    摘要： A method of mitigating galvanic corrosion on a vehicle is provided for use of metals with carbon containing composites. An electrically conductive material comprising a plurality of electrically conductive metallic particles and a polymer is applied to a corrosion susceptible region of an assembly having a carbon-reinforced composite and a metal. The electrically conductive material has an electrical conductivity of greater than or equal to about 1×10−4 S/m and serves as a sacrificial anode to mitigate or prevent corrosion of the metal in the assembly. Also provided are assemblies for a vehicle having reduced galvanic corrosion that include a metal component in contact with a carbon-reinforced composite, which defines a corrosion susceptible region having an electrically conductive material disposed therein.

    摘要： A method to produce an electrode by coating at least a portion of a valve metal substrate sequentially with first and second liquid solutions containing different proportions of dissolved ruthenium and valve metal values; the second solution having a greater valve metal to ruthenium weight ratio than the first solution. At least a portion of the substrate is contacted with a first liquid solution containing ruthenium and the valve metal in amounts of from about 1 to about 50 milligrams per milliliter of the solution. The weight ratio of the valve metal to ruthenium in the first solution is from about 1:4 to about 2:1. The so-contacted surface is heated to oxidize the deposited ruthenium and valve metal values. Thereafter at least the oxidized surface is contacted with a second solution containing dissolved valve metal and ruthenium values in a weight ratio of from about 20:1 to about 2:1 and heated to oxidize the deposited metal values.

    摘要： An anode assembly and method for installing it in a cathodic protection system for an aboveground storage tank is disclosed. The anode assembly basically comprises an elongated electrically conductive anode, a fabric housing and sand backfill. The fabric housing is a hollow member in which the sand is located and through which the anode extends. The anode includes portions extending out of the housing for connection to the cathodic protection system. The anode assembly is arranged to be installed on a flat prepared surface below the bottom of the storage tank, whereupon the anode assembly's weight hold it flat on that surface without the need for staking or other means to hold the assembly flat. The ground with the anode assembly can then be backfilled to the level of the bottom of the storage tank.

    摘要： Impressed current anodes such as cathodic protection anodes comprise iron based alloys including less than 70% iron and less than 0.1% carbon. Additional components may include molybdenum, chromium, nickel and others. The iron based alloy may itself comprises the anode or it may provide a substrate to which an electrolytic coating is applied.
