 stainless steel were conducted in the atmospheres of air, air jet, ionized air jet and nitrogen plasma jet, respectively. The results prove that the ionized air jet has a favorable cooling and lubricating performance. The friction coefficient decreases by about 46% compared with dry friction. The cutting force and the flank wear decrease by about 24% and 69%, respectively, compared with the dry cutting. The adhesive wear and the build up edge also decrease significantly, and the friction and wear performance and the machinability of 304 stainless steel are remarkably raised.
