Abstract

In this study, a dense Al2319/TiN composite coating was successfully prepared using cold spraying with mechanically blended powders. TiN particles were uniformly dispersed in the coating matrix with a volume fraction of 38.7 vol.%, which is higher than that of 32.7 vol.% in the powder blend. Compared with the pure Al2319 coating, the Al2319/TiN composite coating exhibits a significantly increased adhesive strength. The incorporation of the TiN particles increases the coating hardness from 106 ± 7.8 to 154.5 ± 18.9 Hv_0.2. In addition, compared with the pure Al2319 coating, the composite coating exhibits a significantly improved tribological performance. The results obtained in this work indicated that cold spraying is a promising process to fabricate Al alloy-based composite coatings.
