Microstructure,Mechanical and Oxidation Characteristics of Detonation Gun and HVOF Sprayed MCrAlYX Coatings

摘要：

　　The microstructure, mechanical and oxidation characteristics of detonation gun and HVOF sprayed MCrAlYX coatings were investigated by means of SEM, XRD, micro-hardness and oxi dation test, etc.The results showed that MCrAlYX coatings prepared by detonation gun and HVOF spraying exhibited lamellar and uniform microstruc ture, respectively.The detonation gun sprayed coat ing exhibited a much lower porosity than the HVOF sprayed coating.The micro-hardness of the MCrAlYX coatings prepared by detonation gun and HVOF spraying was all around 900Hv and the deto nation gun sprayed MCrAlYX coating exhibited a better oxidation resistance than the HVOF sprayed coating.
