硼渗入钢件表面,形成由硼铁化合物组成的渗硼层,可以显著提高钢件表面的硬度(可达 HV1200～2000)、耐磨性和红硬性。因此渗硼处理可用于在磨损条件下工作的机器零件.工具、模具和要求高红硬性的压铸模具等。根据我们的实践证明,Cr12MoV 钢的螺母六角套模经渗硼处理后,使用寿命可提高3～4倍。一、盐浴渗硼设备与操作渗硼设备为30千瓦外热式盐浴炉,坩埚直径为300毫米,深度为600毫米,由12毫米厚的1Cr18Ni9Ti 不锈钢板卷制焊接而成。盐浴配方为(重量%):硼砂(Na_2B_4O_7·10H_2O)90%,SiC10%。硼砂为工业纯
Boron infiltrated into the surface of the steel to form a boronizing layer composed of boron-iron compounds can significantly improve the hardness of the steel surface (up to HV1200 ~ 2000), wear resistance and red hardness. Therefore boronizing treatment can be used in working conditions under wear and tear parts of the machine tools, molds and require high red hardness of die-casting molds. According to our practice, Cr12MoV steel nut hexagonal die set after boronizing treatment, the service life can be increased by 3 to 4 times. First, the salt bath infiltration equipment and operation Infiltration equipment is 30 kilowatts outside the thermal salt bath furnace, the crucible diameter of 300 mm, a depth of 600 mm, made of 12 mm thick 1Cr18Ni9Ti stainless steel roll welded together. Salt bath formula (weight%): borax (Na_2B_4O_7 · 10H_2O) 90%, SiC10%. Borax is industrial pure
