A method for the production of metal - ceramic - composite materials as well as the use of the method for controlling the material properties of composite materials

摘要

so far, there have been highly porous ceramic materials with a liquid infiltrated so that the resulting product is mainly a metallstruktur. the metal ceramic material are the requirements for hardness, temperature resistance and wear resistance much below those values of the pure ceramic materials.now, the properties of the ceramic materials regarding flexural strength, toughness, e - module, hardness and resistance to wear while maintaining or increase compared to metallic materials superior properties such as hardness, temperature behaviour and wear resistance are improved.the ceramic material is $a consists of several layers, built with the thickness of between 10 and 15 m, and the average porenradius between 100 and 1000 nm with an open porosity of 5 to 14%, and gesamtporositu00e4t of 5 to 30%, and the molten metal in the porosity up to a restporenvolumen of 0.1 - 10%, based on the ausgangsporositu00e4t, is filled.$a it is preferred for the access to welds as welded or gelu00f6tete ceramic / metal structures.
