Influence of the Surface Layer Structure on the Interaction Character of Friction Pairs Formed by X155CrMol2-l, 41Gr4, and 35GrMnSi4 Steels with CuA19Fe4 Bronze

Abstract

А comparative analysis of tribotechnical characteristics of friction pairs of X155CrMo12 1,41Gr4, and 35GrMnSi4 steels with a counterbody of CuAl9Fe4 bronze, which were tested under conditions corresponding to operation of friction units of axial piston pumps, is carried out. Practical recommendations on the substitution of 35GrMnSi4 structural steel with the diffusion surface hardening for X155CrMo12 1high alloy steel when making the supporting and distributor disks of hydraulic pumps are formulated.
