Composite Material Made of Metal and Ceramic, and Method for Production Thereof

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a novel composite material made from metal and ceramic, where the metal and/or metal-ceramic component is present as coarse grains (500 µm to 10,000 µm) making up more than 5% by weight. The composite achieves enhanced thermal, mechanical, and chemical properties by optimizing the mixture and structure of different grain sizes and types, and covers methods for preparing this material. The invention enables the creation of parts and components for use in high-temperature and harsh environments.
