目前沐浴器材上常用材料多以黃銅或鋅合金為底材，並施以耐蝕的電鍍鎳/鉻，唯外觀顏色單調。為求沐浴器材外觀顏色之多樣化及防刮耐磨之強化，本研究擬結合電弧離子鍍及磁控濺鍍法於同一艙體，以電弧靶座來發射金屬鈦，以濺鍍靶座來發射銅金屬，於預電鍍鎳/鉻之銅基材表面被覆兼具色彩及抗菌之含銅氮化鈦陶瓷鍍層，進一步對其保固性做探討。研究結果顯示；相較於預電鍍鎳/鉻之黃銅基材，鍍膜表面硬度、耐磨性和耐蝕性皆高於預電鍍鎳/鉻之黃銅基材。隨著鍍膜中銅含量由0 at%增加至21.65 at%，鍍膜表面硬度及耐磨耗性略為下降，唯腐蝕電位從–371.76 mV 提高到–201.62 mV(vs. Ag/AgCl)，腐蝕電流密度則從0.612 μA/cm2 下降至0.489 μA/cm2。

Copper-zinc alloys, widely used for sanitary ware, were commonly pre-electroplated with corrosion resistant nickel/chromium, resulting in monotonic appearances. An arc ion plating (AIP)technique (for titanium emission) in combination with a magnetron sputtering (MS) source (for
copper emission) was employed in a single chamber to develop a color-controllable coppercontaining TiN antimicrobial coating in this study. Surface hardness, wear resistance and corrosion resistance were revealed as well. Experimental results showed that the copper-containing (Cu: 0 to
21.65 at%) titanium nitride coating distinctly gave rise to improved surface hardness, wear resistance and corrosion resistance of the alloy, comparing with the pre-electroplated Cu-35Zn substrate. Surface hardness and wear resistance slightly decreased at a higher copper content
though the alloy exhibited an increased corrosion potential (–371.76 mV to –201.62 mV vs.Ag/AgCl) and a decreased corrosion current density (0.612 μA/cm2 to 0.489 μA/cm2) in a sodium chloride solution.
