中文摘要 | 本文主要是研究鎳基合金硬面銲補層在添加不同合金元素後,在磨料磨耗下, 其顯微組織及硬度對耐磨耗性的影響。結果顯示,在石英砂的磨耗下,提高銲補層的硬度可 以明顯改善其磨料磨耗阻抗。在碳化矽的磨耗下,並無法直接由銲補層的硬度值判斷其耐磨 耗性,而必須同時考慮銲補層的加工硬化性能及碳化物形態,但是,同時添加碳及鉻元素則 可以明顯地改善此鎳基硬面銲補的磨料磨耗阻抗。 |
英文摘要 | In this work, we examine the microstructure and the hardness of the nickel-base hardfacing alloy and their influence on the abrasive wear resistance of a deposited layer when different alloy elements were added. Our results indicate that 1) Under the wear test using quartz, the abrasive wear resistance of the layer can be improved visibly by increasing the hardness of the deposited layer. 2) Under the wear test using silicon carbide. the same effect on the abrasive wear resistance is indistinct. T e effect of the work hardening ability and the carbide structure of the deposited layer must be considered simultaneously. If carbon and chromium were added into the nickel-base hardfacing alloy, the abrasive wear resistance of the material is improved. |
