摘要/Abstract

摘要： 叙述了不锈钢表面纳米化技术-表面机械研磨处理，喷丸法，异步轧制法和激光表面融熔法和不锈钢块体纳米化技术-机械合金法，惰性气体凝聚原位加压法，电化学沉积法，非晶晶化法和大塑性变形法。纳米化不锈钢的耐蚀性能直接受到纳米晶结构的影响，结构均匀，无位错，无应力是获得优异耐蚀性的前提。

关键词: 不锈钢纳米化工艺耐蚀性

Abstract: The surface nanocrystallization technology of stainless steel such as surface mechanical attrition treatment, shot peering,cross shear rolling and laser surface melting and the bulk nanostructured technology such as mechanical alloy method,inert gas condensation in-situ compression,electrochemical deposition,crystallized from amorphous solid and se- vere plastic deformation method is presented. The corrosion resistance of nanocrystallined stainless steel is affected directly by nanocrystalline structure and the features including uniform structure,free-dislocation and intemal stress are precondi- tions to get excellent corrosion resistance.

Key words: Stainless Steel,Nanocrystallization Technology,Corrosion resistance
