Hard Chrome Coating
Precision Hard Chrome Coating Services
Hard chrome coating is a durable and corrosion-protective metal finishing solution. We offer two unique processes for specialty applications. Our most effective treatment is the DyClad process. We also use titanium nitride under the trade name DyCro-Tuff. That process involves using a hybrid micro-crack hard chrome solution with a proprietary impregnated dry lubricant to create a mirror finish and durable wear surface.
Hale Performance Coatings employs highly skilled employees who are well-versed in optimizing chrome adhesion to provide uniform thickness at a fast rate. We rigorously inspect each component before chroming to confirm that your equipment is compatible with the process.
What is Hard Chrome Coating?
Also known as industrial chrome and engineering chrome, this finish uses electroplating to apply pure chromium to a metal surface to increase wear resistance and hardness. A thin layer is applied to create a protective barrier, which is useful in manufacturing and engineering equipment. It’s manufactured to enhance part function, not aesthetics like decorative chrome.
Benefits of Using Hard Chrome Plating
The coating process protects substrates against abrasion and mechanical wear, which is crucial in high-stress environments. Hard chrome plating also prevents chemical, moisture and gas corrosion and can withstand high temperatures. Once plated, your components may be honed to a specific measurement to reduce friction in sliding and rotating parts.
Additional advantages of hard chrome plating include:
- Longer tool/part life: You can increase the longevity by up to 300% and save money by cutting downtime and equipment repair costs.
- Higher lubricity: In mold and die applications, chroming eases product release and eliminates or reduces galling, seizing and wearing due to friction.
- Greater hardness: Chrome plating hardness exceeds Rockwell C65, which helps prevent abrasion, corrosion and erosion from environmental and chemical forces.
- High-performance stripping: Unlike other surface treatments, chrome plating can be removed. That allows you to repair or change the existing piece and save on replacement costs.
- Better machinability: You can machine heavy deposits and extend the life of each chromed piece.
Our Process
Surface Cleaning and Inspection
Each metal piece must be thoroughly inspected and cleaned before being chrome-plated. We use degreasing, blasting and chemical treatments to remove grime and create a smooth surface. Proper preparation is essential for achieving a long-lasting bond.
Precision Electroplating
The process begins with submerging a piece of metal in a chromic acid bath. An electric current is applied to the solution, causing the chromium ions to adhere to the metal surface. The duration varies depending on the desired thickness.
Post-Coating Inspection
We rinse the substrate after electroplating to remove acid and chemical residue. Our final inspection includes a thickness test using a micrometer and visual evaluation to check for proper adhesion, cracks and uneven plating.
Hard Chrome Coating vs. Other Coating Methods
Compared to other traditional coating methods, hard chrome coating offers exceptional hardness that’s ideal for high-wear parts. It can last longer under mechanical stress, making it ideal for shafts, bearings and dies.
You can refurbish worn-out parts and tools with hard chrome plating and protect your bottom line. Other coating methods may require multiple applications to achieve the same resistance. The mirror-like finish also sets chrome apart from other plating options. Alternative coatings typically require grinding and buffing to create a smooth surface.
Hale Performance Coatings excels at stripping hard chrome and returning your parts in prime condition, saving you both time and money. That’s especially cost-effective for large productions.

Hard Chrome Coating FAQs
How thick is a typical hard chrome layer?
Hard chrome plating thickness varies from 20 to 1,000 microns.
Can hard chrome be applied over worn parts?
Yes. It’s an effective method for revitalizing different metal components and tools, especially those used in high-stress applications.
Is it safe for food-grade applications?
Hard chrome plating is generally not recommended for food-grade applications.
Can it be stripped and recoated?
Yes.
