Abstract
Nickel-aluminium coating was deposited on AISI 304 stainless steel by HVOF process. The coating was characterised by scanning electron microscope and optical microscope. The surface hardness, surface roughness, thickness and fracture toughness value of the coating was determined. Slurry erosion testes were carried out on both the coated and uncoated samples by varying the impact angles at 30°, 60° and 90°, and their slurry erosion behaviour was studied. The coated samples exhibited 3.5 times, 1.9 and 1.04 times more resistance to slurry erosion at 30°, 60° and 90° impact angle, respectively, than the uncoated bare steel.
