Frictional coeffident

Diamond has been well-known for long for its outstanding mechanical properties like great hardness and low frictional coeffident Therefore, it was self-suggesting to examine the respective characteristics of diamond films as well. Actually the results are found to vary depending on the morphology of the film and, for polycrystalline materials, on the particle size. 

An investigation of the boundary friction of paraffin on glass in the presence of a stearic add soap intermediate layer is also very important [393]. This showed that with increase in the number of mono-layers applied, the true friction coeffident does not depend on where in the lubricating layer the shp plane is. 

On the contrary, for the oleftnic lubricant, the friction coefficient increased with the increasing number of redprocating cydes because of the weaker cohesive interactions. The ammonium salt polar group can be introduced to the commercial PFPE, and the frictional coeffident is independent of the molecular structure of the PFPE backbone polymer and of the thinner dip)-coating, which makes practical use convenient without any environmental problems. 

Nylcm 66 has a low coeffident of friction. In the presence of water this value is lowered bdow that of graphite. The coeffident of friction in the presence of liquid fmatfUa Is extrmdy low (0.13). Nylon 66 has excellott reststanoe to abrasion.
