Abstract
A debarking knife includes a plate having at least one sharp debarking edge delimited by a leading face and a trailing face. The leading face is reinforced by an anti-abrasion hard surface coating having better anti-abrasion qualities than the substrate forming the plate. The anti-abrasion hard surface coating is preferably a mixture of grains of fused tungsten carbide bound by an Ni/Cr/B/Si alloy, the whole being brazed to the substrate using a laser beam.
