The article analyses general data on making choice of coatings and of surface hardening
methods of friction pairs. On the basis of common recommendations on choosing materi-
al surface layers we analyzed loading modes and coating selection for the friction pair
piston
—holes of block of cylinders for axial piston hydraulic machine; the recommenda-
tions take into consideration operating conditions of the friction pairs.
It is established
that it is better to use Teflon coating for the friction pair considered.
Keywords:
friction pair, Teflon coating, surface layer, loading mode.
