The concept, development background and the present applications of functionally gradient materials (FGMs) are introduced. Some spraying methods to fabricate FGM coatings, such as plasma spraying, flame spraying, high velocity oxy-fuel (HVOF) spraying and detonation flame spraying are reviewed. The research emphases and prospects of the technologies are put forward.
