The blackening process is meanly used on stainless steel treatment. The black oxide film is generated on stainless steel surface by soaking workpieces in boiling plating liquid. It prevents the workpiece from deformation, does not affect conductivity, decreases light reflection, raises corrosion resistance, does not cause hydrogen embrittlement, and also has decorative fuction with black exterior. This material can be applied to optical industry, mechanism parts, aerospace industry, bicycle industry, automobile industry, etc. The sewage generated by the process can be proper treated in circulating water system to prevent from pollution.more
