Investigation of micro structural and mechanical properties of friction surfacing on low carbon steel by using stainless steel grades

Abstract

Friction coating is an advanced manufacturing process that has been developed and successfully marketed over the past decade. This process is used to prevent and resist corrosion in coatings and to regenerate worn structural elements. Currently, process parameters for producing new materials or substrate geometries are selected through experimentation, requiring long-term development work. The effect of transverse velocity on coating geometry, interfacial bonding properties, and mechanical properties is investigated. We changed the lateral speed, and the rotational speed and determined the axial load. Metallurgical studies were performed by light microscopy, scanning electron microscopy (SEM), and mechanical tests including bending and micro testing. The coatings are formed by cracks and have a fully austenitic structure. Speed is affected by bond integrity and film thickness. A solid metallurgical interface with 100% bond integrity has been developed for advanced food coatings. The higher the transverse speed, the thinner the layer, and the higher the bond strength.
