本文探討添加不同比例稀土元素(氧化鑭),對於SKD61模具鋼表面氬銲被覆硼化鎢(WB)陶瓷被覆層之顯微結構與磨耗行為的影響。並找出影響耐磨耗能力之主要關鍵,以做為SKD61模具鋼表面耐磨耗改質的依據。
研究結果顯示,WB系列之被覆層則屬於析出強化型機構。在WB被覆層中添加適量之氧化鑭(La2O3)可以使基地的顯微組織微細化,並促進析出物之成長。添加氧化鑭(La2O3)的WB被覆層內的析出相較厚實,具較佳之機械互鎖效應,其中以添加3.0%氧化鑭之WB被覆層效果最佳,使其被覆層之耐磨耗能力有效地提升。然而,值得注意的是必須添加適量的氧化鑭(La2O3),過量的氧化鑭(La2O3)反而無益於微結構改善與耐磨耗能力。
This thesis studies the effect of rare earth (La2O3) on microstructure morphology and wear resistance of clad layer for SKD61 tool steel cladded with WB powder. In addition, the major factors that influence wear performance of clad layer were found out in this study.
According to the results of this study, WB clad layers were strengthened by the precipitation of reinforcing phases. The results show that adding suitable amount of La2O3 can promote microstructure refining and precipitates growing in WB clad layer. Thicker precipitates possess better mechanical interlocking effect and can increase significantly the wear-resistance ability in WB cladding specimens. The wear performance of WB-3.0% La2O3 clad layer was improved obviously. Nevertheless, it should be emphasized that it is suitable to add certain amount of La2O3. And too much La2O3 would not be beneficial to improve the microstructure and wear performance.
