摘要
先在18KW金、黄铜或玻璃基材表面镀SiO_(2)底膜,再真空蒸镀防指纹(AF)膜。研究了SiO_(2)底膜镀覆时间和基材表面粗糙度对AF膜疏水性、疏油性、耐蚀性和耐摩擦性能的影响。结果表明,首饰金属基材不宜直接镀覆防指纹膜。随着SiO_(2)底膜镀覆时间的延长,首饰表面亮度逐渐下降,色度逐渐增大,防指纹膜的水(油)接触角先增大后减小,耐人工汗液腐蚀性能、耐酸性盐雾腐蚀性能、耐工业橡皮摩擦性能以及耐酒精绒布摩擦性能均先改善后变差,较佳的SiO_(2)底膜镀覆时间为150 s。基材表面粗糙度也会影响防指纹膜的疏水(油)性,采用240#砂纸打磨基材时所得防指纹膜的接触角显著高于采用布轮抛光时。
SiO_(2) films were deposited as an underlayer on different substrates i.e.18KW gold alloy,brass,and glass by magnetron sputtering prior to deposition of anti-fingerprint(AF)coating via vacuum evaporation.The effects of deposition time of SiO_(2) underlayer and roughness of substrate on the hydrophobicity,lipophobicity,corrosion resistance,and friction resistance of AF coating were studied.The results showed that the metallic substrate of jewelry should not be deposited with AF coating directly.With the extending of deposition time of SiO_(2) underlayer,the jewelry was decreased in brightness and increased in chromaticity gradually,while the water and oil contact angles of AF coating were increased initially and then decreased,and the resistance of AF coating to artificial sweat corrosion,acid salt spray corrosion,industrial rubber friction,and alcohol flannelette friction were improved initially and then became worse.The suitable deposition time of SiO_(2) underlayer was 150 s.The surface roughness of jewelry metal substrate also had an impact on the hydrophobicity and lipophobicity of AF coating.The contact angle of AF coating deposited on jewelry surface polished with 240#sandpaper was significantly higher than that on the one polished with cloth wheel.
