What process is used in electroplating?

Electroplating is essentially the process of depositing a metal or alloy coating on the surface of a workpiece through electrolysis. Based on the application and coating characteristics, it is mainly divided into the following categories:

1. Decorative Electroplating: Primarily for aesthetic and protective purposes, commonly used in hardware, sanitary ware, and automotive parts.

• Chromium plating: Provides a bright, high-hardness surface.
• Nickel plating: Excellent corrosion resistance and gloss.
• Zinc plating + passivation: An economical and effective steel protection solution.

2. Functional Electroplating: Focuses on imparting special properties to the workpiece, widely used in high-end manufacturing such as electronics and aerospace.

• Hard chrome plating: Extremely high wear resistance, used for repairing mechanical parts.
• Chemical nickel plating: No external power supply required, produces a uniform and dense coating.
• Precious metal plating (gold, silver, palladium): Used in electronic connectors to ensure conductivity and reliability.

3. Specialty Electroplating Processes: Cutting-edge technologies developed for specific needs.

• Pulse electroplating: Improves the crystal structure of the plating layer through intermittent current.
• Alloy electroplating: Deposits two or more metals in a single pass.
• Composite electroplating: Embeds microparticles into the plating layer to achieve special properties.

• Regardless of the electroplating process used, a high-performance electroplating rectifier is a crucial piece of equipment determining success or failure. It converts alternating current (AC) into stable direct current (DC), directly affecting:
• Current stability: Current fluctuations of less than 1% ensure uniform plating;
• Plating quality: Precise voltage control avoids defects such as scorching and blistering;
• Energy efficiency: High-efficiency rectifiers can reduce energy consumption by 15-30%;
• Process adaptability: Different processes have different requirements for waveforms (DC, pulse, periodic reverse).
