Subsurface damage (SSD) in the polishing process of silicon carbide (SiC) ceramic presents one of the most significant challenges for practical applications. In this study, the theoretical models of SSD depth are established on the basis of the material removal mechanism and indentation fracture mechanics in the SiC ceramic polishing process.

Grinding of Tool Steel 4 2. Silicon carbide is an abrasive that is used pri-marily for grinding cast iron and austenitic stain-less steels, although it can also be used for hard-ened tool steels. It occurs in two main variants the black silicon carbide and a somewhat harder green variant, which is more brittle than the black material. 3.

Bonding of silicon carbide (SiC) based ceramic to other materials, such as metals, is of high importance for many advanced applications in fusion reactors, hot gas path turbine and rocket components, and chemical reactors. In this work, we demonstrate that the improvement of bond strength between SiC ceramic and metals is feasible by the employment of micro-column arrays (MCA).
