Deposition of black-colored films whose mayor component is gold using the RF ion plating method was investigated, and the results were evaluated. Au-Al alloys were used as the evaporation source material. AlN was first produced by the reactive ion plating method using nitrogen gas as the reactive gas and the evaporation conditions of Au and AlN composite black films were then studied. Black Au-AlN composite films with high corrosion resistance were obtained on the substrate under conditions of an RF power of 150W, a bias voltage of 500V and an evaporation rate of 36nm/min. To examine the potential for commercial use, the same lustrous black composite films were produced on post earrings (K18 and K14) under the same conditions as mentioned above. These results open up new possibilities for design of ornaments and production of value-added goods.
