发明名称 Method for producing a fracture-divided component, and component produced according to the method
摘要 A method for producing a fracture-divided component, in particular a connecting rod, with an at least partially coated bore includes the steps of: providing an unfinished component; applying a coating of a bearing material to a bore surface; and working the coating, in order to compensate internal tensile stresses in the coating, before fracture division of the component. Alternatively, the method for producing a fracture-divided component, in particular a connecting rod, having an at least partially coated bore includes the steps of: providing an unfinished component; applying a coating of a bearing material to a bore surface before fracture division of the component; and forming a counter-hardness zone before the application of the coating in order to generate compressive stresses which oppose the internal tensile stresses of the coating.

主权项 1. A method of producing a fracture-divided component having an at least partially coated bore, the method comprising the acts of: providing an unfinished component, applying a coating of a bearing material to a bore surface of the component; and working the coating in order to compensate internal tensile stresses in the coating, before a fracture division of the component such that after the fracture division a first fracture portion of the component coated with the bearing material maintains a width dimension equal to a width dimension of a second fracture portion of the component.
