Experimental investigation of ultra-assisted electrode sparkles depositing process

Ultra-assisted electrode sparkle depositing(UAESD) developed based on the traditional electrode sparkle depositing(ESD),and better coating could be achieved when ultrasonic vibration was adopted in the ESD technology.In this paper,UAESD was realized by the supersonic vibration of the body.The results showed that formation technological parameters were enlarged by supersonic vibration,and the better surface topography was achieved.The deposition efficiency increased 30%,microhardness increased 10% while the grain size decreased 24.18% under the influence of the supersonic vibration.With the UAESD process,heat affected zone was enlarged and the microhardness at those points was increased.Moreover,the corrosion resistance of the bond was enhanced.
