✦ Synopsis

Research and development work that has been done by Sulzer Metco has led to 'abradable' coatings which are now being used successfully in turbine-engine applications for clearance-control seals of gas leakage over the tips of the blades. This feature, based on an article by Sulzer's Mitchell Dorfman, Ulrich Erning and James Mallon, which appears in StiIjer Technical Review, briefly looks at the underlying technology which, among other reasons, has been developed in response to customers' concerns over increasing demands on turbine operating temperatures and output efficiencies.
