Abstract
Articles including a conductive metal substrate and a protective coating on the metal substrate are provided. The protective coating is electrochemically deposited from an electrodeposition medium including a silicon alkoxide and quaternary ammonium compounds or quaternary phosphonium compounds. Methods of electrochemically depositing such protective coatings are also described herein.
Claims13
An article comprising:
- an electrically conductive metal substrate and a protective coating, the protective coating electrochemically deposited from an electrodeposition medium comprising:
- a silicon alkoxide;
- one or more quaternary ammonium compounds or quaternary phosphonium compounds, wherein the one or more quaternary ammonium compounds or quaternary phosphonium compounds are selected from the group consisting of tetra butyl ammonium hydroxide, benzyl triethyl ammonium hydroxide, tetra ethyl ammonium hydroxide, tetra methyl ammonium hydroxide, benzyl trimethyl ammonium hydroxide, trimethyl hydroxyethyl ammonium hydroxide, tetra butyl phosphonium hydroxide, benzyl triethyl phosphonium hydroxide, tetra ethyl phosphonium hydroxide, tetra methyl phosphonium hydroxide, benzyl trimethyl phosphonium hydroxide, and trimethyl hydroxyethyl phosphonium hydroxide;
- and
- water;
- wherein the article is at least one of one or more electrically conductive wires in an overhead conductor.
