Abstract
At present, coatings are mostly produced by CVD, PVD methods, plasma, and detonation spraying. Molten salts for coatings deposition are also becoming highly attractive. They provide wide possibilities for coating production of hafnium by electrodeposition, electrochemical synthesis, and precise surface alloying. Consideration is given to all these methods. The production of heat-resistant coatings from hafnium and niobium-hafnium alloys, and the electrochemical syntheses of copperhafnium solder and HfB2 coatings are also discussed.
