Conclusions

  1. 1.

    A study was made of the antifriction properties (coefficients of friction and rates of wear) of W, Mo, Nb, and Ta disulfides and diselenides and of the complex selenides and sulfides Mo0.2Ta0.8Se2,Mo0.1 Ta0.9S2, and Mo0.25Ta8in0.75S2 in air and in a vacuum of 10−6 mm Hg.

     
  2. 2.

    It was established that the properties are directly related to the crystal structure of the compounds investigated.

     
  3. 3.

    It is shown that, to exhibit good antifriction characteristics, disulfides and diselenides should be of stoichiometric composition and should have a lamellar structure with a trigonal-prismatic coordination of the sulfur and selenium atoms.
