The influence of the technology of piston rings’ strengthening by multilayer ion-plasma TiN/CrN coating is studied. The peculiarities of their wear at the sliding speed of 1.3 m/s, which contributes to the maximum changes, are revealed. As shown, under these test conditions, as a result of hardening, wear resistance is increased by 15 times. The method of optical-mathematical analysis reveals the features of the friction surface structuring, which have the form of transverse and longitudinal bands. Wide transverse bands (∼ 20 μm) are typical for the friction zone between rings and TiN/CrN coating and they determine a high degree of wear resistance.
Key words: piston rings, ion-plasma coating, optical-mathematical analysis, structuring, friction tests.
