Abstract
Method of metallizing a ceramic substrate so as to obtain on this substrate weldable metallized zones or areas usable at a high temperature, characterized by depositing on a ceramic substrate, an ink including cobalt oxide and forming a hooking layer by forming a compound between the ceramic and cobalt oxide, under an oxidizing atmosphere, and, reducing at about 1,100.degree. C., the oxide superficially so as to obtain a cobalt metal layer and metallized zones or areas weldable by a method known per se.
Claims6
A method of metallizing an alumina substrate to obtain weldable metallized zones or areas thereon usable at a high temperature, said method consisting essentially in the sequential steps of:
- (a) depositing on said substrate an ink composed of a dispersion of a cobalt oxide in collodion,
- (b) forming a compound between said substrate and cobalt oxide, in an oxidizing atmosphere, at about 1,100.degree. C., and thereafter
- (c) reducing the oxide superficially to obtain a cobalt metal layer on which weldable metallized zones or areas may be deposited.
