Abstract
Method of remanufacturing a component comprising: removing a damaged area of a cast iron component, the remaining component constituting a cast iron base; depositing molten particles on the cast iron base to form a pool of agglomerated molten particles, wherein the pool comprises aluminum and at least one of nickel, cobalt, chromium, silicon, or iron; cooling the pool to form a solid intermediate layer; and depositing solid particles on the solid intermediate layer to form an outer layer, wherein the solid particles comprise steel. Additionally, a component comprising: a cast iron base; an intermediate layer covering at least a portion of the cast iron base, wherein the intermediate layer comprises aluminum and at least one of nickel, cobalt, chromium, silicon, or iron; and an outer layer covering the intermediate layer, wherein the outer layer comprises steel.
