Influence of electrospark discharge parameters on roughness and microabrasive wear of steel 45 surface after ESA by TiC-based electrodes

Resumo

The influence of the parameters of electrospark discharge and electrode materials for electrospark alloying using the additives of boron-containing mineral raw material on the characteristics of microgeometry and microabrasive wear of the coating surface is investigated. It is found that the longer is the electrospark duration (from 20 to 80 μs), the higher is the surface roughness. The introduction of 1–2% of boron-containing raw material improves physicochemical properties of the alloyed layer, reduces the roughness, and increases the wear resistance.
