REMANUFACTURED COMPONENT AND FEALSIC THERMAL SPRAY WIRE FOR SAME

A used component such as an engine block (30) or engine head (20), has at least one dimension (12, 112) that does not match a dimensional specification for the component. A thermal spray coating (13 , 113) of FeAlSiC is applied to build up the dimension (12 ,112). The excess coating (13 ,113) is mil...

Beschreibung
Zusammenfassung:	A used component such as an engine block (30) or engine head (20), has at least one dimension (12, 112) that does not match a dimensional specification for the component. A thermal spray coating (13 , 113) of FeAlSiC is applied to build up the dimension (12 ,112). The excess coating (13 ,113) is milled off so that the body (11, 111) and coating (13 , 113) have a second shape that matches the dimensional specification for the component. The coating (13 ,113) has an ordered DO3 crystal structure with a stable aluminum oxide scale that produces oxidation resistance at about 700° C.
