摘要
研究开发了一种用微量添加剂取代铬酐的新型电解抛光工艺 ,适用于Cr13型马氏体不锈钢工件在真空热处理后的直接电化学光亮处理。通过加入增稠剂和缓蚀剂 ,降低了电解液的酸含量 ,抑制了工件表面的局部腐蚀 ,可得到光亮平整的表面 ,抛光液寿命长。
A new electropolishing technique with substitution of micro additive for CrO 3 was developed.The process could be applicable to bright treatment for the Cr13 martensite stainless steel parts after vaccum thermo treating.The total amount of acids in the bath could be reduced,thus the local corrosion being inhibited.The CrO 3 free solution also could have the advantage of enviromental protection.
