Abstract
A corrosion inhibiting composition including a liquid carrier having a surface tension of at most about 35 dynes/cm and an electrically conductive nanomaterial dispersed in the carrier.
Claims20
A method for inhibiting corrosion of an electroplated structure comprising:
- applying to said electroplated structure a composition comprising:
- a liquid carrier having a surface tension of at most about 35 dynes/cm;
- and
- an electrically conductive nanomaterial dispersed in said liquid carrier, wherein a weight ratio of said liquid carrier to said electrically conductive nanomaterial ranges from about 120:1 to about 30:1,
- wherein said electroplated structure comprises a metallic substrate and electroplating directly on said metallic substrate, said electroplating defining an external surface and said electroplating comprising microcracks, and wherein said applying occurs for a duration of time such that at least a portion of said electrically conductive nanomaterial is received in said microcracks;
- and
- removing said composition from said external surface of said electroplating while leaving said electrically conductive nanomaterial within said microcracks.
