Review on Research and Development of Abrasive Scratching of Hard Brittle Materials and Its Underlying Mechanisms

Hard brittle materials such as ceramics and crystals are commonly utilized in various industries, including information technology, mechanical engineering, semiconductors. These materials, known for their high brittleness hardness but low fracture toughness, pose challenges efficient high-quality machining. Current abrasive machining techniques involve rough grinding, fine polishing processes, with the latter being most time-consuming accounting over half of total time. Improving processing parameters grinding can increase efficiency, reduce surface subsurface damage, improve workpiece quality, ultimately reducing This paper explores scratching hard examining nucleation propagation cracks causing underlying mechanisms. The research provides suggestions enhancing efficiency ensuring quality materials.
