Abstract
In one aspect of the present invention, a degradation assembly comprises an inverted conical face formed in a top end of a metal body tapering towards a central axis of the metal body. A base end of a carbide bolster is adapted to be brazed to the top end of the metal body within the inverted conical face. At least one protrusion is formed in the inverted conical face and is adapted to control a braze thickness between the face and the base end.
