Aleaciones especiales aplicables a las condiciones ambientales en la zona del puerto de Guayaquil

Abstract

There have been accelerated corrosion tests in salt spray chamber in order to know how aggressively they possess the polluted salt marsh in the seaport area and especially in the southern base of the Ecuadorian Navy on metal materials, where it is known that there are large environmental corrosion problems not only their marine condition, but also because it was verified that the pH of the water of the estuary is less than 7 and has been modified by industrial pollution which leads to failure of materials resistant to marine environments. The objective of this thesis was a study of the corrosion of engineering materials known to determine the rate of deterioration of them. The metals selected for evaluation in a standard salt spray chamber using the ASTM B117 specification are: Aluminum bronze, Stainless Steel AISI 304 Stainless Steel AISI 306 Stainless Steel 406, Brass and Brass or bronze called Silver Cupro - Nickel (Cu 30% Ni).
