minimum coefficients of friction
what are anti-friction coatings?
Are your components constantly subjected to frictional forces? Our surface technology experts have intensively dealt with this topic. The result: durable anti-friction coating for a wide variety of applications. Thanks to our professional coatings, the material underneath the surface remains intact and protected for a long time. Robust anti-friction coatings by Aalberts surface technologies will not let you down. Dry lubrication has many advantages over conventional lubricants like oil or grease. On the one hand, it is possible to significantly increase the coefficients of friction and the gliding properties; on the other hand, we have prolonged the component life span. What is more, continuous lubrication is maintenance-free, no matter how high the loads.
high-quality anti-friction coating for steel, aluminum or other materials
Anti-friction coatings are dry lubricants that reduce friction and wear. The fact that these coatings are also able to avoid noises makes them suitable for use on any kind of material, which is why anti-friction coatings are not intended exclusively for steel and aluminum. At Aalberts surface technologies, they are also applied to polyamide, for example. Depending on the respective process variant, we can finish technically interesting base materials with functional anti-friction coatings:
- Light metals
Our entire range of coating materials is water-soluble and can be applied using different coating techniques. Our experts will customize the respective process to fit your individual needs. The following aspects will be taken into account: the geometry and the quantity, the properties of the liquid coating material (e.g. single- or multi-component system) and the requirements to be fulfilled by the finished coating. Considering your wishes, we will make sure that the anti-friction coating will be characterized by an effective combination of wear protection, dry lubrication, non-stick properties and corrosion protection.
Below you will find a detailed description of our effective anti-friction coatings. Please do not hesitate to get in touch should you have any further questions about the presented surface finishes.
effective anti-friction coating for steel
Polymer and fluoropolymer coatings have proven very effective when it comes to making sure that steel components feature good non-stick and gliding properties as well as wear resistance. Applied using a special infusion method, the high-performance plastic surface becomes firmly anchored in the substrate. For increased wear protection, we apply additional interlayers which permanently protect steel against wear and oxidation. Not only is this treatment highly recommendable for steel and stainless steel, but the gliding and non-stick properties are also ideal for aluminum, copper, ceramics and plastics.
Below you will find an overview with detailed information about our different anti-friction coatings.
antifricor®, GLISS-COAT® and HMF® – our premium-class high-performance dry lubricants
When components are constantly subjected to friction, the coefficient of friction increases over time, irrespective of whether or not the parts are sufficiently lubricated. This results in disrupted processes and shorter component service lives.
antifricor® – anti-friction coating for ferrous materials
With antifricor®, Aalberts surface treatment offers a multi-functional dry lubricant for components whose surfaces move against each other. It allows for optimized friction, wear, corrosion and lubrication
antifricor® is suitable for all applications where frictional forces caused by load have a negative impact on the service life of components, which is why this type of anti-friction coating is used by almost all renowned automobile manufacturers. Hinges, door locks, door check straps, door handles, adjustment systems, press fittings and other screw connections made of iron are typically coated with antifricor®.
GLISS-COAT® – custom anti-friction coating
GLISS-COAT® describes a range of dry lubricant coatings developed by Aalberts surface treatment. While these functional anti-friction coatings reduce friction and wear, they also avoid squeaking and creaking noises. Once applied, most of the GLISS-COAT® coatings are matte dark gray or black. When pressurized, they take on a shiny appearance and their coefficient of friction decreases.
Depending on the process and your company’s specific requirements, the coating is either sprayed on or applied in immersion centrifuges. Both the coating thicknesses and their tolerances are assured by largely automated application methods. GLISS-COAT® systems consist of organic binding systems which, depending on the process, are filled with different solid lubricants. Depending on the process, GLISS-COAT® coatings are either sprayed on or applied in coating drums. The thickness tolerances of these functional coatings may be adjusted. Depending on the process, the adjustment range is between +/- 10 µm and/or +/- 15 µm. Both the thicknesses and their tolerances are assured by largely automated application methods. Depending on the method used, it is possible to coat all technically relevant metals, light metals and plastics. However, we are always willing to go the extra mile for our customers and to think outside of the box. We have developed, for example, GLISS-COAT® coatings for special applications: Our range of successfully coated materials now also includes paper, fleece, plastic and metal foils as well as ceramics. This needs-based modification is possible, because GLISS-COAT® coating systems are our in-house developments.
Moving vehicle interior components, e.g.
Compression springs for shock-absorbing systems
Seat locking mechanisms
GLISS-COAT® coating systems are primarily used in the automotive industry, in analytical applications and in lignite mining. However, this type of coating is also frequently used as surface finish in medical engineering, the furniture industry, solar engineering and wind energy engineering.
GLISS-COAT® FLOCK – for improved shock absorption
GLISS-COAT® FLOCK is a functional anti-friction coating consisting of a combination of low-friction adhesive and polymer fibers. The first step of this functional coating technique involves the application of GLISS-COAT® adhesive to the workpiece surface. After that, the polymer fibers are embedded in the coating while it is still wet.
GLISS-COAT® FLOCK coatings aim at increasing the component’s capacity to absorb shocks and eliminate noises. Thanks to special additives, the coating system moves toward the fiber tips. These movements within the tribological system create a lubricant film on the individual fibers so that the wear behavior improves significantly. A special post-treatment can further enhance this effect and optimize the run-in behavior. Apart from that, the coating has positive surface properties, such as flexible tolerance compensation, gliding properties and corrosion resistance.
GLISS-COAT® FLOCK can be applied to phosphate, anodized and sand-blasted metal surfaces as well as to plastics. Partial coatings, e.g. on the exterior of a spring, are feasible as well.
In general, it is possible to coat the following components:
- All kinds of springs
- Locking pins
- Sliding mechanisms
- Guide rails
HMF® – anti-friction coating with a unique micro finish
HMF® is a multi-layer coating process suitable for almost all metallic alloys. A series of independent processing steps creates a very hard, ultra-smooth, reflective or glossy micro finish. The HMF® coating process ensures permanent dry lubrication accompanied by improved surface hardness.
HMF® coatings are used, inter alia, in the following industries: cosmetics industry, plastic injection molding and extrusion, aviation, paper, film and foil production, tobacco industry, packaging industry. Typical components include calender rolls, pistons, ball valves and seats, cams, embossing tools, slides, locking mechanisms or funnels.
