Abstract

The application of rapid omnidirectional compaction (ROC) processing to plasma-sprayed tantalum coatings in order to produce dense wear-resistant tantalum carbide coatings on a variety of predensified ceramic substrates is reported. Substrate materials included aluminium nitride, silicon carbide, silicon nitride, and WC-6Co. In particular, the phase chemistry which evolves during ROC processing, the surface morphology of the coating as-deposited and after ROC processing, and the erosive wear resistance of the coatings, are discussed.
