Effect of TIG remelting on microstructure, corrosion and wear resistance of coating on surface of 4Cr5MoSiV1 (AISI H13)

This study aims at surface modification of the 4Cr5MoSiV1 (AISI H13) steel through the TIG (tungsten inert gas) remelting process. TIG remelting process was conducted using the major parameters, i.e. 250 A welding current and 120 mm/min welding speed (3.0 mm electrode diameter), under the protection of Argon. After remelting, X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS) were used to analyze...
