Abstract
A multi-component metal coating consumable is provided in the form of a rod comprised of two different rod portions coaxially butt joined together in end-to-end relationship, one of said rod portions being a composite consisting essentially of at least 10% by weight of coarse particles of a refractory carbide dispersed through an alloy matrix, the other of said rod portions comprising a compatible alloy matrix structure, such that a welding or brazing rod is provided having two working ends, one to augment the other during the application of a hard and wear resistant coating to a metal substrate.
Claims14
As an article of manufacture, a multi-component metal coating consumable in the form of a rod comprised of two different rod portions coaxially butt joined together in end-to-end relationship to form a duplex rod,
- one of said rod portions being a composite consisting essentially of at least 10% by weight of coarse particles of a refractory carbide ranging in size from about 60 mesh to 3/8 inch substantially uniformly dispersed through a matrix alloy,
- the other of said rod portions comprising a matrix alloy structure compatible with the matrix alloy of said composite,
- such that a welding or brazing rod is provided having two working ends, one to augment the other when applying a hard and wear resistant coating to a metal substrate.
