Corrosion of High-temperature Alloy Parts in Brush Plating

The corrosion reasons of high-temperature alloy parts in brush plating were analyzed.The corrosion conditions were simulated by technical experiments.Results showed that the electric conductivity between alloy parts and tongs was the primary corrosion reason.The plating solution in the crevice could bring different types of corrosion.Under good conductivity condition,obvious crevice corrosion would not appear in brush plating.
