Description
Summary:Zirconia-based ceramic articles produced by Klein and Syntek Keramik firms (Germany) for use as piston rings, cylinder liners and cylinder head plates in IC engines were investigated by X-ray, luminescent and ultrasound analyses. The density, porosity, ultimate bending strength at room temperature, Weibull's modulus, crack resistance and Young's modulus were determined in specimens cut from the articles and compared with the properties of domestic specimens based on Y-PSZ. The structure and composition were studied by SEM, petrography and X-ray and chemical analyses. The high-temperature strength was measured, and the structure of fractures caused by these tests was investigated by SEM. 5 refs.
