摘要
以Mo粉、FeB合金粉和Fe粉为基本原料,分别加入Cr、Ni、C或同时加入Cr、Ni、C合金元素成分,采用原位反应真空液相烧结工艺,在Q235钢基体上制备三元硼化物金属陶瓷覆层材料。研究了合金组分对覆层材料耐腐蚀性的影响。结果表明,三元硼化物金属陶瓷覆层材料的覆层具有远比钢基体优越的耐蚀性,C组分的单独加入降低了覆层的耐蚀性,Cr、Ni组分的加入显著提高了覆层的耐蚀性,同时加入Cr、Ni、C作为合金组分使覆层具有最佳的耐蚀性。
Using Mo powder, B-Fe alloy powder and Fe powder as raw materials, joined with Cr, Ni, C ingredient respectively, or joined with Cr, Ni, C ingredient synchronously, ternary boride cermet clad materials were prepared on Q235 steel substrate by in situ reaction and vacuum liquid phase sintering technology. The influence of alloy ingredient on corrosion resistance of ternary boride cermet clad materials was studied. The experimental results indicated that cladding has better corrosion resistance than steel substrate, the corrosion resistance of cladding was deteriorated when C ingredient joined into cladding, however improved greatly when Cr or Ni ingredient joined. The optimal corrosion resistance of cladding was obtained when Cr, Ni, C ingredients joined into cladding synchronously.
