Core Advantages of Chrome Plating
Chrome coating brings multiple upgraded performance for finished components:
- Ultra-High Hardness & Outstanding Wear Resistance: Extend service lifespan of high-friction moving parts such as hydraulic rods and forming molds.
- Powerful Anti-Corrosion Performance: Form dense barrier coating to block moisture and chemical erosion in severe working environments.
- Low Surface Friction: Reduce operational abrasion of sealing assemblies and cut equipment leakage rate effectively.
- High-Gloss Decorative Finish: Mirror bright surface for automotive trim and precision hardware appearance demands.
- Dimensional Restoration: Reclaim dimension of worn spare parts back to original specification via controlled chrome buildup.
Standard Chrome Plating Process & Specs
Precision Pre-Treatment
- Conduct degreasing, pickling and surface activation to remove oil, rust and oxides
- Control surface roughness Rz 2–3 μm for strong coating adhesion
- Apply specialized zincating treatment for aluminum substrates
Nickel Underlayer Plating
- Deposit uniform nickel layer to enhance bonding strength and corrosion resistance
Chrome Plating Parameter Control
- Stabilize bath formula, temperature (50–60℃) and current density
- Ensure even coating on complex-shaped parts
Hydrogen Embrittlement Relief
- Bake high-strength steel (＞40HRC) post-plating to eliminate hydrogen and prevent cracking
Final Quality Inspection
- Test coating adhesion, hardness, thickness, wear resistance and appearance before delivery
Available Base Substrates & Plating Raw Materials
Applicable Base Materials
Alloy steel, stainless steel, copper, brass and aluminum alloy; customized pre-treatment available for special engineering substrates.
Plating Bath Raw Materials

Two Main Chrome Plating Types For Industrial Customization
- Hard Industrial Chrome Plating: Functional thick coating focused on wear resistance and low friction; widely applied on hydraulic cylinder rods, transmission shafts and injection molding dies.
- Decorative Chrome Plating: Multi-layer Cu-Ni-Cr composite coating featuring mirror glossy finish, used for automotive exterior trim, hardware fittings and medical instrument appearance parts.
Major Industrial Application Distribution
- Automotive & Transportation: Shock absorber rods, piston rings, brake pistons and decorative exhaust tips (accounts for 43% of total plating demand).
- Aerospace & Defense: Landing gear fittings, hydraulic actuators and turbine blade wear surfaces against extreme heat and pressure corrosion.
- Hydraulic & Heavy Machinery: Chrome plated cylinder rods and roller shafts to minimize seal abrasion and prevent system leakage.
- Medical Devices: Biocompatible chrome coated surgical cutters and orthopedic auxiliary parts easy for regular high-temperature sterilization.
- Mold & Tooling: Anti-stick chrome surface for plastic & rubber forming molds to boost continuous production efficiency.
