2. What is Thick Hard Chrome?

Thick hard chrome is a coating obtained through an electrolytic deposition process that allows the application of a metallic chrome layer on a surface. This treatment is performed to ensure a uniform and controlled thickness, with superior mechanical and chemical characteristics.

Key Features:

• High Hardness: The chrome layer achieves a hardness between 800 and 1,000 HV, making it ideal for protecting surfaces subject to wear.
• Corrosion Resistance: Hard chrome offers a protective barrier against aggressive chemical and environmental agents, extending the useful life of components.
• Friction Reduction: The treated surface has a low coefficient of friction, improving mechanical efficiency and reducing energy consumption.
• Thickness Adaptability: The coating thickness can be customized, ranging from a few microns to hundreds of microns, according to specific needs.

Application Process:

• Hard chrome plating is carried out by immersing the component in an electrolytic solution containing chrome, where an electric current is applied to deposit the material on the surface.
• The process is highly controlled to ensure uniformity, adhesion, and coating quality.

Thanks to these characteristics, thick hard chrome represents a reliable and high-performance solution for a wide range of industrial applications.
