Hard chrome plating, Chrome composite coating, ChromePlus

Hard chrome plating

Hard chrome plating, is carried out by electroplating in single or multiple layers. Piston rods up to length of up to 20 meters and diameters up to 1,000 mm are hard chrome plated. For application in more aggressive enviroments our alternative coating should be considered.

Technical facts

  • Electro plated piston rod coating
  • Layer thickness of 20 μm up to 100 μm
  • Dual layer chrome plating possible
  • Hardness of the chrome plating from 800 HV to 950 HV
  • Surface finish up to Ra 0,15 μm

Properties

  • Standard corrosion protection and functional layer

Fields of application

  • Hydraulic cylinders in general machine tools, mobile cranes, construction machinery, printing industry etc.

Chrome composite coating

To improve the corrosion protection properties it is possible to combine the hard chrome layer with a second layer underneath the chrome. In this case a separation of the functions of the layers is made, the hard chrome layer functions as a wear and tear protection, the base layer functions as a corrosion barrier. Usually the base layer is made of a galvanized Nickel.

ChromePlus

The ChromePlus plating is a laser welded coating which consists of a metal matrix with embedded chrome carbides. By using the laser-welding very thin layers can be applied with very high efficiency. Because of the absolute pore and crack free coating very good corrosion protection properties can be guaranteed.

Technical facts

  • Laser cladded piston rod coating
  • Layer thickness of 20 μm up to 100 μm
  • Chrome-VI free application process
  • Hardness of the ChromePlus layer approx. 600 HV
  • Surface finish up to Ra 0,15 μm

Properties

  • Standard corrosion protection and wear protection

Fields of application

  • Hydraulic cylinders in general machine tools, mobile cranes, construction machinery, printing industry etc.
