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。
Under low pressure (4 × 10 -1 Pa) and low temperature (350 ~ 400 ℃), nitriding treatment of austenitic stainless steel is carried out by low pressure plasma arc ion nitriding, which can be applied to the surface of austenitic stainless steel Formation of high hardness, corrosion resistance, thickness of about 10μm of nitrogen in austenite supersaturated solid solution ammoniated layer, the highest surface nitrogen concentration of about 45%.
