    摘要: A method is provided for coating a surface of an Fe-based, hardenable sintered, sinter-forged or forged component, and in particular for internally coating the large end bore of a motor vehicle connecting rod with a bearing coating, wherein the coating material applied to the component surface is converted to a molten state during the coating process. A material bond, which is durable even under high loads, is attained between the coating and the base material of the sintered or forged component without any disturbing residual stresses by a simple manufacturing method due to the fact that during the coating process the component surface is briefly heated in the untreated state of the component above the austenitization temperature to a temperature level having a significantly increased diffusion rate within the limits of the outer edge zone having less carbon for reasons relating to the manufacturing process.
