Way back in 1824, a certain Sir Humphrey Davy in the UK, noticed that the copper sheeting on warships was decaying rapidly, and made it his business to try to do something to prevent this from happening, to lengthen the life of His Majesty’s ships of war. He realized that it was due to the constant contact with seawater, which was causing the copper to corrode and, while conducting an experimental investigation, discovered that iron anodes helped tremendously, to protect the copper, and cathodic protection was born.
However, one of the side effects of this process was increased marine growth on the ships, which had an adverse affect on their performance. After some deliberation, the Royal Navy decided that it was better to allow the copper to corrode as it normally did, than have to deal with the extra marine growth on their ships, so Davy’s discovery was not used any further. Davy carried on with his experiment, assisted by a pupil of his, Michael Faraday, who continued with these experiments after Davy’s death. Faraday discovered a connection between corrosion and electric current in 1834, which actually formed the basis of cathodic protection as we know it today.
Even Thomas Edison experimented on ships in 1890, but, because of the lack anode material and suitable current source, was not successful. It was only in 1928 that the United States started making use of cathodic protection on oil pipelines – more than one hundred years after Davy’s experiments.
Cathodic protection basically, is the technique of making a metal surface the cathode of an electrochemical cell, in order to protect that metal surface from corrosion. The simplest way to apply it, is to connect the metal that needs protecting, to another metal that is more easily corroded, a sacrificial metal in other words, making it perform as the anode of an electrochemical cell.
Sacrificial anodes are manufactured in various sizes and shapes, using alloys of zinc, aluminum and magnesium. Zinc anodes have high driving voltage, and are suitable protection for marine structures and pipelines against corrosion caused by seawater. Zinc alloy anodes can also be used in areas where sparking is a risk and needs to be avoided, such as in tanks where flammable hazards are stored.
Cathodic protection is commonly used in steel fuel or water pipelines, storage tanks, steel piers and jetties, offshore oil platforms, onshore oil well casings, as well as the metal reinforcement bars which are used the majority of the time, in concrete structures and buildings. Cathodic protection also used in some cases, to prevent stress corrosion cracking as well.
Zimar Zincs are basically the industry standard when it comes to Zinc Anodes. Ask most expert boaters who they use for Zinc Anodes, and they will respond with a resounding answer of Zimar Zinc Anodes. Deep Blue Yacht Supply carries the complete line of Zimar Zinc anodes, order yours today and save.
If you use your yacht primarily in saltwater, a high quality zinc anode is the best way to protect against corrosion. Premium quality zinc can be difficult to come by, however, as many manufacturers introduce impurities to their zinc as part of the die casting process that render it less effective. Zimar International takes great pride in hand-pouring every zinc anode mold, ensuring a premium product every time.
Zimar uses only special zinc ingots containing 99.995 percent pure zinc, so you're not paying for any cheap filler materials that fail to directly help your boat. This purity is preserved by the hand pouring process because it avoids the molecular structure changes that can result from die casting. As a result, Zimar zinc anodes offer a shinier exterior and interior than their competitors, giving you a strong visual indication of their superior quality and performance.
Zimar traces its history back to 1982, when Venezuelan native Jose Alegre discovered that he was having a hard time equipping his personal boat with quality zinc anodes. He launched a company to fill this need in the marketplace, ultimately moving to Fort Lauderdale, Florida to take advantage of the city's reputation as the Yachting Capital of the World.
Today, Zimar continues to manufacture all of its products in the United States. Alegre has transferred control of the business to his two sons, JC and Jose Jr, maintaining its status as a family-run business dedicated to meeting and exceeding the needs of consumers.
As yachting continues to grow in worldwide popularity, Zimar has expanded its product offerings to include over 250 zinc anodes. A diverse array of anode types are available, such as shaft anodes, round anodes, plate anodes, wire anodes, and weld-on anodes. All of the most popular yachting brands are also represented, including Viking, Ocean Alexander, Marlow Explorer, Palmer Johnson, and Sea Ray. A complete catalog of the company's products is available online at ZimarInternational.com by clicking on the Catalog tab toward the bottom of the homepage.
Aluminum anodes have become increasingly popular in the boating industry over recent years due to their lighter weight and increased electrical conductivity, but they run into several problems in saltwater. The metal corrodes, creating film layers and white soft spots that prevent the anode from performing as intended. Pure zinc does not have any of these issues in saltwater, making it the premier choice for saltwater crafts.
The fact that zinc is heavier than aluminum also makes it more durable, requiring less frequent replacement on your part. If you hate swapping out anodes on your yacht, Zimar zinc anodes minimize how often you need to do so.
Whether you own a yacht, manage a boat yard, or enjoy deep sea diving, you owe it to your yourself to try Zimar's line of premium zinc anodes. They offer the superior quality and performance that every boat enthusiast craves.
