Hard Chrome Compound Plating

Applications: Hydraulic cylinders with increased corrosion protection requirements in general engineering, hydro electric construction, construction machines, printing machines, chemical industry etc. The Hunger hard chromium compound layer consists of different materials and layers. Base layer: HVOF sprayed, thickness approx. 200 µm Top layer: galvanic single or multiple chromium plating 30 to 100 µm mechanical surfache features such as a conventional hard chromium layer additionally, higher resistance against corrosion HVOF NiCr- layer (200 µm) with a porosity of < 1 % layer thickness of the base layer 200 µm, of the top layer 50 µm hardness of the chromium layer 800 HV to 900 HV surface finishing by super finishing Ra 0.1 - 0.15 µm for piston rods up to a diameter of 600 mm and a length of 17.000 mm Features: Improved corrosion resistance as compared to hard chromium (corrosion protection proof according to DIN 50021-SS 1000) Option: with integrated position measuring system CIPS
