ABSTRACT:
An abradable seal coating for application to one of a pair of members having relative rotational movement and its method of manufacture are described.
The abradable seal coating comprises a two phase composition consisting of a first phase of a metallic alloy matrix of approximately 88% aluminium - 12% silicon, and a second phase of an organic dispersoid material. The first and second phases are codeposited onto a substrate in the ratio 80:20 respectively.
The two phases are modified after codisposition onto the substrate by heat treating at a temperature of 450.degree. C. for about sixteen hours. The heat treated coating can be used at elevated temperatures and has improved abradability whilst maintaining its integrity.
