Abstract
A method of remanufacturing an engine block includes providing an engine block having at least one cylinder bore with a bore interior surface having a thermal spray coating deposited thereon, determining at least a portion of the thermal spray coating is out of specification, performing a laser texture ablation (LTA) process on the thermal spray coating to remove at least a portion of the thermal spray coating and leave a textured surface, and performing a thermal spray coating operation by spraying an additional thermal spray coating on the textured surface, to thereby prevent scrapping of the engine block with the out of specification thermal spray coating.
