摘要
利用低压等离子体弧源离子渗氮技术在低压（４×１０^(－１)Ｐａ）、低温 （３５０～４００℃）条件下进行奥氏体不锈钢表面渗氮处理，可在奥氏体不锈钢表面形成硬度高、耐蚀性好，厚度１０μｍ左右的氮在奥氏体中的过饱和固溶体氨化层，最高表面氮浓度达到４５％左右。
The austenitic stainless steel was nitridied by a low pressure plasma arc ion nitriding process at the condition of 4 ×10^-1Pa and 350℃ ~460℃. An oversaturated solid solution nitriding layer with high hardness, improved corrosion-resistance and thickness of about 10ｕm could be formed. The maximum concentration of nitrogen at surface could reach about 45%.
