Carbide Coatings on Hot Working Steel (Cr High Alloy H-13 Steel) By Detonation Gun Process: A Review
In this study, WC-Co and Cr3C2-NiCr coatings were deposited on H-13 hot forging steels by Detonation Gunspray process and analysed with regard to their performance under abrasive wear conditions. Dry Sand Abrasive Wear
Testing Machine was used for wear tests, and the effects of three parameters namely: speed (rpm), load and composition, on
abrasive wear of the material was investigated. The Detonation gun-sprayed WC-Co and Cr3C2-NiCr coated H-13 steel
showed better abrasive wear resistance in comparison with their uncoated counter parts. It may be due to the higher hardness
and toughness as a result of – D-gun sprayed WC-Co and Cr3C2-NiCr coating in comparison with the uncoated H-13 steel.
