Publication number: 20060003885Abstract: The invention relates to cast parts which contain at least 87 wt. % silicon nitride and up to 13 wt. % of an additive combination comprised of Al2O3 and Y2O3. The initial composition of the mass formulation starts with Y2O3/Al2O3 ratios of less than 1.1, preferably with Y2O3 Al2O3 ratios of 0.2 to 1.09. 1% to 20% of the Y2O3 portion can thus be substituted by an additional element of the group IVb of the periodic table or by the oxide thereof. The cast parts can comprise up to 1.0 wt. % HfO2 and/or ZrO2. Said cast parts preferably have a thickness >98% of the theoretic thickness. At room temperature, the bending strength of the inventive cast parts amounts to ?1100 MPa and amounts to ?850 MPa at 1000° C. The inventive cast parts correspond to the formula Si6-zAlzOzN8-z. The degree of substitution z thus amounts to 0.20 to 0.60, preferably from 0.22 to 0.54, especially from 0.3 to 0.35.Type: ApplicationFiled: April 12, 2005Publication date: January 5, 2006Inventors: Guenter Riedel, Hartmut Kruener, Matthias Steiner, Peter Stingl

Patent number: 6779267Abstract: A method for increasing the wear-resistance of a work piece involves connecting the work piece to a non-formable core material having a greater hardness than that of the work piece material. In order to improve the connection while simultaneously reducing the costs, the core material is connected in a form-fitting manner to the work piece by means of cold extrusion or hot extrusion of the work piece material.Type: GrantFiled: August 10, 2000Date of Patent: August 24, 2004Assignees: GeramTec AG Innovative Ceramic Engineering, UKM Umformtechnik und Kraftfahrzeugkomponenten MeiBen GmbHInventors: Gerd Meier, Carsten Rubner, Klaus Rubner, Peter Stingl, Helmut Radke, Steffen Tempel, Dietmar Leuteritz
