Silicon Nitride Applications in Modern Diesel Engines

Investigation of the effect of ZrO2 and ZrO2/Al2O3 additions on the hot-pressing and properties of equimolecular mixtures of α- and β-Si3N4

“…14. These results are in good agreement with those reported in literature [87][88][89]. Also, the presence of higher content of b-Si 3 N 4 with elongated grains enhances the fracture toughness due to the mechanism of crack bridging of the elongated grains [15,16,17,24,38,42,58,[73][74][75][78][79][80][90][91][92].…”

Dense and near-net-shape fabrication of Si3N4 ceramics

“…Silicon nitride component costs are generally dependent on the raw materials costs, material processing route and the product finishing costs, the latter often contributing ∼50% to the costs. In this area, the advantage is usually with the company that has already invested in the grinding and finishing equipment, and has gained the experience in making the components in production quantities [296]. Extensive research on silicon nitride had led to new areas of application such as ceramic bearings and ceramic springs capable of withstanding temperatures up to 1000 • C and applied to the fixtures used in brazing process, resulting in higher productivity [238].…”

Characterization and compositional study of a ZrO2 engineering ceramic irradiated with a fibre laser beam

“…Good thermal insulation and thermal properties have allowed engineering ceramics to be used for many components within a gas turbine engines. Engineering ceramics also reduce noise level in many engineering systems due to their acoustic damping capability and are also operational underwater due to their corrosive resistance and environmental stability [1][2][3][4][5].…”
