ABSTRACT:
A method of hard coating a surface with carbide. A first step involves positioning a temporary membrane a pre-selected distance from a surface of a work piece to be hard coated to create a insertion gap which is accessible from an upper end. A second step involves filling the insertion gap with carbide pieces, sized to fit the insertion gap in a selected orientation, by inserting the carbide pieces from the upper end of the insertion gap and allowing them to drop into the insertion gap by force of gravity. A third step involves filling spaces between the carbide pieces with bonding powder by inserting the bonding powder into the upper end of the insertion gap. A fourth step involves heating the powder until the carbide pieces are bonded to the surface. A fifth step involves removing the temporary membrane.
