PROGRESSES AND PROBLEMS IN NANO-TRIBOLOGY

The recent development in the four areas of nano-tribology is analysed . They are micro-and nano-friction and wear, micro- and nano-tribologi cal engineering. The research methods in nano-tribology and thin film lubrication in which five branches are included: equivalent viscusity and flowing characteristics of micro fluid, the transition between ord ered molecular film and disordered one, the essence of matrix influenc e on thin film lubrication, the lubrication mechanism of high polymer lubricants and the problem of superlubricity. Meanwhile, more than 35 problems are proposed which should be solved in the future.
