    corrosion protection because it renders the metal completely unreactive. It can however be fairly expensive in the consumption of electric power or the extra metals involved in controlling the potential within this region. There are two major methods of applying cathodic protection to a metal structure and these will be discussed below.

    How Metallic Coatings Protect Metals from Corrosion

    Another important aspect of barrier protection is called corrosion film protection. As mentioned previously, some metals, such as aluminum, react with oxygen to form a protective oxide film on its surface. This oxide film is resilient and firmly adheres to the surface of the aluminum to prevent moisture intrusion and further corrosion.

    3 Ways to Prevent Metals from Corroding - wikiHow

    Any method of protection that prevents ion flow between the metals can potentially halt galvanic corrosion. Giving the metals a protective coating can help prevent electrolytes from the environment from creating an electrical conducting path between the two metals, while electrochemical protection processes like galvanization and anodizing also

    Cathodic protection - Wikipedia

    Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode.

    Also consider using cathodic protection to prevent corrosion on the primary metal pieces. Carbon Fiber Coating to Prevent Corrosion in Metal. Carbon fiber coating is another excellent method of preventing the corrosion of metals. In this process, sheets of carbon fiber are sealed around and often inside a metal pipe or on any metal surface.
