Nylon powder is a kind of thermoplastic powder and has a wide operating temperature, good physical properties and good wear resistance, small friction coefficient, etc [1].Nylon powder melting, good flowing property, especially the low melting point of nylon powder, because good flowing property and various metal has good adhesion force, used for metal surface coating, can keep the metal hardness, rigidity, and can obtain the characteristics of nylon, and can run less or do not add lubricating oil (oil or water);The coating can undertake all kinds of mechanical processing, size does not conform to the requirements or surface as a result of insufficient level off, the car, the plane processing can be performed.Nylon powder mainly PA1010 powder, PA1010/6 powder, 66/6 PA1010 / powder, modified nylon PA11, PA12 and epoxy resin composite powder, etc., has been widely used in powder coating, filler, adhesive, medicine and cosmetics fields [2], and gradually to the decoration, the mute shock absorption, etc.
