Hard Chrome Plating

Tre-P is one of the best companies in the world, formed by chroming metal specialists who deal with the Chrome Plating process, which is a technique of electroplating a layer of chromium onto to a steel object.

The functional Hard-Chromium plating is not decorative, guarantees wear corrosion resistance, this process also increases surface hardness above standards.

The Hard Chrome Plating is used to reduce friction, improve durability trough abrasion tolerance and wear resistance, minimizing the seize of each part, expanding chemical inertness to include a broader set of specifications, especially oxidation resistance, a winning quality.

Hard Chrome Plating characteristics

This type of special plating is characterized by its hardness, it measures between 950 to 1200 HV (69 to 72 HRC).

The Hard Chroming is thicker than the decorative chrome, with standard thickness ranging from 15µm to 35µm, but it can be an order of magnitude thickness for extreme wear resistance requirements.

The Hard Chrome plating is subject to different types of quality requirements depending on the application it’s used for.

Tre P’s chrome is a fluoride free hard chromium process with a high current efficiency. Our hard chrome can be used for different applications, according to the use of the part we adjust the bath concentration and the deposition parameters.

The advantages of Tre P’s hard chrome plating

The Tre P’s chrome process has the following significant advantages:

  • Superior corrosion resistance compared to other chrome processes, especially for shock absorber and hydraulic rods.
  • Excellent deposition efficiency. Deposition times can be shortened by about 30 % compared to a conventional sulphate bath.
  • Reduced electricity costs by about 30 % compared to conventional sulfate baths.
  • An etch behaviour on steel that is comparable to conventional electrolytes.
  • Highly micro-cracked deposit that enhances corrosion resistance of the plated article.
  • Bright, hard deposit, with hardness >950 HV 0.1 (950 – 1200 HV 0.1).
  • Highly resistant to abrasion.
  • Good throwing power and metal distribution.
  • More stable catalyst and bath performance than mixed catalyst electrolytes.
  • Wider operating window than comparable processes.
