Ball bearings are often seen in the transmission section of bicycles, while plain bearings can be found in the shaft of a ship. Bearings play a vital role in many drive and brake designs. They not only work well under high-speed engines and high-heat composite conditions, but also help materials meet the requirements of some extremely demanding working environments. Diamond-type coatings The emergence of the application is very good.
Scientists from the IWM Materials Performance Research Center in Freiburg, Germany, are actively developing new generations of bearings for the next generation. They have developed a special high-performance chemical coating for the bearings to provide a smooth surface in the bearing. Degree, reduce friction, so as to achieve the design requirements to extend the purpose of bearing use. These innovative coating products, mainly composed of diamond-type carbon (DLC), said Dr. Sven Meier, head of the research center, "The emergence of diamond-based coatings has given us a strong technology for future bearing design. Support. We are fully capable of designing new products that last longer than conventional bearings. The bearing technology and applications for this new coating are still under development, and we envisage that this product can be used without lubricants. The situation can be done well."
Of course, the surface treatment of diamond coatings on bearings also requires special coating processes, and IWM scientists have also completed the development of this process. Meier went on to say, “Our coating method can be used for surface treatment of complex geometric components such as bearing cages.” Engineers are currently optimizing this technology to achieve low-coat thickness performance. Application requirements, it is reported that IWM plans to control the coating thickness below 20 microns. “Our process ensures the coating service requirements for micron-sized coating structures. At this size, the coating can completely replace traditional lubricants or lubricants to minimize system friction. Special requirements can also create super smooth material surfaces."
Currently, researchers are further developing coating coating processes to ensure they meet the specific requirements of different sizes and shapes. IWM's goal is to reduce the high cost of existing bearing processing by optimizing the process, thereby reducing the cost of enterprise equipment procurement and equipment maintenance.
