Ceraplate Coating

Ceraplate Coating

Hydraulic cylinder piston rods may suffer reduced life when installed in aggressive environments for example: hydroelectric plants, marine & offshore equipment, mining industry, paper mill and printing industry, etc.

As an alternative to conventional surface protection systems such as hardening, nitriding, hard chrome plating and nickel plating, HUNGER developed Ceraplate®, a coating technology which significantly improves surface protection against chemical attack and mechanical wear and tear.

Technical details

• Thermal sprayed Ni/Cr base layer and Cr₂CO₃/TiO₂ top layer
• Layer thickness: base layer approx. 150 µm and top layer approx. 200 µm
• Hardness of top layer 950 HV to 1.050 HV
• Surface superfinished to Ra = 0,15 µm
• For piston rods up to a diameter of 1,500 mm and an length of 20 m

Properties

Increased resistance to corrosion and chemical attack and increased resistance to abrasive an erosive wear and tear (Corrosion test according to DIN EN ISO 9227, 1,500 hours)
