<p>The method for producing cast parts with integrated components, which have a high surface hardness than the remaining cast part, comprises casting the integrated component simultaneously with the remaining cast part, and subjecting the integrated component to a surface treatment after casting process. The surface treatment comprises a surface hardening with a hardness of larger than 50 harmonic related carrier (HRC) and a surface coating with a hardness of larger than 50 HRC, and has a layer thickness of 0.1 mm. The surface treatment is produced by high-speed flame spraying. The method for producing cast parts with integrated components, which have a high surface hardness than the remaining cast part, comprises casting the integrated component simultaneously with the remaining cast part, and subjecting the integrated component to a surface treatment after the casting process. The surface treatment comprises a surface hardening with a hardness of larger than 50 harmonic related carrier (HRC) and a surface coating with a hardness of larger than 50 HRC, and has a layer thickness of 0.1 mm. The surface treatment is produced by high-speed flame spraying, and is carried out with a tungsten carbide containing metal powder with the composition of tungsten carbide-nickel-chromium-boron-silicon 67-33 (WC-NiCrBSi67-33). The cast part with the integrated component is produced from a cast iron alloy with spheroidal graphite.</p> |
