Characterization of dry-sliding wear of HVOF coatings made of Fe3Al powders reinforced with sub-micrometer TiC particles produced by combustion synthesis

Alloys used to fabricate water turbines for power generation are subjected to cavitation wear in an environment propitious to corrosion. Refurbishing by build-up welding of such gigantic infrastructures is time consuming and costly. Therefore, efforts are being deployed to develop coatings that woul...
