But the important part is it happens slowly and over many years, allowing the owner to blame time and not lack of work for the deterioration of the boat. During a maintenance check in the 1980s, workers discovered that the Statue of Liberty had a serious structural issue: the statue's internal wrought iron support system was rusting over because the insulating layer of shellac between the iron and copper had failed and allowed for galvanic corrosion to occur. Instead of rusting, brass may develop a patina, a greenish layer of tarnish due to oxidation, after years of exposure to oxygen and other elements. Stainless steel is typically compatible with bronze but there are a few considerations to keep in mind. The difference only emerges when the two materials are pushed to their breaking point. However, by taking a few measures, its possible to ensure that your buildings stay safe from galvanic corrosion. Yes, silicon bronze would probably be OK, but Al bronze is stronger and has quite a bit more corrosion resistance. Since everyone wants stainless steel for every part of their yacht, stainless steel is all you will find for sale everywhere you look. The concern is where there can be a current passing through or between them if they're in salt water.then galvanic action will corrode the more susceptible of the two metals. As you're aware, it's the presence of an ultra thin oxide layer (mostly Cr oxide) that gives SS its corr. Under normal loads, both materials operate on your yacht in an identical fashion. But there is one problem with removing all the brightwork; people like shiny things! The reason why stainless steel is very popular is because it is resistant to corrosion, heat, and abrasion, making it a safe and reliable material for use in a wide range of industries. Brass can be protected from corrosion by sealing the surface, or by periodically cleaning it to remove any material that might cause corrosion.
