Abstract:
A downhole tool includes a circumferential band having a plurality of axially adjacent weld beads forming a wear resistant surface along a particular axial length of the tool and at least one circumferential multi-layer coating applied axially adjacent the band on either end. The multi-layer coating includes a first layer, exhibiting a first color, applied directly onto the tool surface, and a second wear-resistant layer, exhibiting a second color different from the first color, applied directly onto the first layer. The second layer wears or is removed by a certain amount, such that the first color of the first layer is revealed to indicate the extent of wear and/or that the tool should be removed from service and refurbished by applying a new wear-resistant coating.

Claim (Index 2):
The method of  claim 1 , wherein applying the first or second layers further comprises melting metal in a stream of oxyacetylene flame, electric arc, or plasma arc, and spraying metal droplets on the downhole tool surface at high velocities with a compressed-air spray gun.
