Zinc-dipped components are widely used in structural parts, spring washers, fasteners, castings, and forgings in subways, tunnels, petrochemical and marine engineering, power and communication facilities, and other fields requiring high corrosion resistance, high wear resistance, no hydrogen embrittlement, and environmental friendliness.
Zinc-dipped components feature high bonding strength, high hardness, no hydrogen embrittlement, uniform thickness, and environmental friendliness (no pickling wastewater). Compared with electroplating, hot-dip galvanizing, and Dacromet processes, zinc-dipped layers are thicker (20~30µm) with controllable thickness, uniform depth, good continuity, diffusion metallurgical bonding, and high bonding strength; they also offer higher hardness (Hv220~450).
