Surface treatments
Some components require chemical or electrolytic surface treatments, sometimes in combination with thermal spraying or hardfacing.These treatments increase the corrosion resistance, wear resistance, or chemical inertia of components, and are often chosen for applications in aggressive environments such as offshore, chemical, or food industries.
How Does the Process Work?
Depending on the material and the desired end characteristics, we choose the right technique:
- Galvanic processes (such as hard chrome plating or nickel plating) build up a metal layer through electrolysis.
- Chemical processes (such as chemical nickel) work without electricity and ensure an even coating.
- Anodization changes the surface of aluminum through electrochemical oxidation.
- Rubber coatings are physically applied and profiled if necessary.
- Blasting or glass beading is used as a pre-treatment or to increase roughness.
These techniques can be performed separately or in combination, and we often provide follow-up treatments such as grinding or polishing to achieve the desired end result.
Hard chrome
- Technical chrome coating (30 to 2,000 µm)
- Very hard (up to 1,100 Vickers)
- High-gloss finish possible through precision grinding
Nickel-plating
- Electrolytic or autocatalytic (chemical nickel)
- Corrosion resistant, often used as an undercoat or topcoat
Hard anodizing
- For aluminum components
- Oxidation layer via electrochemical process
Rubber coatings
- Frequently applied to rolls
- FDA-approved types for the food or pharmaceutical sector
Blasting & glass beading
- Increases roughness for adhesion or functional purposes
- Grit or pearl blasting depending on application
Capacity
- Parts up to Ø 1,000 mm, length up to 6,000 mm (depending on process)
- In-house grinding and measuring capacity for post-treatment
- Large stock of nickel, chrome, and anodizing chemicals
- Profiled rubber layers and custom finishes
