Abstract

The push-off test for measuring the bonding property between surfacing layers and steel base metal was developed after referring to and analysing relevant literature. The push-off test specimens were prepared with surface layers of austenite steel, alloyed steel strengthened by niobium carbide, and high-chromium, hyper-eutectic alloyed, cast iron on a 45 steel base metal by applying a consumable metal electrode arc surfacing welding process with three types of self-shielding, flux-cored, welding wires. The chemical compositions and microstructure of the final product were studied. The bonding strengths of 316, 241, and 60 MPa between three types of surfacing layers and the 45 steel base metal were obtained, after the push-off test. Additionally, the fracture path and fractograph characteristics were observed and determined.
