In this study we studied the influence of post heat treatment of thermally sprayed WC-Co coatings on coating microstructure, phase structure and wear resistance. The coatings were prepared from two different spray powders by detonation gun process, with two different spray conditions. The as-sprayed coatings showed very different microstuctures and wear properties. After heat treatment, the coatings showed very similar good wear performance, although the phase structures showed large differences. Abstract only; no full-text paper available.
