Enthone has introduced Ankor Hydraulics hard chrome process. Specially engineered for the hydraulics/fluid power market, the process delivers exceptional corrosion resistance, while offering a more sustainable alternative versus other high efficiency, etch-free hard chrome processes currently available today. AnkorHydraulics eliminates failures related to microporosity and nodules to ensure the highest level of performance at a lower cost of ownership.


Specifically, AnkorHydraulics imparts enhanced micro crack, pore-free chrome deposits on steel. Compared to competitive, high efficiency hard chrome processes, AnkorHydraulics is proven to increase productivity by up to 25%, due to its exceptional metal distribution. More thickness is achieved on the weakest spot of the hydraulic bar in less time, while reducing electricity and chemistry consumption. In addition to steel, AnkorHydraulics offers rapid deposition of hard chromium on stainless steel, induction hardened steel, chrome-on-chrome and nickel underlayers.


AnkorHydraulics includes a foamless, PFOS-free mist suppressant as an integral part of the hard chrome technology. The suppressant component eliminates air borne emission, and contributes towards the smoothness, brightness, hardness and robustness of the process, while enabling easy chrome-on-chrome adhesion and resistance to current interruptions.


“AnkorHydraulics is a significant advancement for sustainable hard chrome technology," said Helmut Horsthemke, Global Product Manager - Enthone Wear Resistant Coatings. "The process minimizes drag-out, slows metal impurity build-up, reduces cooling demand, as well as delivers best-in-class current efficiency, low plating voltage, over-plate reduction, reduced equipment and anode maintenance. All these attributes minimize emissions, waste and CO2 footprint.”


AnkorHydraulics is designed for horizontal hoist and continuous lines, as well as manual vertical operation. Specially engineered for plating hydraulics cylinders, as well as chrome plated bars and tubes, further information on AnkorHydraulics is available by contacting A fact sheet detailing the mist suppressant is available by clicking HERE.
