Characteristics of ($AI_2$ $O_3$40％$YiO_2$)NiCr thermal sprayed composite coatings

($AI_2$ $O_3$40%$YiO_2$)NiCr 복합용사피막의 특성

The multi function sprayed coating is used for direct-heating, wear resistance and high bonding strength. The merits of surface direct-heating coatings are short warming time, low power consumption and better wear resistance that can be used in many organization parts. In this study, the surface direct-heating and wear resistance can be improved by spraying the proper materials on the surface $Al_2$O$_3$40%TiO$_2$ powder and Ni-20%Cr powder that had the properties of conduction and high wear resistivity are used in order to improve wear resistance, electrical properties and bonding strength.
