Latest Patents
David R Arnott holds a patent for a "Method of determining susceptibility of alloys to stress corrosion - Accelerated testing method for determining the susceptibility of alloys to stress corrosion cracking." This method involves anodizing test parts to create an oxide coating, which is then deformed to induce tensile strain. The microcracks that form in the oxide coating serve as indicators of where stress corrosion cracks may develop during service. The process includes reanodizing the parts to heal the microcracks and recording the transient current during reanodization. The rate of current decay is indicative of the alloy's susceptibility to stress corrosion cracking. This patent highlights Arnott's innovative approach to enhancing the reliability of alloy materials.
