Experimental Determination of Static and Dynamic Coefficients of Sliding Friction of Epilam-Coated Materials

摘要

The effect of the method for depositing epilam coatings on materials on the static and dynamic coefficients of sliding friction is experimentally studied. Experiments were carried out using the pin-on-plate arrangement under dry friction conditions at a constant velocity of sliding under pressures of 0.5-5 MPa. It has been found that, for a like friction pair made from the 14Kh17N2 steel, the deposition of epilam coatings on materials reduces the coefficients of friction, but the wear resistance of the coated materials changes only slightly because the epilam film has a molecular-layer thickness. Thermovacuum tests carried out at T = 350℃ under a pressure of 10~(-6) Torr have shown the loss of the antifriction properties of the materials covered with the 6SFK-180-05 epilam.
