Anti Friction Coating
What is lubricating coating?
It maintains semi-permanent performance by forming a lubricating film in a solid state on friction areas where friction and wear occur. This lubricating film is firmly attached to the part surface and cannot fall off, so unlike grease or oil lubrication, it does not contaminate the surrounding parts.
Lubricating coating agents are largely composed of solid lubricants, solvents, and binders.
-
Solid lubricant: It is a practical ingredient that acts as a lubricant and can be selected depending on friction conditions and environment.
-
Solvent: It is used for liquefaction (easy to apply) before drying, and when dried, it vaporizes to form a coating layer.
-
Binder: It is an ingredient that attaches solid lubricant to the base material and varies depending on the shape and material of the application area.
Additional components include fillers (e.g. colorants, etc.) or additives (e.g. corrosion inhibitors, etc.).
Lubricating coating
-
Ensures clean lubrication.
-
Improves starting torque with oil or grease lubrication.
-
Protects against wear and ensures continuous operation without stick slip even at low speeds.
-
Provides permanent lubrication without the need for relubrication, even at low sliding speeds or short sliding distances.
-
Prevents corrosion.
-
Provides efficient lubrication even when exposed to reactive or corrosive substances, UV and X-rays, under vacuum conditions or at low and high temperatures.
-
Facilitates assembly and disassembly of close-tolerance components
-
Ensures clear tightening torque and preload forces on screw connections.
-
Suitable for coating multiple materials.
-
Precise application methods enable economical solutions.
Lubricating coatings are widely used not only in the aerospace industry, but also in automotive, bearing and precision engineering fields. It provides permanent lubrication for a variety of components including bearings, locking devices, hinges, screws and bolts, valves, pistons, guide rails, and seals.
Coating types
The lubricating coating can be designed in various ways depending on the solid lubricant, binder, and solvent. Based on operating conditions such as applied parts material and driving environment, it is recommended to select an optimized coating type through consultation with our lubrication coating expert to meet customer requirements such as friction resistance, low torque, insulation, and rust prevention. For lubricating coating, not only the selection of coating agent but also the line design for uniform application is important. DOAH, a lubricating coating expert, will help you select coating agent to finally apply it.
