In daily life, metals are used in everywhere and they are the main parts of technical and mechanical devices. They should be strength enough to endure the conditions in the environment such as pressure, forces, temperature and the hardest one corrosion. Metals have some processes to increase their endurance through such difficulties. One of the easiest ways to increase the metal’s endurance is coating. This method is used in almost all areas such as engineering, ships and electrical devices and even in mechanic industry for protection and endurance. One of the most important areas of metal coating is to inhibit corrosion in metal surface. Metals react with oxygen in daily life. To prevent these oxidation reactions metal coating is used. Zinc, chrome, platinium, etc. Are commonly used in coating metals due to their low oxidation potential they have. In this study, the research was chosen to be “Would endurance for corrosion of different coated metals in salt solution be different?” Zinc, chrome, iron, copper and nickel coated metals, made by same factory and by the same process, was used in the study. Salt solutions prepared and coated metals were sink into these solutions to observe the corrosion or changes. Some changes such as colour change on the metal surfaces and salt solutions were observed at the end of the experiment. All changes were noted in 5 day interval and after a 30 day period, the metals were compared with each other respect to these changes. It is realised that the best metal which has best endurance to corrosion is chrome. Because, after the 30 day period there is no evidence which shows chrome corrodes. The endurance of metals to corrosion goes from most endurance to less one as copper, nickel, iron, zinc.
