Diamond Grit Size Prediction in Surface Grinding Silicon Carbide

摘要

High hardness, chemical stability, attractive high temperature wear resistance, low density and strength at elevated temperature are the advantages of ceramics over other materials. These properties have made a number of components made of hard and brittle materials, typically represented by advanced ceramics gained applications in industrial sectors over the past two decades. Nevertheless the benefits due to the salient features of ceramic materials go along with some difficulties with machining in general because of their high values of hardness and very low fracture toughness as compared to other metallic materials and alloys. This paper presents an experiemntal study on identifying the diamond grit size and grinding condition that produced low surface roughness value, Ra and less micro-fractures on ground silicon carbide work-piece material.
