Abstract:The progress of thermal spray coating of hard Cr instead of plating was described, including history of thermal spray coating technique, properties (wear resistance, corrosion resistance) of HVOF coatings, effects on the fatigue of substrates, cost and applications. Thermal spray coating has been widely used in aerospace, metallurgy, packaging, printing and paper-making industries instead of traditional plating technique. Owing to the advantage in preparing large-sized and thick coatings, and in low cost, thermal coating can be applied in other industries very fast.
Key words: thermal spray coating; hard chromium coatings; HVOF
