The hardness, strength, and tribotechnical characteristics of a hard-lubricating composite material based on modified K-153A epoxy resin filled with WSe2 particles in an amount of up to 70 wt % are investigated. The compound modified by ~20 wt % WSe2 has the best set of properties: the hardness is ≈79 HRC (on scale L), the compressive strength is ≈155 MPa, the compressive yield strength is ≈90 MPa, the wear intensity under dry sliding friction is ≈0.18 × 10–8 mm3/(N m), and the coefficient of friction is ≈0.2. The material can be recommended for rotaprint application onto the flanges of rolling stock wheels. [ABSTRACT FROM AUTHOR] |
