Nano composite coatings of wear resistance and antifriction were fabricated by electrical brushing containing nano-particles Al_2O_3 and PTFE.

The antifriction and antiwear mechanisms of different low molecular weight liquid crystal were illustrated.

The effect of four types of repairing accelerants on friction-reducing and self-repairing of TiO_2/SiO_2 nano-additive were studied in Kunlun vehicle gear lubricant,the mechanism was analyzed.

Several new-type of high temperature resin matrix antifriction-reducing composites and nano-solid lubricants at home and abroad in recent years was surveged.

Their friction-reducing and antiwear properties under different experimental conditions were introduced.

Preparation of Scuffing Resistance Anti-friction Material for Bolt at High Temperature;

Bearing capacity and anti-friction behavior of ultrasonic vibration bearing;

Anti-friction and Wear Resistance Mechanism of FeS Layer;

According to the condition of material failure and mechanical equipment breakdown, a kind of tribo-treatment lubricant with excellent antiwear property and friction reduction property was developed based on tribochemical treatment technique.

The load-carrying capacity, friction reduction and antiwear properties of borate containing the R2NC ( =S ) S-group, added in liquid paraffin under boundary lubrication conditions were evaluated using four-ball machine and HQ -1 ring-on -block tribotester.

The result shows that the lubricant contained "ZY-1"additive represents a function of self-covering layer on the surface of the friction,and that the function in view of friction reduction is superior to that of Shell lubricant.

The comparative study of properties between Pb-Sn coatings and some conventional aeronautical lubricating and reducing friction coatings had been performed in this paper.

Then, improving measures about instrument pipe, air-power coming out of earth, reducing friction were emphasized.
