PTFE Nickel Electroplating – Advanced Surface Treatment
PTFE Nickel Electroplating is an innovative surface treatment that combines the advantages of nickel electroplating with the inclusion of PTFE (Polytetrafluoroethylene). This treatment offers exceptional tribological characteristics, such as low friction and excellent wear resistance, while maintaining optimal corrosion protection. This solution effectively solves wear and friction problems while benefiting from the unique properties of each material.
Benefits
– Improved friction: Significantly reduced friction, extending component life and improving efficiency.
– Anti-adhesion: Prevents the adhesion of impurities and dirt, facilitating cleaning of treated parts.
– Anti-corrosion: Provides long-lasting protection against chemical attack and corrosion, even in harsh environments.
– Anti-friction: The low coefficient of friction of the integrated PTFE reduces wear and improves system performance.
– Thin coatings: Homogeneous deposit that adapts to the geometry of the part, with a regular and uniform layer. precise.
Features
– Zero-current process: This treatment is performed without the use of electrical current, allowing for uniform and precise application.
– Anti-static layer: The coating is non-insulating, maintaining optimal electrical conductivity.
– Electrical conductivity: The electrical conductivity ranges from 130 to 200 ohms, suitable for various industrial applications.
– Tribological properties: The combination of nickel-phosphorus and PTFE provides excellent lubrication and reduces wear.
– Low friction: The coefficient of friction is reduced to 0.15 in static conditions and 0.10 in dynamic conditions, providing exceptional sliding performance.
– Durability and strength: The resulting coating is as wear-resistant as hard chrome plating, with a hardness of 500 to 700 HV.
– Operating temperature: Resistant to extreme temperatures, from -240° to +250°C.
– Easy cleaning: Thanks to the non-stick effect, dirt does not adhere to the treated surfaces, making them easier to maintain.
– Coating thickness : The recommended thickness varies between 20 and 40 microns, with a maximum of 80 microns.
Detailed Features:
– PTFE Particles: PTFE particles, measuring between 0.2 and 0.3 microns, are uniformly dispersed throughout the nickel-phosphorus layer, ensuring optimal lubrication.
– Melting Point: Nickel has a melting point of 800°C, while PTFE melts at approximately 270°C, ensuring good thermal stability.
– Compatibility: The treatment can be applied to all types of base materials compatible with the galvanic or autocatalytic treatment.
Typical application
PTFE Nickel Electroless is particularly suitable for applications where wear resistance, friction reduction, and corrosion protection are essential. Here are some examples of its applications:
– Pump components: Pump shafts, stators, sleeves, bushings.
– Movement and control equipment: Heating plates, feeders, splined shafts, adjusting screws.
– Precision components: Grippers, cups, pistons, cylinders.
Conclusion:
PTFE Chemical Nickel is an advanced surface treatment that combines the best features of nickel and PTFE materials. It offers an effective solution for improving tribological performance, increasing part life, and reducing maintenance costs in a wide range of industries.
