摘要：The method for producing cast parts with integrated components, which have ahigh surface hardness than the remaining cast part, comprises casting the integratedcomponent simultaneously with the remaining cast part, and subjecting the integratedcomponent 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 layerthickness 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 highsurface hardness than the remaining cast part, comprises casting the integratedcomponent simultaneously with the remaining cast part, and subjecting the integratedcomponent to a surface treatment after the casting process. The surface treatmentcomprises 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 layerthickness 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 compositionof 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 spheroidalgraphite.
