Wear Behavior of Fe-Cr-V based Hard Facing Alloy on ASTM A105 Steel
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2019, Vol 9, Issue 4
Abstract
Dynamic contact surfaces life rate depends on various factors, majorly it is influenced by wear between contact surfaces. Hard facing is one of ancient technique used to improve mechanical properties, majorly surface properties of contacting surfaces and reduces the internal stress. The present investigation is on the influence of multilayer hard facing on abrasive wear compared to monolayer hard facing. Composition of Fe with the addition of chromium and vanadium based hard facing coatings are deposited on ASTM A 105 STEEL in form of single layer and multilayer depositions by using Shielded metal arc welding. Microstructure investigations stated that homogenous dendrite colonies are formed on both layers. The monolayer exhibited poor abrasive wear resistance as compared to multilayer depositions and more surface cracks and voids are formed. The wear rates of depositions are investigated in the form of volume loss and mass loss. Increase in content of carbon can increase the hardness and the binding strength of the layers and reduce the effect of abrasive wear.
