Production of Composite Powder by Fluidized-bed Granulation Process and Evaluation of Sprayed Coating Properties

摘要

Ceramic / plastic composite powder (ceraplas powder) has been produced by Fluidized-bed granulation process (FG process) by varying the binder. Alumina (Al_2O_3) has been used as ceramics and Polyphenylene-sulfide (PPS) has been used as plastics. PPS has high heat and corrosion-resistant performance. Moreover, sprayed composite coatings have been evaluated by the observation of the coating microstructure, the thermal analysis, the corrosion test and the abrasive wear test. It has been recognized that sprayed composite coatings produced by FG powde have high corrosion-resistance and good wear resistance.
