A multitude of new regulations reduce the number of hard chromium plating plants worldwide, but hydraulic cylinders are traditionally hard chromium plated. Oerlikon Metco has a solution to your challenge.

Cost-Effective Alternative to Hard Chromium Plating

It is the rule of the economy — and a challenge for OEMs and MROs (Maintenance and Repair Operations) companies in the mining business: Hard chromium plating costs increase as global demand increases and supply decreases. The industry requires new application techniques, processes and materials to protect, at reasonable cost, hydraulic cylinders from:

  • Corrosion
  • Side loading
  • Shock loading conditions
  • High vibration
  • High and low operating temperatures
  • Sliding abrasion

As a full-service provider with experts in coating solutions for hydraulic cylinders, Oerlikon Metco has developed a unique portfolio of materials and processes that are cost-effective solutions for this special application. Processes such as gas or liquid High Velocity Oxygen Fuel (HVOF) Spray, and Electric Arc Wire (EAW) Spray processes have been further developed and refined to meet the technical challenges in the mining industry.

We provide our customers a combined offering of high technology materials and state-of-the-art equipment, to ensure the coatings achieve the targeted performance.

Key HVOF materials:

  • WOKA 7103
  • WOKA 7203

Key EAW Materials

  • Metco 8280
  • Metco 8293
  • Metco 8453
