Electroless nickel coating with embedded hard particles

In mechanical engineering, electroless nickel dispersion coatings serve to increase or reduce friction, minimize wear and protect the aesthetic value of surfaces. For example, they can be used to reduce maintenance frequency and allow infinite positioning accuracy in CNC machines, marine engineering, wind and water power generators, turbines or profile machine manufacturing. 3M™ offers various electroless nickel composite coatings that are produced under certified processes, for example to ISO 9001, ISO 14001 and TS 16949.

Successfully Employed Worldwide

Custom solutions with 3M™ coatings are used throughout the world. They are characterized by:

  • Homogeneous particle distribution
  • Dimensional accuracy of the layer thickness
  • Contour retaining coating of the substrate
  • Reproducibility of the coating
  • Tracing of batches
  • Extremely short lead times
  • Delivery reliability

Manufacturing

3M™ friction enhancing coatings consist of a chemical nickel matrix with defined diamond particles embedded during the coating process. The coated parts are than heat treated to anchoring the diamonds in the nickel matrix.

Friction enhancing coatings

3M™’s mission is to offer the ideal solution for any customer requirement. Besides tried-and-tested 3M™ friction-enhancing coatings, our specialists are also continously developing customized designs and solutions for frictional joint elements. With our extensive industrial facilities and profound experience in this field, we can produce innovations and solutions that can be rapidly commercially exploited.

3M™ Friction enhancing coatings for components

Wherever components must be reliably joined together to transmit forces and torques, 3M™ Friction-Enhancing Coatings provide simple, reliable and technically mature solutions. The 3M™ Friction Shim is a metal foil with a friction-enhancing coating based on electroless nickel with embedded hard material (= electroless nickel composites surface).

Properties

3M™ Electroless Nickel Composite Coatings are characterized by:

  • Microscale interlocking with the joint surfaces
  • Adjustable and reproducible surface properties
  • Contour retaining coating of the substrate
  • Enables weight and packaging-optimized designs
  • Static friction increase up to a factor of 4
  • Easy assembly and resassembly

Wear Protection Coatings

3M™ Technical Ceramics has a long tradition of producing anti wear coatings.

3M™ Technical Ceramics offers complete or partial coating of components or combing wires with electroless nickel dispersions with the controlled incorporation of inorganic hard particles. Selection of the incorporated substances for particular applications is one of 3M™ Technical Ceramics core competences as a result of its extensive experience in grain manufacturing, fractionating and classification.

The specified properties are continuously monitored and the processes certified.

Properties

  • Homogenity of inclusions
  • Dimensional accuracy of the coating thickness
  • The coating maintains the exact profile of the substrate
  • Reproducibility of the coating

3M™ Technical Ceramics does not process chromiumcontaining systems, which can be hazardous to health. The alternative tried-and-tested binary alloys with incorporated substances can provide tribological properties that are identical, or even superior to such systems.
