| The tribological performance of metalwork steel tools is of vital importance in bothcold and hot working processes. One solution for improving metal tool life is the application ofcoatings. This paper investigates the differences in quantitative wear behavior and wear mechanismsbetween AlCrSiN-coated and bare steel K340 and five reference tool steels: X155CrVMo12-1,X37CrMoV5-1, X40CrMoV5-1, 40CrMnMo7 and 90MnCrV8. The investigated tool steels wereheat-treated, while K340 was subjected to thermochemical treatment and then coated with an AlCrSiNhard film (K340/AlCrSiN). The hardness, chemical composition, phase structure and microstructureof steels K340 and K340/AlCrSiN were examined. Tribological tests were conducted using theball-on-disc tester in compliance with the ASTM G99 standard. The tests were performed underdry unidirectional sliding conditions, using an Al2O3ball as a counterbody. The wear factor andcoefficient of friction were estimated and analyzed with respect to hardness and alloying compositionof the materials under study. Scanning electron microscopy (SEM) observations were made to identifythe sliding wear mechanisms of the analyzed tool steels and physical vapor deposition (PVD)- coatedK340 steel. In contrast to the harsh abrasive–adhesive wear mechanism observed for uncoatedtool steels, the abrasive wear dominates in case of the AlCrSiN. The deposited thin film effectivelyprevents the K340 substrate from harsh wear severe degradation. Moreover, thanks to the depositedcoating, the K340/AlCrSiN sample has a coefficient of friction (COF) of 0.529 and a wear factor ofK=5.68×10−7m3N−1m−1, while the COF of the reference tool steels ranges from 0.70 to 0.89and their wear factor ranges from1.68×10−5to3.67×10−5m3N−1m−1. The AlCrSiN depositionreduces the wear of the K340 steel and improves its sliding properties, which makes it a promisingmethod for prolonging the service life of metalwork tools. |
