| Abstract: | In the paper, Metal Particle toughed FeAl_2O4-Al_2O_3-Fe composite coatings are fabricated by reactive plasma spraying technology in use of the exothermic reaction of Al-Fe_2O_3 system. The microstructure and performance of the composite coatings are studied. The results indicated that the microstructure of the composite coatings is with the bedded matrix phase FeAl_2O_4 and the horniness phase Al_2O_3, and the spherical Fe phase is distributed in the bedded coatings; and the ductility of the composite coatings is improved evidently . Its toughness excels that of Al_2O_3 ceramics coating by plasma spraying . In particular the coating has higher wear resistance compared with conventional alumina coating. |
