Improved corrosion inhibiting structure

改进的防腐蚀结构

Abstract

The present invention relates to a vehicle comprising a metal structure assembly with an improved corrosion resistance. The metal assembly comprises a first and a second metal member (11, 12), the first metal member (11) comprises a steel sheet having a first surface (20), and the first surface (20) is coated with at least one alloy. The second metal member (12) is an alumina member having a first surface (23). Furthermore is the first surface (20) of the first metal member (11) is attached to the first surface (23) of the second metal member (12) at at least a first attachment area (30). The at least one alloy comprises Mg. The metal assembly according to the present invention is proved to be very corrosion resistant but also very resistant towards local corrosion attacks in the form of pits.
本发明公开了一种改进的防腐蚀结构,具体涉及一种包含具有改进的耐腐蚀性的金属结构总成的车辆。该金属总成包含第一金属构件和第二金属构件(11,12),第一金属构件(11)包含具有第一表面(20)的钢板,第一表面(20)涂覆有至少一种合金。第二金属构件(12)为具有第一表面(23)的铝构件。此外,第一金属构件(11)的第一表面(20)至少在第一连接区域(30)处连接至第二金属构件(12)的第一表面(23)。该至少一种合金包含Mg。根据本发明的金属总成证明有很高的耐腐蚀性,而对凹陷形式的局部腐蚀侵蚀也很有抵抗性。
