The shaping of sliding surfaces of steel parts and friction pairs is a great potential for solving problems in the field of sliding pairs, such as: reduction of friction resistance, increase in lift, control of slotted flows, heat dissipation, and increasing the durability of friction pairs. The article presents tribological tests of a mapped sliding node based on selected vane pump components. The tests are carried out on the T-11 tribological tester (pin on disc) and are comparative in relation to standard elements. Surface changes in the tested friction nodes include the use of two additional machining processes, i.e., slide burnishing and texturing. The material for the samples is carbonitrided and heat-treated C22E steel, while the material for the counter-samples is E295 steel with a hardness of 160 HB (non-heat-treated). The use of additional processes in the form of burnishing and texturing on the sliding surfaces significantly reduces the friction coefficient by about 15% and reduces the resistance to movement for the tested combination. Tribological tests are carried out in two variants, i.e., with a constant sliding speed and variable load as well as with constant load and variable sliding speed about 50%. The authors conduct a number of studies, the results of which can be found in this work, in particular, for applications for the cooperation of parts of injection pumps.
