结果证明 ：在所定的工艺参数下 ，等离子喷涂层组织呈层片状 ，层间为机械结合界面 ；

The results show that structures of plasma sprayed coatings are lamella in shape, mechanical bond in interface regions.

相变点以上得到片层组织，片状组织的断裂韧性高于等轴组织。

The fracture toughness of lamellar microstructure is higher than that of equiaxial microstructure when deformed above the phase transition.
