Hardfacing is a welding process used to apply a material with increased hardness, ductility, erosion-resistance, and/or corrosion-resistance relative to the base (parent) material. It is also commonly referred to as cladding or hardsurfacing. Due to hardfacing materials improved properties, a part’s service life is prolonged. Hardfacing can be applied to new part to offer a value-added feature, or it may also be applied to repair previously deteriorated parts.
