復合粉末材料是由兩種或兩種以上不同性質的固相物質顆粒經機械混合而形成的。組合復合粉末的成分，可以是金屬與金屬，金屬（合金）與陶瓷金屬（合金）與石墨等，范圍廣泛。通過不同組成或比例，可以衍生出各種功能不同的復合粉末。

按照復合粉末的結構，一般可分為包覆型、非包覆型和燒結型。目前應用較多的是包覆型和非包覆型粉末。

復合粉末使涂層具有多重功能，如硬質耐磨，減摩自潤滑，可磨耗密封，耐腐蝕、抗氧化、絕熱、耐高溫，導電、絕緣、防輻射，抗干擾等功能。

Composite powder material is two or more different nature of the solid phase particles by me chanical mixing of the composition of compound powder can be metal and metal, metal (alloy) and ceramics, metal (alloy) and graphite etc. a wide range. By different compost ion of proportion. can be dero portion can be derived from various functions of different composite powder.

According the structure of compound powder. Gene ally can be divide din to the coating, the coating and composite, the current application more is coated and non coated composite powder.

Composite powder coating has multiple functions, such as hard wear-resisting, anti-friction, self lubrication. Can wear. Corrosion resistance. Oxidation resistance, heat insulation, and heat conduction, radiating? protection. Anti-interterenec and other functions.
