Description

Technical field:

[0001] The invention relates to the field of development and application of new nanometer materials, in particular to the formulation, preparation and application method of a metal / ceramic nanocomposite self-repairing additive in different friction situations. Background technique:

[0002] Friction and wear are natural phenomena that commonly occur during the operation of mechanical equipment, and are also one of the three major causes of material and equipment damage and failure (wear, corrosion and fatigue fracture). According to statistics, 1 / 3 to 1 / 2 of the world's production energy is lost in friction and wear. The annual waste of resources caused by friction and wear in the United States is nearly 200 billion US dollars, and the annual loss caused by friction and wear in China reaches hundreds of billions of yuan. . Reducing wear and energy consumption and improving equipment utilization have always been one of the important research contents of coun...
