钢上热喷涂铝是一项业已证明在海洋环境中可行的技术。这种热喷涂涂层体系在给涂层上涂有封孔漆，这将会延长涂层的使用寿命，并给产品提供颜色。这种热喷涂体系通过隔离和电化学两种原理对钢提供保护。由于这种双重保护，使得甚至在涂层损坏后还可以对钢提供防腐。但直到前不久，由于初次涂覆的费用而使其广泛的应用受到限制。电弧喷涂技术已经将热喷涂铝涂层的费用降低到低于涂漆。工业造船商可以利用该技术提高其在海洋工业中的地位。
Thermal sprayed aluminum on steel is a proven technology that is viable in the marine environment. This thermal spray coating system is applied with a sealer on the coating, which will extend the useful life of the coating and provide the product with a color. This thermal spray system protects the steel by both galvanic isolation and electrochemistry. Thanks to this double protection, the steel can be preserved even after the coating is damaged. However, until recently, its widespread application was limited by the cost of primary coating. Arc spraying technology has reduced the cost of thermally sprayed aluminum coatings below paint. Industrial shipbuilders can use this technology to enhance their position in the marine industry.
