摘要

本文探討使用噴覆技術將不同抗磨材料噴覆於碳鋼表面，其對於噴覆層的結合力、表面硬度、材料磨耗及主軸表面磨潤特性之影響。
　　實驗採用噴覆設備將抗磨材料噴覆於低碳鋼及軸承鋼表面，再研磨使試片噴覆層至相同厚度，最後利用磨耗試驗機測試其噴覆層與油封材料間之摩擦特性。
　　實驗結果顯示在相同硬度下，其表面粗糙度越低磨潤特性越好。噴覆Ni-Cr-B-Si合金粉末與 陶瓷於低碳鋼試片能致使基材表面硬度(HRC)提升約10倍，合金粉末須加以融潤，噴覆層與基材有良好的結合效果及磨料顆粒均勻分佈；若使用AISI5210軸承鋼試片噴覆Ni-Cr-B-Si合金或 陶瓷於表面，因噴覆表面結構緻密，降低表面摩擦係數和粗糙度，進而提高噴覆層的耐磨性。

In this paper, studying the coating adhesion, binding force, hardness of surface, wear and friction performance of journal surface, machine journal is covered with different wear-resistant material with flame spraying technology.
　　To start with spraying wear-resistant material on the surface of low carbon steel and bearing steel. Obviously, milling sprayed coatings to the same thickness. Finally, we measure the friction characteristics between seal and sprayed coatings by abrasion testing machine.
　　This study show low surface roughness can obtain better friction performance of journal surface. Melting Ni-Cr-B-Si powder on low carbon steel, it causes sprayed coatings has great binding force and distribution of particles with substrate, which improves hardness of surface 10 times. If we use AISI5210 steel, covering Ni-Cr-B-Si alloy or ceramics on surface. Because close texture, it’s also reduce the friction coefficient, roughness and improve wearing resistance in the same time.
