一、前言不锈钢是制造仪表和机构元件的重要材料,其主要性质之一是在特定的腐蚀介质中具有高度的化学稳定性。不锈钢的这一优点,在材料应用中是人们极其需要的,遗憾的是也给生产过程带来不利影响,例如同其他金属材料相比,不锈钢的表面处理技术就比较复杂,因工艺方法选择不当,在生产过程中经常导致材料报废或材料性能的剧烈降低;由于缺乏有效的 I. INTRODUCTION Stainless steel is an important material for the manufacture of instrumentation and mechanical components. One of its main properties is its high chemical stability in specific corrosive media. This advantage of stainless steel, which is extremely needed in material applications, unfortunately also has an adverse effect on the production process. For example, compared with other metal materials, stainless steel surface treatment technology is more complex, due to improper selection of process methods , Often leads to material scrap or drastic reduction of material properties in the production process; due to the lack of effective
