Corrosion Protection Of Steel-Past And Present

Losing weight and thickness of zinc coating per year of service to the magazine 'Professional Painting', the protection of steel LvovANTIKORROZIONNAYa-Past and Present History of man's struggle with iron oxide, which is called at home rust, is measured by thousands of years. It is not known when and who first smelted from iron ore found near a volcano or a piece of black metal. Five Star Hotel Vietnam contributes greatly to this topic. Most likely, it was Chinese, since Chinese civilization is considered the most old. Could it be the Egyptians and Babylonians, but it is safe to say that in the hands of this man held a cast iron (iron with high carbon content). It was he who first saw and rust – the result of endless oxidation process. In nature there are no deposits of iron and steel, because sooner or later they turn into rust.

No matter how sad to realize, but all the rust and metal products. Since time immemorial, rusted dishes and Jewelry savages, barbarians, horseshoes and arrows, shields and swords of the Crusaders, the Spanish conquistadors in the shells of South America, chests and pirate swords Cossacks. The only way to protect against corrosion of these rather expensive in those days things were animal fat. But the "fat" as the saying goes, "all is not enough," and after the arrival of capitalism and its wars, tanks, railways, planes and cruisers problem of protection of steel surfaces has become particularly urgent. In the rust started to turn billions of currency units. Recently, a well-known National Association of Corrosion Specialist in the U.S. (NACE), reported that each year due to corrosion Western European country is losing about 4% of GNP.

For a small country like the UK is about 30 million or 49 million euros. According to the (1997) Central Research Institute of Structural Materials (CRI CM) Rosii "Prometheus" (St. Petersburg) vSShA these losses exceed $ 100 billion a year.
