Abstract
A process is provided for producing an abrasive coating on a substrate surface by applying a bond coat by low pressure plasma spraying and anchoring to the bond coat abrasive particles by electroplating and embedding the particles into an oxidation resistant matrix by entrapment plating.
Claims11
An abrasive coated substrate comprising:
- a Ni or Co based superalloy substrate;
- a low pressure plasma sprayed bond coat;
- and
- a layer of entrapment plated abrasive particles in a metal matrix.
