DAOLER Friction Coating: Eliminating Insufficient Friction, Unlocking Efficient and Reliable Connections
In numerous critical mechanical connections, insufficient friction is an insidious threat to performance and reliability. When the coefficient of friction fails to meet design requirements, a cascade of challenging issues emerges, constraining equipment efficiency and service life:
Slippage and Performance Loss: Power transmission efficiency is significantly compromised, and torque cannot be effectively transferred, resulting in energy waste, degraded performance, and even functional failure.
Frictional Wear / Fretting Corrosion: Minute relative motion (fretting) at the contact interface induces continuous wear and corrosion, accelerating material degradation and ultimately leading to joint loosening or fatigue fracture.
Complex Assembly Processes: To ensure adequate clamping force, additional fasteners, elaborate preload adjustment procedures, or precision machining are often required, increasing assembly complexity, time, and cost.
Oversized Component Dimensions: To compensate for a low coefficient of friction, engineers are frequently compelled to enlarge the size of connecting components or increase the number of bolts to transmit the required torque, resulting in bulky and heavy structures.
Elevated Costs and Material Consumption: The cumulative effect of the above issues ultimately drives up production costs (more materials, more complex processing, greater spatial footprint) and maintenance costs (more frequent inspections and replacements).
The Solution: DAOLER® High-Performance Friction Coating
In response to the multifaceted challenges posed by insufficient friction, DAOLER® Friction Coating offers an innovative and highly effective solution. By applying this specialized coating to contact surfaces—such as flange faces, shaft-hub interfaces, bolted joint faces, splines, clamping sleeves, and more—the coefficient of friction is significantly enhanced, fundamentally addressing the aforementioned pain points:
Eliminate Slippage and Enhance Torque Transmission Capacity: DAOLER® coating substantially increases the static coefficient of friction between mating surfaces—typically by 30% to 70% or even higher—ensuring efficient and reliable torque transfer, eliminating the risk of slippage, maximizing power transmission efficiency, and boosting equipment performance.
Effectively Suppress Fretting Wear and Corrosion: The coating forms a robust "barrier" at the contact interface, significantly reducing fretting displacement while exhibiting excellent wear resistance and corrosion protection. This drastically mitigates fretting-induced wear, material loss, and corrosion damage, extending the service life of both fasteners and base materials while reducing maintenance requirements.
Simplify Assembly Design and Reduce Complexity: A higher coefficient of friction means that the required axial clamping force (bolt preload) can be reduced for the same torque transmission, or that smaller-sized/fewer fasteners can be employed. This directly streamlines assembly design, minimizes the need for additional components, and lowers assembly difficulty and the risk of errors.
Enable Component Miniaturization and Lightweighting: Leveraging superior frictional performance, DAOLER® coating empowers engineers to design more compact and lightweight connecting components without the need to over-dimension for torque transmission. This contributes to overall equipment weight reduction and optimized spatial layouts.
Significantly Reduce Comprehensive Costs:
Material Costs: Smaller component sizes and fewer fasteners directly yield material savings.
Production Costs: Streamlined assembly processes reduce labor hours; component miniaturization may lower machining costs.
Maintenance Costs: Reduced unplanned downtime and component replacement due to slippage and fretting wear.
Lifecycle Costs: Enhanced equipment reliability and extended service life substantially lower the total cost of ownership.
