摘要

A turbine component is disclosed wherein a protective coat having oxidation resistance and abrasive property is formed on a part to be processed in the main body of the turbine component. An electrode which is composed of either a formed body made of a mixed material powder obtained by mixing an oxidation-resistant metal powder and a ceramic powder or such a formed body subjected to a heat treatment is used for formation of the protective coat. The protective coat is formed by producing a pulse discharge between the electrode and the part of the main body to be processed in an electrically insulating liquid or gas, thereby depositing, dispersing and/or weld-depositing the electrode material of the electrode onto the part to be processed.
