Conversion layers substituted to hexavalent chrome in the anti-corrosion protection of galvanized steel
Metals/metal alloys are among the most used materials in the industrial environment. Among these, ferrous alloys have been widely applied in different segments of the industry such as: automotive, chemical, oil and gas, etc. Due to the different environmental conditions in which this material is applied, there are situations that can cause steel degradation, in a phenomenon known as corrosion. The degradation of the metal by the effect of corrosion generates environmental and economic impacts, which cause a decrease in the cost-benefit ratio.
