zinc-plating

When zinc-plated parts show white powdery rust within days, the passivation has failed. Learn the root causes, from bath contamination to curing errors.

Steel is the most common substrate for electroplating, but it is highly vulnerable to corrosion. Explore the engineering choices between Zinc, Zinc-Nickel, Nickel, and Copper when plating on carbon and mild steel.

A comprehensive guide to modern RoHS-compliant trivalent passivations for zinc plating. Understand the differences in corrosion resistance, color stability, and performance among clear, yellow, and black conversion coatings.

A technical guide to acid chloride zinc plating. Understand its superior brightness, high plating speed, and direct plating capabilities onto cast iron, contrasted with its throwing power limitations.

Understand the chemistry behind white rust (zinc hydroxide) formation on zinc-plated parts. Learn how proper passivation, sealing, and storage environments can prevent this common but destructive storage defect.

Comparing standard zinc electroplating with zinc-nickel alloy plating. Understand the differences in corrosion resistance, cost, temperature stability, and when an upgrade to zinc-nickel is justified.

A detailed breakdown of ASTM B633, the standard specification for electrodeposited zinc coatings on iron and steel. Learn how to decipher thickness classes, types, and post-plating requirements.
