Corrosion fatigue of cold spray coated and uncoated Mg alloys
Synopsis: due to the strict environmental laws and energy crisis, lightweighting of transportation vehicles which results into less greenhouses gas emission and better fuel economy, is of major concerns. Steel has superiorities when safety is the target; however aluminum and magnesium have much lower specific strength that can significantly help the gas consumption. The question to be answered is the feasibility of replacing structural parts with lighter metals.
In this project the fatigue corrosion of wrought magnesium alloy will be assessed and compared with steel. The results of this research will help the design of fatigue critical structural members.
Tasks:
- Generating the project plan
- Literature review on Mg corrosion, Mg fatigue, steel corrosion, cold spray coating technology;
- Commissioning of the corrosion chamber;
- Characterization of Mg corrosion with and without coating
- Characterization of fatigue behavior of corroded samples before and after coating
- Comparison of the results with steel
- Consideration of different coating material
Timeline:
It is expected that this work be done in 2 years’ time.
