Role of electroplating:
Protection Against Corrosion
– Shields metal surfaces from rust and chemical damage (e.g., zinc plating on steel).
Increased Wear Resistance
– Hard coatings (e.g., chromium plating) reduce friction and extend part life.
Improved Appearance
– Adds shiny, decorative finishes (e.g., gold plating on jewelry, chrome on car parts).
Better Electrical Conductivity
– Used in electronics (e.g., copper plating on circuit boards).
Enhanced Solderability
– Improves bonding in electronic components (e.g., tin plating).
Repair of Worn Parts
– Restores dimensions and functionality (e.g., rebuilding engine components).
Special Industrial Uses
– Provides heat resistance (e.g., nickel plating in aerospace).
– Used in medical devices (e.g., biocompatible coatings).
Types of electroplating:
› Copper Plating
Purpose: Enhances adhesion for subsequent layers and corrosion resistance.
Note: Prone to oxidation (forms non-conductive copper oxide/green patina). Requires protective coatings.
› Nickel Plating
Purpose: Used as a base layer or decorative finish; improves corrosion/wear resistance. Electroless nickel offers chrome-like durability.
Note: Magnetic properties limit use in electronics (e.g., DIN/N connectors) to avoid signal interference.
› Gold Plating
Purpose: Optimizes conductive contact impedance and signal transmission.
Key: High stability but costly.
› Palladium-Nickel Plating
Purpose: Superior signal transmission and wear resistance vs. gold.
Advantage: Combines palladium’s corrosion resistance with nickel’s hardness.
› Tin-Lead Plating
Purpose: Improves solderability.
Trend: Phased out due to lead concerns; replaced by bright/matte tin alternatives.
› Silver Plating
Purpose: Best conductivity and signal performance.
Note: Conducts even when oxidized but tarnishes over time. Higher cost.
Selection Criteria
Match plating type to application needs: corrosion/wear resistance, conductivity, cost, and environmental regulations.
Elements of Electroplating:
› Cathode
The object to be plated (e.g., connector terminals or metal surfaces) where metal ions deposit into a solid coating.
› Anode
Soluble Anode: Made of the plating metal. Dissolves during electrolysis to replenish metal ions in the solution.
Insoluble Anode: Used for precious metals (e.g., white gold, iridium oxide). Does not dissolve but supplies electrons for reduction.
› Plating Solution
Contains ions of the target metal. Composition and concentration determine coating thickness, adhesion, and appearance.
› Plating Tank
Materials:Polypropylene and titanium alloys excel in harsh conditions with built-in corrosion and thermal stability, making them top picks for chemical-resistant or extreme-temperature applications.
Role: Stores solution and maintains stable plating conditions.
› Rectifier
Converts AC to DC power to drive electrolysis.
Adjust voltage/current to control deposition speed and coating thickness.
› Auxiliary Equipment
Filters: Remove impurities from the solution.
Heaters: Maintain solution temperature.
Stirrers: Ensure uniform mixing.
