As a matter of fact, metal friction-reducing and self-repairing products are essentially different from traditional friction-reducing and energy-saving lubricant additives in terms of working principle. The metal friction-reducing and self-repairing technology is a kind of surface engineering technology that modifies the surface of mechanical friction pairs, rather than a lubrication engineering technology that improves lubricating or lubricant. Metal friction-reducing and self-repairing technology makes use of the lubricating system of the mechanic equipments, and injects metal friction-reducing and repairing agent that consists mainly of functional materials into the friction pairs of the machine. After absorption, lining, and filling up the micro dents and flaws of metal friction, the function materials interact mechanically, physically, and chemically with the surface materials of the friction pairs under the existing working conditions such as load, speed, and temperature. A smooth and hard metal-like modified ceramic layer is formed on the surface of the mechanical parts. The new surface has new metallographic and molecular structure, thus providing micro repair to the over-worn metal surface. The metal friction-reducing and self-repairing technology is highly effective in the maintenance of thermal power machines, such as gasoline engine and diesel engine. Take the automobile as an example, relevant experiments show that a taxi that adopts China's only proprietary MORUN metal friction-reducing and self-repairing technology, after 150,000 km, has longer lifespan for its parts and less maintenance times than used in normal condition; also, it can save up to 5 percent of fuel and it is remarkably cost-effective, saving around RMB 9,000 Yuan. To achieve all these, only RMB 1,000 Yuan are needed to invest on metal friction-reducing and self-repairing products. China has also attached great importance to the remanufacturing of auto parts. In recent years, several policies have been promulgated to promote the development of the remanufacturing industry. However, due to its short time of development and its uniqueness from ordinary auto parts remanufacturing, the metal friction-reducing and self-repairing technology has not yet to be listed as the country's remanufacturing pilot project. Accordingly, relevant companies face great capital pressure in their development, and can not enjoy preference treatment in such aspects as fund raising and tax reliefs, which results in its limited and slow spreading. Moreover, the limited application of the new technology and products has a lot to do with the consumers' limited knowledge and recognition of the technology and products. In developed countries, the remanufacturing industry that has now been industrialized had also been dull and insipid in the first decades of its development. Caterpillar, one of the world's largest engineering machinery manufacturers, has spent 40 years' efforts in promoting customers to try remanufacturing products that are the same as new products in quality and service and however are more cost-effective, so as to enable customers to recognize its products after a very long time. Therefore, experts believe that relevant government departments should provide policy and environment supports to promote the metal friction-reducing and self-repairing technology as soon as possible. It should be done is to deepen the understanding, start by enhancing planning and guidance, enhancing pilot project demonstration, and enhancing system construction, and accelerate in promoting the more extensive application of the metal friction-reducing and self-repairing technology in the automobile industry. Based on the China Association of Plant Engineering Mechanical Equipments Friction-reducing & Repair & Energy-saving Technology Center established last year, China Association of Plant Engineering should also establish a platform for the application of the metal friction-reducing and self-repairing technology in automobile industry and other equipment and engineering industries.
