Professional Chromium Oxide Plasma Spraying (Cr₂O₃) - Extreme Protection for Your Components

In today's industry, where every detail counts, the service life and precision of machine parts determine the continuity of production and the profitability of the entire enterprise.

We offer an advanced surface engineering service: Plasma spraying with chromium oxide (Cr₂O₃).. This is a state-of-the-art technology that allows us to apply an ultra-hard, abrasion-resistant and chemically inert ceramic layer to key machine components. Instead of costly replacement of worn parts, we offer a solution that not only restores their original functionality, but significantly surpasses it, protecting your investment for years to come.

Our technology is particularly applicable in industries where the highest precision and resistance are required - from flexographic printing to general heavy industry applications. Chromium oxide plasma spraying (plasma spray) is widely used in a variety of industries such as aerospace, energy, automotive and chemical, where resistance to wear, corrosion and extreme operating environments is crucial.

This technology allows the application of both ceramic coatings and metal coatings, as well as the spraying of metals and their alloys, making it possible to obtain coatings with high wear and corrosion resistance. In the plasma spray process, ionized gas (plasma) at very high temperatures allows precise spraying (spray) of coatings of the highest quality on a variety of substrates. When choosing this technology, technical considerations such as the type of material, operating conditions and specific requirements of the working environment should be taken into account to ensure optimal coating performance and durability.

By using state-of-the-art plasma spray systems, we guarantee repeatability, superior quality and excellent adhesion of the coating to the substrate, creating an insurmountable protective barrier to the elements.

Key features of chromium oxide plasma spraying

  • Highest Abrasion Resistance: Chromium oxide is one of the hardest ceramic materials. Our coating creates a surface with extreme resistance to abrasive wear, dramatically extending the life of shafts, bushings, piston rods and other parts exposed to intense friction. We use wear-resistant coatings, especially carbide and ceramic coatings, using carbide, metal carbide, chromium carbide and tungsten carbide, as well as tungsten carbide-based coatings that provide exceptional hardness and wear resistance even under harsh operating conditions.

  • Ideal Surface for Laser Engraving: Chromium oxide coatings have excellent melting properties and a dense structure, making them an ideal base material for anilox rollers. They enable precise laser engraving of intricate cells, which is key to achieving the highest print quality. In spraying technology, we also use metal coatings, such as nickel, and ceramic coatings made of oxides such as aluminum oxide and titanium oxide, which show high corrosion and abrasion resistance.

  • Regeneration and New Applications: Our service is not only to protect new components. We also specialize in remanufacturing used parts. Plasma spraying with chromium oxide is an economical alternative to buying new, expensive components, allowing you to restore them to full efficiency and significantly increase their performance.

Applications of Plasma Spray Technology

Plasma spraying with chromium oxide is a dedicated solution for the most demanding industrial applications.

● Printing Industry - Anilox Rollers:

This is the main and most critical application of our technology. The Cr₂O₃ coating is the industry standard for anilox rollers and sleeves in flexographic printing. Its hardness protects against wear and tear caused by squeegees, and its precise structure allows for laser engraving of cells with high linearity, ensuring optimal and reproducible ink transfer.

● Machinery and Heavy Industry:

Chrome oxide coatings are ideal for use on machine components where there is intense friction and risk of corrosion. Examples of applications include:

  • Hydraulic pistons and cylinders
  • Shafts and pivots
  • Protective bushings and pan
  • Pump and valve components
  • Slides and other sliding parts

Plasma Spraying Technology and Application Process :

Our technological process has been optimized to ensure the highest quality and durability of the coating. It consists of several key steps:

1 Surface Preparation:

This is a critical step that determines adhesion. The component to be coated is thoroughly cleaned and abrasive blasted to achieve the proper surface roughness and activation.

2 Chromium Oxide Plasma Spraying:

At the heart of the process is a plasma yoke that generates a plasma jet of extremely high temperature. Into this stream is introduced powdered chromium oxide (Cr₂O₃), which melts and is sprayed onto the prepared surface of the workpiece at tremendous speed. The particles form a dense ceramic layer that is strongly bonded to the substrate.

3 Finishing Treatment:

After the coating is applied, the part is subjected to precision grinding and polishing. This process allows to achieve the required surface smoothness (low Ra value) and final dimensions with strict tolerances.

Q&A- frequently asked questions about plasma showers

It is a surface engineering service that applies a hard and resistant ceramic layer of chromium oxide (Cr₂O₃) to machine components to protect or regenerate them.

Powdered pure chromium oxide (Cr₂O₃) is used to create the coating.

The coating is characterized by extreme abrasion resistance, high hardness, low porosity, chemical inertness and excellent adhesion to the substrate.

The technology is mainly used in the printing industry (anilox rollers) as well as in the engineering and heavy industry.

The service can cover anilox shafts, hydraulic piston rods and cylinders, shafts, journals, protective bushings, pan, pump and valve components and guides, among others.

The service includes both the protection of new components and the remanufacturing of worn parts, which is an economical alternative to buying new components.

The process consists of three stages: surface preparation (cleaning, abrasive blasting), actual plasma spraying, and finishing treatment (grinding, polishing).

Because its hardness protects against wear and tear from the squeegee, and its dense texture allows precise laser engraving of cells for optimal and reproducible ink transfer.
