For many years, thermally sprayed metal coatings have been widely accepted for giving very long protection lifetimes. Experience in Norway (on bridges, for example) and numerous tests in Europe and the US,1 show that the lifetime, orthe time to the first necessary maintenance work, of thermally sprayed aluminum (TSA), combined with a paint coating system, can be more than 50 years.  \nDevelopment of the Norwegian oil fields in the North Sea started with the Phillips Ekofisk Field in 1972, and it has progressed rapidly since then. TSA was almost not in use at all in the offshore industry until 1984-85.2 During construction, it was used only in a few special areas that would have very difficult or impossible access for maintenance during the operation of the platform (e.g., the flare boom). However, the increased application costs for TSA could be justified by the expected decrease in the cost of future maintenance. (For a comparison of the costs of TSA coatings and conventional systems, see \"Offshore Protection: Painting for a 20-Year Life\" in the April 1996 issue of PCE.3)  \nSeveral platforms built during the last six years, and most of those now underconstruction, have TSA as one of the corrosion protection coating systems. The real breakthrough came with the development of the Shell Draugen Field in 1991 where the whole underside of the platform, the lifeboat stations, and the flare boom were coated with TSA. The Sleipner Riser Platform (Statoil) and the Troll Gas development (Shell) also are using TSA as the main corrosion protection system.  \nThe Basics  \nTSA Application Methods  \nThe term \"thermally sprayed aluminum\" (TSA) covers several application methods. Electric arc spraying and flame spraying are the most suitable methods for the corrosion protection of steel structures.  \nElectric arc spraying is performed by feeding two electrically conducting aluminum metal wires towards each other. An electric arc is produced at the point just before the wires meet. The arc melts the metal wires, and a highpressure air line is used to spray the fine droplets onto the steel surface, which has been previously cleaned and prepared.  \nIn flame spraying, a metal wire is melted in a gas flame and then air-sprayed onto the steel surface.  \nElectric arc spraying is by far the more commonly used method in the Norwegian offshore industry, and the terms TSA coatings and metalizing in this article refer to electric arc thermally sprayed aluminum.  \nSurface Preparation  \nBefore coating, the steel surface is blast-cleaned to Sa 3 according to ISO 8501, Preparation of Steel Substrates Before Application of Paints and Related Products-Visual Assessment of Surface Cleanliness.  \nCoating Systems  \nThe prepared surface is coated with 200-400 microns AlMg5 (aluminummagnesium alloy), which then usually is painted with an organic coating, such as epoxy, urethane or acrylic.  \nThe choice of organic coating depends on the temperature to which the surface is exposed. For low temperature use, a sealer is applied to the TSA surface to seal the pores of the metal coating. This usually is followed by two coats of paint. For high temperature use, a heat-resistant sealer coat only is applied. The requirement for adhesion varies, but the latest specifications usually state a minimum requirement of 7 MPa and an average of 12 or 14 MPa.  \nWhy Use TSA Coatings?  \nTSA coatings find use in a variety of environments, including the following:  \nAtmospheric areas-The main reason for using TSA coatings in areas subject to atmospheric exposure is to reduce the need for future maintenance. Maintenance costs for existing constructions have been increasing rapidly due to the fact that m","cbCairZaOZUg25MV","https://ap.wps.com/l/cbCairZaOZUg25MV","pdf",86303,"English","# The Basics\n## TSA Application Methods\n## Surface Preparation\n## Coating Systems\n## Why Use TSA Coatings?\n## Atmospheric areas\n## Submerged areas\n## Special areas (pipe work and tanks)","[{\"question\":\"TSA为什么能在挪威海上结构中提供较长的防腐寿命？\",\"answer\":\"文中指出，热喷涂铝（TSA）与涂装体系配合可使维护周期显著延长，经验和多项欧洲及美国测试显示可超过50年，延后首次必要维护。\"},{\"question\":\"TSA的主要施工方法有哪些，挪威海上行业通常采用哪一种？\",\"answer\":\"TSA覆盖电弧喷涂与火焰喷涂等方式，用于钢结构腐蚀防护最合适。文中强调挪威海上行业中电弧喷涂应用更普遍，文内的TSA涂层多指电弧热喷涂铝。\"},{\"question\":\"涂覆前的钢材表面处理标准是什么？\",\"answer\":\"在涂覆前，钢材表面需按ISO 8501进行喷射清理至Sa 3，以满足《涂料及相关产品应用前钢基材的表观清洁度评估》的要求。\"},{\"question\":\"TSA涂层在大气、浸没与特殊区域分别解决了什么问题？\",\"answer\":\"大气区域的重点是减少未来维护需求；浸没区域可降低对牺牲阳极的需求（相比裸钢电流需求更低）；特殊区域（如管道与储罐）则可降低在超级双相不锈钢中发生氯离子应力腐蚀开裂的可能性。\"}]","Thermally Sprayed Aluminum in the Norwegian Offshore Industry - Volume 2 - Number 4 | PDF",25]
