摘要

本研究主要探討以粉末燒結法製備鈦多孔結構塗層，使用4種不同粉徑以及型態的鈦粉末進行搭配，在Ti-6Al-4V ELI基材上製備多孔結構。再對多孔塗層進行表面形貌、化學成分、塗層微結構、粗糙度、以及機械強度進行分析。

研究結果顯示，純鈦粉末在基材上經塗佈及燒結製程後，可製備高孔隙率之塗層。而透過不同粉徑及型態的搭配，可發現使用不規則粉末進行塗佈之孔隙率較圓珠粉末高，且上層使用不規則粉末可有效增加其粗糙度，而上層使用相同粉徑之不規則粉末可獲得相近的粗糙度。最後，成功於Ti-6Al-4V ELI基材上產生多孔結構塗層，而使用不規則粉末進行塗佈將可望增進試件表面之孔隙率、孔徑尺寸與粗糙度。

The purpose of this study is to fabricate porous titanium structure coatings by powder metallurgy. To fabricate porous titanium structure coatings was used four types titanium powder include beads and irregular powder on Ti-6Al-4V ELI substrate. The coating surface morphology, chemical composition, thickness, porosity, pore size, roughness and mechanical properties of the sample were characterized via various techniques.
The research results show that using pure titanium powder coating on Ti-6Al-4V ELI substrate can fabricate high porosity coating. Through different powder diameters and types, the porosity of coating with irregular powder is higher than beads, and using irregular powder on the upper layer can effectively increase its roughness, and using same diameters powder can obtain similar roughness. At the end, Porous structure coating was successfully applied to Ti-6Al-4V ELI substrate, to enchancing their porosity , pore size, and roughness.
