Molybdenum and molybdenum alloy metal temperature resistant materials, high strength can maintain a high

Molybdenum and molybdenum alloy metallic high temperature materials, the high temperature to maintain a high strength, but also has a high thermal conductivity and low thermal expansion coefficient, good thermal shock resistance, electrical conductivity and wear resistance, is widely used in aerospace field, including spacecraft solar  tungsten electrode  sheet molybdenum foil. However, molybdenum is relatively poor weldability and high temperature strongly oxidized, the oxide film is no protective effect, so the surface to be plated molybdenum modification. As the silver brazing with good  tungsten carbide inserts , usually silver plating surface of the molybdenum to improve the weldability and to reduce or prevent the oxidation of molybdenum. However, there is often a natural molybdenum oxide surface, the coating will interfere with adsorption, coupled between the molybdenum and silver alloy (solid solution) is difficult, therefore, molybdenum, silver plating surface is difficult, often plated directly adhered strong, coating quality is poor. Difficulties molybdenum plating solution approach is generally used in the pre-plating or strike plating layer deposited on the first surface of a thin metal (such as chromium, nickel, gold, rhodium, platinum, etc.), and then continue through the high temperature heat treatment plating process more cumbersome.
