钢铁表面无硒发黑工艺的可行性探讨

To Explore the Feasibility of Non-Selenium Surface Blackening Technology of Iron and Steel

针对现有常温发黑工艺中使用的亚硒酸或二氧化硒具有毒性大、价格高的缺点，提出了以硫代 替硒与铜离子反应作为主成膜物质确立的无硒常温发黑体系是解决问题的有效方式之一，并对

As selenious acid or selenium dioxide used in cold blackening technology at present has such disadvantages as high poison and high price, the authors present that non-selenium cold blackening system established by main film former material with a reaction of Cu^(2+) and sulfur insteat of Se is one of effective solutions to the problem and explore the feasibility of main film former and the choice of other additives of the blackening system.
