Wear and Corrosion Protection for Hydraulics
Cylinders, piston rods, valves and housings in hydraulic systems are exposed to high wear, fluctuating pressures and often harsh operating conditions. As your development partner, we tailor wear and corrosion protection specifically to your functional surfaces and components.
Overview
Suitable Processes for Hydraulics
Electroless Nickel achieves hardness values above 1000 HV through thermal post-treatment and deposits uniformly regardless of component geometry – important for piston rods, valve spindles and other closely toleranced functional surfaces.
For housings, flanges and connecting elements made of steel, Zinc-Nickel offers reliable electroplated corrosion protection; for aluminium components, Passivation performs the same task.
Typical challenges
What Hydraulics Manufacturers & Suppliers Come to Us For
Wear-resistant, closely toleranced functional surfaces on piston rods and valve spindles
Piston rods, valve spindles and other sliding functional surfaces are permanently exposed to friction and fluctuating loads, often with tight manufacturing tolerances. Electroless Nickel achieves hardness values above 1000 HV through targeted thermal post-treatment while depositing uniformly without an external current – even on complex geometries.
Solution: Electroless Nickel
Corrosion protection for housings, flanges and connecting elements made of steel
Hydraulic housings and connecting elements are often exposed to moisture, fluctuating operating media and harsh operating environments. Zinc-Nickel offers one of the highest-performing electroplated corrosion protection systems for this.
Solution: Zinc-Nickel
Corrosion protection and pretreatment for aluminium components
Weight-optimised hydraulic components made of aluminium require a defined, reproducible surface as corrosion protection and as preparation for assembly or further processing. Passivation replaces the uneven natural oxide layer with a defined, thin, durable conversion coating.
Solution: Passivation of Aluminium
Reproducible quality for demanding leak-tightness and functional requirements
Hydraulic systems operate at high pressures – even small deviations in coating thickness can affect leak-tightness and function. Documented process monitoring and recurring inspections ensure the required reproducibility across every batch.
Solution: Quality inspections
Quality & process reliability
Documented Processes for Leak-Tight, Wear-Resistant Components
For every component, we align the process control with the required functional and leak-tightness requirements. Our quality management system and ongoing product and process monitoring ensure the required reproducibility.
Our management systems are certified to IATF 16949, ISO 14001 and ISO 50001. The certificates document the respective scopes. More on quality and environment.
