METHOD AND APPARATUS FOR SURFACE MODIFICATION OF METAL PARTS

摘要

A method of modifying surfaces of metal parts is disclosed. The method comprises a step of melting an area of metal surface by high-density energy irradiation -- Step 1; a step of sensing the temperature (t) of the melted area -- Step 2: and steps of carrying out the build-up welding by using a wire (8) containing heatresistant alloying element(s) (25) -- Steps 3, 4 and 5.
