摘要:
The invention relates to a method for coating a surface of an Fe based, hardenable sintered, sinter forged, or forged component, particularly 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 melted liquid state during the coating process, wherein according to the invention a material bond that is durable even under high loads is achieved between the coating and the base material of the sintered or forged component in a simple manufacturing method, in that the component surface is briefly heated during the coating process in the unprocessed state of the component, above the austenitization temperature to a temperature level having greatly increased diffusion speed, within the limits of the exterior boundary zone having less carbon due to manufacturing conditions.
摘要(中):
本发明涉及一种用于涂覆Fe基可硬化烧结,烧结锻造或锻造部件的表面的方法,特别是用于在内部涂覆机动车辆连杆的大端孔与轴承涂层,其中涂覆到 在涂覆过程中将部件表面转化为熔融液态,其中根据本发明,通过简单的制造方法在涂层和烧结或锻造部件的基体材料之间实现即使在高负载下也耐用的材料结合 这是因为在部件的未加工状态的涂覆过程期间,在奥氏体化温度以上的扩散速度大大增加的温度水平下,部件表面在由于制造条件而具有较少碳的外部边界区的范围内被短暂地加热 。
