摘要
研究了在碳钢表面光束堆焊生成陶瓷颗粒增强复合材料表层的可行性 ,考察了陶瓷颗粒物理性质及其加入量等对复合材料表层质量的影响规律。试验结果表明 :陶瓷颗粒的密度及其与基体NiCrBSi合金间的润湿性对复合材料表层的成形有重要影响 ,与普通TiC及WC相比 ,由于WC/Ni与NiCrBSi合金的润湿性好 ,因此更适合用作以镍基合金为基的复合材料表层的颗粒增强相。在复合材料表层成形良好的前提下 。
The feasibility of producing ceramic particle reinforced composites on carbon steel by light beam surfacing was investigated and the influence of the physical properties and the addition quantity of ceramic particle on the quality of composite layer was studied. The test results show that the density of ceramic particle and the wettablity between ceramic and NiCrBSi alloy have important effect on the formability of composite layer. Compared with common TiC and WC,WC with Ni coating (WC/Ni) is more suitably used as particle reinforced phase of Ni based alloy matrix composite because of its good wettablity with NiCrBSi alloy. On the premise of acquiring good formation of composite layer, increasing the addition of ceramic particle can be favorable to heighten macrohardness of composite layer.
