| Abstract: | In order to study the property of Al2O3-13%TiO2 nano-structured plasma sprayed coatings,parameters of plasma spraying were optimized by orthogonal experiment design.The coatings,which were deposited with nanometer-sized and micron-sized Al2O3-13%TiO2 powders by optimized parameters,were tested by instruments.The microscopic structure was observed by metallographic microscope and scanning electron microscope(SEM).The special area of nano-structured Al2O3-13%TiO2 coatings is analyzed by electron energy spectrum. |
