摘　　要：镀金制品采用镀镍防扩散层可以防止底层的铜与金层的相互扩散。西欧国家与人体直接接触的金属消费品规定了镍释出率和标准。Intermediate nickel deposit may be used as barrier coating to prevent mutual diffusion of copper (alloy)base with gold top coating.Since the release of nickel ions form human-skin contacting consumer goods is restricted by standards and regulations in most western European countries. substitute barrier coatings for nickel is suggested.
