ABSTRACT
The effects of process parameters on coating formation and coating properties were investigated using a fused and crushed Ti $O_2$powder by the Taguchi method and L$_{9}$(3$^4$) orthogonal array. The Taguchi analysis was conducted through the results of the coating properties affected strongly by plasma spraying parameters and Ti $O_2$powder was sprayed on Ti-6Al-4V alloy substrate. The coating properties were characterized by thickness, microhardness, porosity and surface roughness using optical microscopy, image analyzer and surface roughness tester respectively. An observed optimum condition of plasma spraying process could be found for potential use as a bioceramic coating.Ѐ䔀Ѐ䔀Ѐࠀ䄀厧Ā厧Ā̀￿￿郧ﺖ⨀聰㘂낹﾿缀偫—⨀⁉—⨀—⨀Ȁj—⨀—⨀Ā 砨—⨀—⨀开Āᣪﺖ⨀䂥ﺖ⨀ሀ碤ﺖ⨀ሀ䂥ﺖ⨀ሀ㑧잖⨀ࠀ㤝ᦨĀᦨĀ̀￿￿㑧잖⨀厧Āᢦﺖ⨀墦ﺖ⨀磬ﺖ⨀硠ﺖ⨀ﺖ⨀ԀĀࢦﺖ⨀Ѐ褎돀ハﺖ⨀塨
