Kovar alloy polishing mainly comprises three types of mechanical polishing, electrochemical polishing and chemical polishing, and the chemical polishing is a mainstream process of industrial production due to the reasons of simple equipment, simple and convenient operation, low cost and the like. The classical chemical polishing solution is a triacid polishing solution consisting of sulfuric acid, phosphoric acid and ammonium molybdate, has excellent polishing effect, and ensures that the brightness and the flatness of the surface of the kovar alloy can meet the requirements.
