采用化学气相扩渗法研究了稀土对20钢、45钢表面进行多组分共渗的耐腐蚀性能。实验结果表明:经稀土扩渗处理后的钢表面用动电位扫描、中性盐雾法、失重法以及电化学嗓声法对孔蚀测定,证实20钢、45钢耐蚀性能均有显著提高。
The chemical vapor deposition method was used to study the corrosion resistance of rare earths on multi-component co-infiltration of 20 steel and 45 steel. The experimental results show that corrosion resistance of 20 steel and 45 steel is significantly enhanced by potentiodynamic scanning, neutral salt spray, weight loss method and electrochemical acoustic method. .
