Development in Research and Application of Electro-spark Deposition Technology
Electro-spark deposition(ESD) is a new technique for repairing and strengthening on metal material surface. The ESD technique has the advantage of simple device, easy operability and wide application range. The repairing layer by ESD has higher wear resistance and much better corrosion resistance, which has good practical values and wide application prospects. The general principle and characteristics of the ESD method were introduced, and the development in research and application of the method was analyzed. The problems to be resolved for the technique were pointed out, and the development direction and suggestions on the intensive research and application of electro-spark deposition were proposed.
