在我厂与日本合作生产的车床中,有三十多种齿轮、花键轴、尾座主轴的键槽和螺纹部位要求防渗处理。工艺流程要求机械加工→涂防渗涂料→渗碳淬火→机械加工(铣键槽和加工螺纹)。我厂先后采用日本和国产涂料,都未收到良好效果,严重影响生产。后我厂研制成功了82-1防渗碳涂料。经 In our factory and Japan co-production lathe, there are more than thirty kinds of gears, spline shaft, tailstock spindle keyway and threaded parts require anti-seepage treatment. Process requirements of machining → coating impermeable coating → carburizing and quenching → machining (milling keyway and processing thread). Our factory has adopted Japan and domestic coatings, have not received good results, seriously affecting the production. After my factory successfully developed 82-1 anti-carburizing coating. through
