复合粉末材料是由两种或两种以上不同性质的固相物质颗粒经机械混合而形成的。组合复合粉末的成分，可以是金属与金属，金属（合金）与陶瓷金属（合金）与石墨等，范围广泛。通过不同组成或比例，可以衍生出各种功能不同的复合粉末。

按照复合粉末的结构，一般可分为包覆型、非包覆型和烧结型。目前应用较多的是包覆型和非包覆型粉末。

复合粉末使涂层具有多重功能，如硬质耐磨，减摩自润滑，可磨耗密封，耐腐蚀、抗氧化、绝热、耐高温，导电、绝缘、防辐射，抗干扰等功能。

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.
