An assembly for a vehicle having reduced galvanic corrosion includes a first component defining at least one interface region that includes a carbon-fiber reinforced polymeric composite (CFRP) and a first material present in the at least one interface region and having a first electrochemical potential. A second component has a second material and is in contact with the at least one interface region of the first component. The second material has a second electrochemical potential different than the first electrochemical potential. In this manner, in the presence of an electrolyte the first material may be either less noble than the second material and serve as a sacrificial material or alternatively more noble to the second material reducing a driving force for corrosion. Methods of reducing galvanic corrosion in an assembly (e.g., for a vehicle) are also provided.
一种具有减少的电腐蚀的用于车辆的组件包括限定至少一个界面区域的第一部件,该第一部件包括碳纤维增强聚合物复合材料(CFRP)和存在于至少一个界面区域中并具有第一电化学势的第一材料。第二部件具有第二材料并且与第一部件的至少一个界面区域接触。第二材料具有不同于第一电化学势的第二电化学势。以这种方式,在存在电解质的情况下,第一材料可比第二材料更不惰性并用作牺牲材料,或者另选地比第二材料更惰性,从而降低腐蚀的驱动力。还提供了减少组件(例如,用于车辆)中的电腐蚀的方法。
