今年四月二十二日,省科委在我校主持并通过了机械二系热处理教研室孙轩华等老师研究的“盐浴法稀土——硼多元共渗”科研成果技术鉴定。 此项新技术经沈阳纺织机械厂在并条机喇叭口和沈阳手表厂的冷冲模具的现场考核,证明:分别提高使用寿命15倍以上和30倍。并且具有共渗温度低、渗层厚、性能优越、寿命 April 22 this year, the Provincial Science and Technology Commission in our school presided over and adopted the mechanical heat treatment department Sunxuan Hua and other teachers, “Salt Bath Rare Earth - boron multiple infiltration” scientific research and technical appraisal. The new technology by the Shenyang Textile Machinery Factory in the drawframe and Shenyang Watch Factory punch die site assessment to prove: respectively, to improve life expectancy of more than 15 times and 30 times. And has a low infiltration temperature, infiltration layer thickness, superior performance, life expectancy
