Abstract

Microstructure and properties of structural steel layers subjected to overlay welding utilizing materials powder as well as elect of hardness and microstructure on adhesive wear are investigated. Materials powder spread over the Ct3 steel surface or mixed with the AMS1 flux was melted in low carbon wire Cb 08 arc. The powder of alloying elements Cr, Mo, W, Co and Fe-60%V, Fe 70% Mn, B4C, WC-8%Co and of secondary raw materials (glass, grinding wheels, hard metal plates) was used for overlay welding. Depending on the used powder composi tion and heat treatment, alloyed, hard (to 68 HRC) layers, which wear resistance is similar to standard tool steel, are obtained.
