Description

technical field [0001] The invention belongs to the field of composite materials, and relates to an aluminum-coated AlN nanofiber reinforced Al-Fe-based nanoporous alloy material and a preparation method thereof. Background technique [0002] Belt conveyors are widely used in various fields such as industrial production, rail transit, and material distribution, and are important transportation equipment for transporting items. The pulley is the core component of the belt conveyor. In practical applications, the pulley is required to be reliable, energy-saving, and have a long service life during transmission. The existing drum is made of stainless steel, which has good corrosion resistance, but its disadvantages are heavy weight, high energy consumption during operation, and high noise. Especially when it is applied to fields such as high-speed transmission industrial production, the cost is high and the impact on the environment is great. Therefore, how to increase the se...
