摘　　要：通过添加Ag、Zn、Pd、Ge等元素对Au-Cu合金进行合金化,采用正交试验研究了化学组成对玫瑰金颜色与耐人工汗液腐蚀性的影响。结果表明,在510~580 nm波长范围内,试验玫瑰金光谱反射率快速增加,继续增大波长后光谱反射率缓慢增加。当波长超过700 nm后,光谱反射率保持高位稳定,呈橙红至红色。此外,还发现玫瑰金化学组成不同,光谱反射率有差异。从提高亮度值L*和色度指数a*方面,Au85玫瑰金的优化化学组成(质量分数,下同)分别是Ge为0.2%、Ag为2%、Pd为0.3%、Zn为0.6%和Ge为0、Pd为0.3%、Zn为0.6%、Ag为2%,而从提高在人工汗液中的阻抗和自腐蚀电位方面,Au85玫瑰金化学组成的优化匹配是Ag为2%、Pd为0.3%、Zn为0.6%。因此,合金元素对Au85玫瑰金的颜色和耐蚀性的影响规律不完全一致,在确定靶材化学组成时需综合考虑。Ag,Zn,Pd and Ge were added for multicomponent alloying of Au-Cu alloy,and influence of chemical compo⁃sition on color and corrosion resistance to artificial sweat of rose gold were investigated through orthogonal test.The results indicate that the spectral reflectance of rose gold is increased rapidly in the wavelength range of 510~580 nm,which is then increased slowly with the increase of wavelength.When the wavelength exceeds 700 nm,the spectral reflec⁃tance remains high and steady,presenting orange-red to red.Moreover,the spectral reflectance varies with chemical com⁃position.In aspect of improving L*and a*,the optimal chemical composition of Au85 rose gold is 0.2%Ge,2%Ag,0.3%Pd,0.6%Zn and 0Ge,0.3%Pd,0.6%Zn and 2%Ag,respectively.From the perspective of improving the imped⁃ance and self-corrosion potential in artificial sweat,the optimal maching of Au85 rose gold is 2%Ag,0.3%Pd,0.6%Zn.Therefore,the influence of alloying elements on color and corrosion resistance of Au85 rose gold is not exactly consis⁃tent,and a comprehensive consideration is required with determining the chemical composition of target.
