现行机械零件的发黑工艺一般是用热处理方法进行的,即在140～150℃的工作温度下,在氧化溶液中经30～60min,在零件表面生成一层均匀的氧化膜,以达到防锈的目的。现介绍一种常温条件下发黑的新工艺。 常温发黑是用SRB-1发黑剂取代原热处理中的氧化溶液,在常温5～40℃,1～6min完成发黑工艺的过程,然后以DWO-1脱水防锈油取代原来热处理发黑后的皂化、水煮、干燥、上油的工艺。常温发黑工艺流程为:去 Current mechanical parts blackening process is generally carried out by heat treatment, that is, at the operating temperature of 140 ~ 150 ℃, the oxidation solution by 30 ~ 60min, the surface of the workpiece to generate a uniform oxide film to achieve anti-rust the goal of. Is introduced at room temperature under a new black technology. Blackening at room temperature is the use of SRB-1 blackening agent to replace the original heat treatment of the oxidation solution at room temperature 5 ~ 40 ℃, 1 ~ 6min to complete the blackening process, and then DWO-1 dehydration anti-rust oil instead of the original heat treatment of black After saponification, boiled, dry, oiled craft. Blackening process at room temperature to: go
