Patent abstract
A degradation assembly has a carbide bolster brazed within a hole formed in a surface. The bolster has a substantially straight cylindrical portion mostly disposed below the surface and a top end and a bottom end. The top end narrows from the cylindrical portion with a substantially annular concave curve to a planar interface adapted for bonding to a carbide substrate and the bottom end narrows from the cylindrical portion to a stem which bottoms out on a geometry of the hole.
