Abstract
Surfaces subject to wear and corrosion can have their service life increased by being coated with a composite coating applied by the electric arc thermal spray process using at least one titanium feed wire, optionally pre-nitrided, a second wire of a different metal, metal alloy ceramic or intermetalic compound and nitrogen in the arc spray gun.
