Process for depositing an organic acid on the surface of a metal composition

A process for modifying a surface of a metal comprising:

• providing a metal surface having a metal oxide, wherein said metal is nitinol,
• contacting said metal oxide with an organic acid solution or aerosol having a combination of a concentration of from 0.35 mM to 2.0 mM and a temperature ranging from above 0° Centigrade to 120° Centigrade and having a hydroxamic acid or a carboxylic acid functional group, wherein said carboxylic acid has a formula CO2HCnH2nX or wherein said hydroxamic acid has a formula XCONHOH, and wherein X is selected from the group consisting of CH3, COOH, OH, NH2, and Br, and n is a number ranging from greater than about 4 to less than or equal to 30, and
• depositing said organic acid having said functional group on the surface of said metal oxide by solution or spray deposition for providing a modified metal surface wherein said organic acid that is deposited on said surface of said metal oxide has a monolayer free of micelle or island formation and a thickness ranging from greater than or equal to 12 Angstroms to less than or equal to 100 Angstroms.
