AUTOMOTIVE COMPONENTS FORMED OF SHEET METAL COATED WITH A NON-METALLIC COATING |
摘要 |
<p>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.</p> |
