Evaluation of zinc/aluminum alloy coatings through accelerated and nonaccelerated atmospheric tests

Abstrct:

The Laboratory of Corrosion and Protection of IPT, together with FAPESP – Foundation for Research Support of the State of São Paulo and with CSN – Companhia Siderurgica Nacional, have worked to evaluate the performance of coating zinc alloy / aluminum, compared to the zinc coating in Brazilian atmosphere. The tests were conducted with two types of coating: zinc and Galvalume ®. Through the partnership IPT / FAPESP were developed laboratory tests: characterization of coating and accelerated corrosion tests. By partner IPT / CSN were developed field trials. The coatings were exposed at six different stations atmospheric aggressiveness.
