Quality Evaluation of Corrosion Loaded Sheets Metal Using the Microstructural Analysis

Abstract

At present is the global trend dealing with environmental protection. This trend is mainly affected industries, which includes field of surface treatment. Study of surface treatment (surface pre-treatment and coatings) has great impact on the working and living environment. In this context it is necessary to solve the issue of hazardous organic volatile compounds, wastewater discharge, etc. The paper deals with quality evaluation of corrosion loaded sheets metal using the microstructural analysis. These steel plates were pre-treated in three different ways, when it was used a new method of surface preparation based on the nanotechnology and classic technology of ferric phosphate. The test specimens were subjected to the corrosion test chamber and after removal from the corrosive environment was performed microstructural analysis. Experimental samples were compared in terms of quality and corrosion resistance surface protection.
