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. Une pièce usée, tel qu'un bloc moteur (30) ou une culasse de moteur (20), a au moins une dimension (12, 112) qui ne correspond pas à une spécification dimensionnelle pour la pièce. Un revêtement de pulvérisation thermique (13, 113) de FeAlSiC est appliqué pour reconstruire la dimension (12, 112). Le revêtement en excès (13, 113) est éliminé par meulage de façon à ce que le corps (11, 111) et le revêtement (13, 113) aient une seconde forme qui correspond à la spécification dimensionnelle pour le composant. Le revêtement (13, 113) a une structure cristalline ordonnée DO3 à dépôt d'oxyde d'aluminium stable qui produit une résistance à l'oxydation à environ 700°C.
