Effects of Grinding Parameters on the Processing Temperature, Crack Propagation and Residual Stress in Silicon Nitride Ceramics

Abstract: The surface/subsurface damage of engineering ceramics after machining has a great influence on the service performance of parts. In order to obtain a high grinding surface quality of engineering ceramics, and take silicon nitride ceramic as a research object, a series of grinding experiments were carried out. The effects of grinding parameters on longitudinal crack propagation depth and the surface residual stress of silicon nitride ceramics were analyzed by grinding experiments, and the residual stress at the… Show more

“…Unfortunately, present methods of laser-assisted machining impart cracks, phase transformation and chemical reactions, all of which highly disrupt microstructure. Lacking a regular crystalline lattice makes predicting crack magnitude, direction, and growth highly problematic [ 13 ].…”

“…This process involves the clearance of material by the scraping action of abrasive particles of diverse shapes, sizes, and geometries [12][13]. Three types of abrasive actions, namely friction, plowing, and shearing, occur during the interaction between the grinding wheel and the work surface, collectively influencing the efficiency of the grinding process [14][15].In this case, grinding encounters great challenges when used for silicon nitride ceramic processing [16][17]. The method often gives rise to the generation of surface and subsurface cracks [18].…”
