本文利用噴覆技術對於不同抗磨材料噴覆在碳鋼表面，探討其噴覆層的表面硬度、材料結合力、材料磨耗及主軸表面磨潤性質之影響。實驗採用火焰噴覆設備將抗磨材料噴覆於低碳鋼及軸承鋼表面，經研磨使試片噴覆層至相同厚度，然後利用磨耗試驗機測試噴覆面層與油封材料之間的摩擦性質。實驗結果表示在相同的硬度條件下，當表面粗糙度愈低，理論的磨潤性質愈好。噴覆Ni-Cr-B-Si合金粉末與陶瓷粉末於低碳鋼試片，合金粉末須加以融潤，使噴覆材與基材有良好的結合效果以及磨料上的顆粒分佈均勻，使材料表面上的硬度(HRC)提升約10倍；若基材使用AISI5210軸承鋼，其噴覆層結構緻密，降低表面的摩擦係數和粗糙度，提高噴覆層的耐磨性質。

In this paper, spray coating technology is used to spray different wear resistance materials on the surface of carbon steel. The effects of the surface hardness, material binding force, material wear, and spindle surface tribological properties of the spray coating were investigated. We are spraying the wear resistance material on the surface of the low carbon steel and the bearing steel by the flame spray technology and grinding them to the same thickness. Then, the use of wear test machine test spray Friction properties between cladding layer and oil seal material. The experimental results show that the theoretically tribological properties is better in the same hardness conditions when the surface roughness is lower. The Ni-Cr-B-Si alloy powder and the ceramic powder are sprayed on the low carbon steel test piece, respectively. The alloy powder must be melted so that the spray coating material has great binding force and uniform distribution of particles with substrate. So that the hardness (HRC) of the material on the surface is increased by about 10 times. If the substrate uses AISI 5210 bearing steel, the spray coating structure will dense and close, which reduces the surface friction coefficient and roughness, and improve the abrasion resistance of the spray coating.
