| 摘 要： | 采用真空钎焊技术，将ＷＣ－Ｃｏ硬质合金粉和ｉＣｒＢＳｉ（ＡＷＳ ＢＮｉ－２）合金粉钎焊到４５＃钢表面，得到（ＷＣ－Ｃｏ／ｎｉＣｒＢＳｉ）复合钎焊涂层。在不同钎焊工艺下，涂层自身 和层／基体间的拉伸结合强度分别达（１００－１４０）ＭＰａ和（３００－３６０）ＭＰａ。研究了Ｃｏ含量对（ＷＣ－Ｃｏ／ＮｉＣｒＢＳｉ）复合涂层磨损性能的影响。实验结果表明（ＷＣ－Ｃｏ／ＮｉＣｒＢＳｉ）复合涂层磨损性能高于同配比

| Abstract: | A composite WC-Co/ NiCrBSi brazing coating on 1045 steel surface was obtained by the vacuum brazing technique, using the WC-Co cemented carbide and NiCrBSi (AWS Ni-2) alloy powders. The tensile strength of coating and bonding strength between coating and substrate reached 100-140Mpa and 300-360Mpa, respectively, at different brazing conditions. The effect of Co concentration on wear-resistance of composite coating was investigated. The experiment results showed that the wear-resistance of (WC-Co/NiCrBSi) composite coating was higher than that of flame welding overlay with the same composition and CoCrW (stellite 6B) overlay. |
