Electroplating Chromium
Protection for durable metal surfaces
LMV BLOG – Lauingen July 8, 2025
Chromium electroplating is a crucial process for making metal surfaces durable, corrosion-resistant, and visually appealing. For companies that value the quality and preservation of their metal components, chromium electroplating offers an efficient solution to protect surfaces against wear and achieve a high-gloss finish.
1. Key Facts at a Glance
- Chromium electroplating effectively protects metal surfaces from corrosion and wear.
- The method improves the appearance by providing a uniform, mirrored, or matte surface.
- Even complex parts can be precisely chromium-plated.
- The process significantly extends the lifespan of components.
- Ideal for Hospitality, Mechanical Engineering, Hardware Technology, and Medical Technology
2. What is Chromium Electroplating and Why is it Relevant?
Chromium electroplating is an electrochemical process in which a chromium layer is applied to metal parts to protect them from external influences and to refine their surface. The chromium layer increases scratch resistance, reduces friction, and gives the workpiece a high-quality appearance. For companies that want to ensure high quality for their products, chromium electroplating is a sustainable investment in the longevity and appearance of components.
3. Process and Technical Details
The chromium electroplating process can be divided into clear steps:
Step 1. Cleaning and Degreasing:
The workpiece is thoroughly cleaned, degreased, and freed from oxide layers to ensure optimal adhesion of the chromium layer.
Step 2. Nickel Plating:
- Nickel electroplating is an electrochemical process in which a thin layer of nickel is applied to a workpiece to achieve corrosion protection and an improved appearance.
- Electroplated nickel surfaces can be matte, semi-gloss, or high-gloss, depending on the additives used in the electrolyte.
Step 3. Chromium Electroplating:
- Trivalent chromium electroplating is a surface finishing process in which a thin, glossy chromium layer is applied to a workpiece, using trivalent chromium (chromium III) instead of hexavalent chromium (chromium VI).
- This process is a more environmentally friendly alternative to traditional hexavalent chromium plating, as it is less toxic and better meets the requirements of the EU chemical regulation REACH.
Step 4. Rinsing and Drying:
After coating, the workpiece is thoroughly rinsed and dried.
Result:
This creates a durable, high-gloss or matte chromium surface, which effectively protects the workpiece from corrosion, abrasion, and chemical influences.
4. Benefits of Chromium Electroplating at a Glance
-Durability: Protection against corrosion, abrasion, and weathering extends the lifespan of components.
-High-Quality Appearance: A mirrored or matte surface gives the product a high-quality, appealing look.
-Scratch Resistance: The chromium layer protects against mechanical damage in daily use.
-Easy Cleaning: Chromium-plated surfaces are hygienic and easy to maintain.
-Economical: Long-term cost-effective due to reduced maintenance and spare part costs.
-Wide Range of Applications: Suitable for shopfitting, furniture industry, hotel & catering equipment, and design components.
5. A Practical Example – Successful Application in Industry
Initial Situation
A retailer requires durable and visually appealing shopfitting systems to present products in a high-quality manner and create an inviting shopping atmosphere. The systems must be robust, easy to clean, and resistant to daily wear and tear.
Approach
As a manufacturer of shopfitting systems, LMV Metalltechnik GmbH uses chromium electroplating to provide their shelving systems, product displays, and counter elements with a high-gloss or matte, durable surface. After thorough pre-treatment, the metal components are uniformly coated in the in-house chromium plating process, resulting in a hard-wearing and visually appealing surface.
Result
The chromium-plated shopfitting elements are scratch-resistant, corrosion-resistant, and easy to maintain. Even with high customer traffic and frequent cleaning, they retain their original surface and contribute to making the displayed goods appear high-quality and creating a pleasant shopping atmosphere.
Added Value for the Customer
The retailer benefits from durable, aesthetically pleasing shopfitting systems, which, through LMV’s chromium electroplating in Lauingen, offer both functional and visual advantages. This enhances sales areas, extends the lifespan of the systems, and sustainably protects the investment.
