Study on the Properties of Silver Plating on A6061 Aluminum Alloy

Abstract

This article presents the properties of the silver plating on A6061 aluminum alloy. The structure, chemical composition, phase composition, thickness and corrosion durability of the plating are determined by scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), X-ray diffraction, corrosion current measurement, frost acceleration and hygrothermal test. The results show that the silver plating has good corrosion resistance, is not blistered, remains white, light, no appearance of rust and other abnormalities. These parameters meet the technical requirements laid out for resonator of ultra -high frequency filter.
