Patent

CA 2477644

A method for applying a wear-resistant material to a rock bit is disclosed that includes depositing a coating on a selected area of the rock bit, applying a heated wear- resistant material using a laser assisted cladding apparatus to a selected portion of the rock bit, wherein the coating is selected to have material properties to prevent significant bonding between the heated wear-resistant material and the coated area of the rock bit.

Divulgation d'une méthode servant à appliquer sur un trépan un matériau résistant à l'usure. La méthode inclut le dépôt d'un enduit sur une surface précise du trépan et l'application d'un matériau chauffé résistant à l'usure sur une autre partie du trépan à l'aide d'un appareil de gainage assisté au laser, où le dépôt est choisi en fonction de propriétés matérielles destinées à empêcher le matériau chauffé résistant à l'usure et l'enduit du trépan de se lier.
