Research on the Performance of Ultrasonic Vibration Assisted Electrical Discharge Surface Modification Layer
Ultrasonic vibration assisted electrical discharge surface modification was studied in the paper. The influence of ultrasonic vibration amplitude and frequency on the modification layer performance, such as surface roughness, sectional morphology, micro hardness and wear resistance was investigated. Experimental results show that ultrasonic vibration assisted electrical discharge surface modification can improve surface roughness and make the melting material well-distributed. The surfaces have higher micro hardness and wear resistance when the tool electrode is assisted with ultrasonic vibration.
