- Mechanism of Surface Cracking of Alumina Ring in Mechanical Seals. 2nd Report, Relationship between Thermal Stresses and Bending Strength.
抄録
In a previous paper, the authors proposed, on the basis of experiments and thermoelastic analyses, a mechanism of cracking characterized by deep through-cracks formed on the surface of an alumina ceramic ring of mechanical seals, and discussed preventive methods. That is, cracking is caused by thermally induced tensile circumferential stresses. Cracks originate at the edge of the seal face that is wet by the liquid being sealed, and propagate in the radial and axial directions through the alumina ceramic ring. However, bending strengths of alumina ceramics measured at room temperature were two to three times larger than the calculated values. In this study, the cause was investigated. As a result, it has been clarified that the strength of the alumina ceramic ring is decreased by boiling water and surface defects produced during the finishing process.
