Sea Dock Hydraulic Rods Hard Chrome Replacement

Thermal spray applications that can be completed with Kermetico HVAF technology cannot be accomplished as well with traditional thermal spray processes. One particular area is the replacement of hard chrome plating on hydraulic rods.

Traditional coatings and hydraulics have never worked long enough. Even with a sealer, the porosity eventually allows the hydraulic fluid under pressure to penetrate the coating. Once the pressurized fluid hits the substrate, it spreads out under the coating and lifts it off.

Kermetico coated about 30 hydraulic rods used at a local refinery on their dock cranes. They had been getting only six months out of the chrome plated rods. Kermetico coated them with HVAF WCCoCr 86-10-4. The first ones that were sprayed have been in service for over five years. A report of a visual inspection about six months ago was, “They still pretty much look like they did when we first put them in.”
