    摘要:

    離子化氣流輔助切削是將電離后的氣流噴向切削區(qū)以起到潤滑冷卻作用的切削方式,。分別在空氣,、空氣流,、離子化空氣流,、氮等離子體射流等氣氛中進行304不銹鋼的摩擦磨損和切削試驗,。結(jié)果顯示,，離子化空氣流氣氛具有良好的冷卻潤滑作用,，摩擦因數(shù)相比干摩擦降低約46%,，切向切削力和后刀面磨損相比干切削分別下降約24%和69%，并可顯著減少黏著磨損和積屑瘤,，大幅提高304不銹鋼的摩擦磨損性能和切削加工效果,。

    Abstract:

    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.
