Effects of coating porosity, thickness and residual stress on stress and fatigue behavior of micro-arc oxidation coated aero Al alloys
The stress analysis of micro-arc oxidation (MAO) coated aero Al alloys is the basis to reveal the mechanism of fatigue deterioration.To clarify effects of the coating 27" True Convection Wall Oven defects on fatigue life, a stress calculation model with micropores and residual stress is established based on shear lag model in this study.The effects
