AUTOMOTIVE COMPONENTS FORMED OF SHEET METAL COATED WITH A NON-METALLIC COATING

An automotive component (20) is manufactured by depositing a non-metallic coating (24) on a surface of a steel blank (26) before hot stamping the steel blank (26). The non-metallic coating (24) is typically applied by physical vapor deposition. The non-metallic coating (24) is formed of one to three...

Zusammenfassung:	An automotive component (20) is manufactured by depositing a non-metallic coating (24) on a surface of a steel blank (26) before hot stamping the steel blank (26). The non-metallic coating (24) is typically applied by physical vapor deposition. The non-metallic coating (24) is formed of one to three layers (32) each having a different composition. The non-metallic coating (24) includes at least one of silicon and carbon, and can also include oxygen, nitrogen, ceramic compounds, and carbides. The total thickness of the non-metallic coating (24) is less than 300 nm. A metallic coating (30) can be applied to the steel blank before the non-metallic coating (24). The non-metallic coating (24) provides numerous advantages, including reduced scaling during the hot stamping process. L'invention concerne un composant automobile (20) fabriqué en déposant un revêtement non métallique (24) sur une surface d'un flan (26) en acier avant estampage à chaud dudit flan (26) en acier. Le revêtement non métallique (24) est typiquement appliqué par dépôt physique en phase vapeur. Le revêtement non métallique (24) est formé d'une à trois couches (32) dont chacune présente une composition différente. Le revêtement non métallique (24) comprend du silicium et / ou du carbone, et peut également comprendre de l'oxygène, de l'azote, des composés céramiques et des carbures. L'épaisseur totale du revêtement non métallique (24) est inférieure à 300 nm. Un revêtement métallique (30) peut être appliqué au flan en acier avant le revêtement non métallique (24). Ledit revêtement non métallique (24) présente de nombreux avantages, notamment un écaillage réduit au cours du processus d'estampage à chaud.
