The aim of this research is, to investigate the influence of two types of cyclic salt spray tests on parts surface treated with galvanizing.
On the selected components was performed the method Zn-Ni surface treating on the bath line. Subsequently were the components embedded in the corrosion chamber, where was performed two types of cyclic salt test. In the first test was performed 4 hour salt spray, 8 hours drying, 60 hours condensation and 24 hours drying. Once cycle lasted 96 hours, and it was repeated 4 times. During the second test was performed 2 hours salt spray, 2 hours condensation. The cycle was repeated 4 times, that means 96 hours. After the cycle was performed 72 hours free relaxation in the corrosion chamber, on 20-25 °C temperature.
As the research showed, after the cyclic salt spray was no red corrosion on the selected components. The white corrosion appeared only slightly.
