中文摘要：

喷洒的粒子金属性并且金属陶瓷电线被收集分析粒子的粉碎成原子状态在正在喷洒形成，金属性、陶器的涂层的微观结构和性质被调查并且比较。粒子尺寸分析器被用于确定的粒子尺寸。XRD， SEM 和光显微镜(OM ) 被用来分析阶段作文和粒子和涂层的微观结构。从试验性的结果，粒子特征的某差别在喷洒之间被建立涂层的金属性、陶器的 cored 电线，和微观结构和性质强烈取决于粒子行为。结果证明那 Fe-TiB2/Al2O3 合成涂层让为磨料潜在的高度穿应用。

英文摘要：

The sprayed particles of metallic and cermet wires were collected to analyze the atomization state of the particles in arc spraying forming, the microstructure and properties of metallic and ceramic coatings were investigated and compared. Particle size analyzer was used for quantifying particle size. The XRD, SEM and optical microscope（OM） were used to analyze the phase composition and microstructure of the particles and coatings. From the experimental results, some difference of particle characteristics was established between the spraying metallic and ceramic cored wires, and the microstructure and properties of coatings depend strongly on the particles behaviors. The result shows that Fe-TiB2/Al2O3 composite coating has a high potential for abrasive wear applications.
