| 摘 要： | 以WC，NiAl，NiB和Ni粉末等混合球磨、烧结制备复合材料焊条，在球磨过程中，WC颗粒被破碎，NiAl，NiB和Ni反应生成金属间化合物Ni3A1。用氩弧焊将这种复合材料焊条堆焊在1Cr25Ni20Si2不锈钢的表面，形成5mm厚的金属间化合物耐磨复合材料。堆焊过程中，部分WC溶解，析出新碳化物W2C，Ni3Al转变成新金属间化合物Ni3(A1Ti)C。这种复合材料的耐磨性可达45钢的3倍以上。

| Abstract: | Composite welding rods were fabricated by milling and sintering mixtures of WC,NiAl,NiB and Ni powders.In milling,WC particles were broken,and NiAl,NiB and Ni powders reacted to form intermetallic compounds.WC/intermeatllic composite wear resistant coatings (5mm in thickness) were made using this kind of welding rods on the surfaces of 1Cr25Ni20Si2 steel.Partial WC particles dissolved to precipitate new carbide W 2C,and the matrix Ni 3Al transformed one new intermetallic compound Ni 3(AlTi)C.The wear resistance of this composites was 3 times that of 45 steel. |
