由郑州工学院热处理研究室研制,洛阳龙门热处理料材厂生产的粉末硼氮共渗剂,在1989年荣获了国家发明四等奖。在此基础上,研制成功了自保护硼氮共渗膏剂。用该膏剂进行硼氮共渗时,只需在工件表面涂上一层3mm左右的膏剂,在干燥后即可直接在空气介质炉中进行加热处理。渗层厚度可达100～150μm,表面硬度HV1800～1850,且渗层 Developed by the Zhengzhou Institute of Technology heat treatment laboratory, Luoyang Longmen heat treatment of material production of powder boron nitride infiltration agent, in 1989 won the fourth prize of national invention. On this basis, the successful development of self-protection boronniton co-paste. When using this paste for boronitriding, it is only necessary to apply a layer of about 3 mm paste on the surface of the workpiece, and then directly heat it in an air-medium furnace after drying. Layer thickness up to 100 ~ 150μm, surface hardness HV1800 ~ 1850, and the infiltration layer
