Laser treatment for corrosion prevention of electrical contact gold coating
Applied Surface Science(2002)
摘要
The materials used in electrical contact applications are constituted of a copper alloy (brass or bronze) electroplated with two coatings, a nickel layer (diffusion barrier) and a gold layer (corrosion barrier). There are some pores in the nickel and gold layers leading to corrosion of the underlying layers.
