CERAMIC MATERIAL, PRODUCTION, USAGE AND A LAYER OF THE SAME

摘要

The invention relates to a ceramic material (1) which is suitable for coating a body (9) using a thermal spraying method and which has a thermal longitudinal expansion coefficient that can be adapted to that of a metal. The ceramic material (1) contains between 10 and 95 wt. % MgAl2O4, between 5 and 90 wt. % MgO, up to 20 wt. % Al2O3 and a residue of conventional impurities. The material has grains (3) of MgO which are embedded in a MgAl2O4 matrix (2).
