摘要
Abstract
The influences of Ge on the microstructure and properties of 925Ag silvers,such as cold working performance,anti-electrochemical corrosion,anti-tarnishing of sulfuration and oxidation,were studied by means of optical microscopy,hardness test,potentiadynamic polarization technique and color analysis.The results show that 925Ag alloy has better comprehensive performance when the content of Ge in silvers is between 0.2％ and 0.8％,and when adding 0.5％ Ge,925Ag alloy is better in as-cast hardness,working performance,anti-electrochemical corrosion and anti-tarnishing.关键词
