摘要

本文將碳化鈦與不銹鋼兩種微米級粉末混合，利用氬銲披覆於低碳鋼表面，以改善低碳鋼表面的耐磨耗性能，使用磨耗試驗機以銷對環進行乾磨耗實驗及測量摩擦係數，探討披覆於低碳鋼表面的硬度與耐磨耗性能可以超越商用導軌的碳化鈦比例，並以金相、SEM(Scanning Electron Microscopy)及EDS(Energy Dispersive Spectrometer)觀察其表面組織合金成份及分散性。

This paper utilizes micron powder of titanium carbide and stainless steel to clad on the low-carbon steel by the GTAW(gas tungsten arc welding method). Friction coeifficient and wear tests applied sliding motion without lubricant were performed in a pin-on-ring mode on a T-53 wear testing machine. This research study the wear performance of the titanium carbide cladded layer compared with that of the commercial guide rail. In addition, the microstructure of titanium carbide cladded layer was examined by using SEM(Scanning Electron Microscopy) and EDS(Energy Dispersive Spectrometer). We found that the distribution of the titanium carbide particles is even.
