摘要
在混有固定比例焊剂431、硼酐和冰晶石的Fe55合金粉末中添加Mn、B4C和SiC,采用中频熔敷技术在42CrMo钢基体上制备Fe基合金熔敷层。通过硬度正交试验,确定最优的Mn、B4C和SiC添加比例,并分析Mn、B4C和SiC对熔敷层性能的影响。结果表明,添加Mn、B4C、SiC的Fe基合金熔敷层,其硬度可达62.6 HRC;当Mn、B4C、SiC的添加量分别为8.0%、2.5%和5.5%时,熔敷层的硬度和耐磨性最好。
Adding Mn, B4C and SiC to the Fe55 alloy powder which containing fixed rate HJ431, boron oxide and cryolite. Cladding coating of ferroaUoy was prepared by medium frequency deposition technology on 42CrMo steel substrate. The optimal added proportion ofMn, B4C and SiC was determined through the orthogonal test of hardness. And the influences ofMn, B4C and SiC on the performance of cladding coating were analyzed. The results indicate that the hardness of ferroalloy cladding coating can reach to 62.6 HRC through adding Mn, B4C and SiC. When the amount of Mn, B4C and SiC is 8.0%, 2.5% and 5.5% respectively, the hardness and wear resistance of cladding coating are the best.
