Wear of metal matrix composites – Basudev Aryal

Abstract:

Abrasive wear is one of the most frequent and extensive wear an agricultural tool goes through a tool with high resistance to abrasive wear is preferred at the lowest cost possible. To meet the requirement and to produce the tools which last long and is cost effective, manufacturer considers the criteria such as required wear resistance, hardness and toughness. Agricultural tool wear resistance depends on the change of structure with the applied heat treatment, chemical composition used in the tool material, their hardenability and physical and mechanical of properties of the soil.Materials were tested and evaluated for their abrasive wear resistance in the laboratory using the dry rubber wheel testing machine (ASTM G-95). Vicker’s hardness test is performed to determine the hardness property of the materials.Microstructure of worn surfaces were investigated with the aid of microscope and the result shows that the materials possess higher wear resistance with increase in boron content which is in correlation with the materials hardness. …víceméně
