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（EnergyDispersive Spectrometer）觀察其表面組織合金成份及分散性。

In this paper, mixed micron powder of titanium carbide and stainless steel is used to clad on the low-carbon steel by GTAW (gas tungsten arc welding method) while Friction coefficient and wear test are applied on slide motion without lubricant. It is implemented in a pin-on-ring mode on a T-53 wear testing machine. This research studies wearing performance and hardness to the mixing ratio on the titanium carbide cladded layer compared with those of the commercial guide rail and the way to surpass it. In addition, the microstructure of titanium carbide cladded layer is examined by using SEM (Scanning Electron Microscopy) and EDS (Energy Dispersive Spectrometer) to the results showing that the distribution of the titanium carbide particles is even.
