High Friction Coatings

Demand for high friction surfaces is growing rapidly in a wide number of industries.  Our Partner has developed the most extensive selection of high friction composite electroless nickel coatings to serve the needs of applications in the automotive, aerospace, wind energy, turbine, machining, robotics, medical, dental, paper and many other industries.

The high friction coatings are used on shims, flanges, bolts, connectors, clamps, collets, joints, belt applications, and more.  These coatings work to increase the friction, grip, torque, energy transfer and other critical properties of these applications.  This is in addition to all the features inherent in all our coatings, including:
 

• Exceptional hardness
• Corrosion resistance
• Perfect conformity to complex geometries
• Wear, abrasion, impact, and high temperature resistance
• Applicability to many common metals and alloys
• Coverage of entire surfaces or selected critical areas

These features allow: 

• Greater reliability and consistent performance
• Increased lifetime and decreased maintenance-related downtime
• Opportunity to re-engineer products with lighter weight and/or less expensive materials
• Energy savings

Our high friction coatings all work thanks to the roughness achieved by the protrusion of hard particles such as diamond, silicon carbide or others through the surface of an electroless nickel coating as seen in the following SEM photograph.  These hard particles then grip into the mating surface.  We can vary the roughness by adjusting the size, shape, and density of the particles on the surface.  

Additional versions available from Electroless Technology AG to meet the specific needs of unique applications
