Abstract

Plasma immersion ion implantation (PIII) of nitrogen is low-temperature surface technology which enables the improvement of tribological properties without a deterioration of the corrosion behavior of austenitic stainless steels. In this paper the corrosion properties of PIII-treated AISI 316L stainless steel surfaces are evaluated by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PP) and exposure immersion tests (all carried out in the 0.9 wt. % NaCl solution at 37 ± 0.5 °C) and compared with a non-treated surface. Results of the three performed independent corrosion tests consistently confirmed a significant increase in the corrosion resistance after two doses of PIII nitriding.

摘要

等离子体浸没离子注入氮是一种低温表面技术，它能够在不降低奥氏体不锈钢腐蚀性能的情况下改善其摩擦学性能。本文通过电化学阻抗谱（EIS）、动电位极化（PP）和浸泡试验（均在37±0.5℃的0.9 wt.% NaCl溶液中进行）对经等离子体浸没离子注入处理的AISI 316L不锈钢表面的腐蚀性能进行了评估，并与未处理的表面进行了比较。三项独立腐蚀试验的结果一致证实，经过两次剂量的等离子体浸没离子注入渗氮后，耐腐蚀性显著提高。
