In this study, a green chemical milling, Green Etching (Patent pending), is applied to B356.2 Aluminum alloy with the aim to remove a controlled thickness layer from the surface with no buckling and maintaining excellent dimensional toler- ances. Comparison of the fatigue life of un-treated and chemically treated samples is performed, with the aim to determine how the above mentioned chemical treatment influences the fatigue resistance of the Al alloy to be used in automotive/aircraft industrial application. The results revealed that the fatigue properties of Al casting alloy are influenced by the presence of casting defects and the fatigue resistance can not be significantly compromised by the milling treatment despite the surface roughness induced by the treatment.

Abstract
In this study, a green chemical milling, Green Etching (Patent pending), is applied to B356.2 Aluminum alloy with the aim to remove a controlled thickness layer from the surface with no buckling and maintaining excellent dimensional toler- ances. Comparison of the fatigue life of un-treated and chemically treated samples is performed, with the aim to determine how the above mentioned chemical treatment influences the fatigue resistance of the Al alloy to be used in automotive/aircraft industrial application. The results revealed that the fatigue properties of Al casting alloy are influenced by the presence of casting defects and the fatigue resistance can not be significantly compromised by the milling treatment despite the surface roughness induced by the treatment.Pubblicazioni consigliate
