Description
The behavior of carbon steel 20 corroded by chemical cleaning action of a 10% solution of ortho phosphoric acid with a view to a subsequent application of different methods of conservation, are presented in this work. The phase composition of samples with corrosion products coats as well as the clean surfaces are study by electron conversion. Moessbauer spectroscopy (ECMC) which allow to analyze surface fine coats (300 nm) adhered to the substratum. The corrosion resistance of the surface after the treatment was determined by the galvanostatic technique comparing the results with samples mechanically plane down. For the evaluation of weight loss, gravimetric tests were carry out and condition of the surfaces were observed with the optical microscope. (Author)
