The tribological performance of metalwork steel tools is of vital importance in both cold and hot working processes. One solution for improving metal tool life is the application of coatings. This paper investigates the effect of CrAlSiN thin-film PVD-deposition on the tribological behaviour of tool steel K340. The sliding wear performance of the coated K340 steel is analysed in relation to both the uncoated K340 steel and a range of tool steels dedicated to hot- and cold-working, such as X155CrVMo12-1, X37CrMoV5-1, X40CrMoV5-1, 40CrMnMo7 and 90MnCrV8. The investigated tool steels were heat-treated, while K340 was subjected to thermochemical treatment and then coated with a CrAlSiN hard film (K340/CrAlSiN). The hardness, chemical composition, phase structure and microstructure of steels K340 and K340/CrAlSiN are examined. Tribological tests were conducted using the ball-on-disc tester in compliance with the ASTM G99 standard. The tests were performed under dry unidirectional sliding conditions, using an Al2O3 ball as a counterbody. The wear factor and coefficient of friction are estimated and analysed with respect to hardness and alloying composition of the materials under study. SEM observations are made to identify the sliding wear mechanisms of the analysed tool steels and PVD-coated K340 steel. In contrast to the harsh abrasive-adhesive wear mechanism observed for uncoated tool steels, the abrasive wear dominates in case of the AlCrSiN. The deposited thin film effectively prevents the K304 substrate from harsh wear severe degradation. Moreover, thanks to the deposited coating, the K304/CrAlSiN sample has a COF of 0.529 and a wear factor of K=5.68×10−7 m3 N−1 m−1, while the COF of the reference tool steels ranges from 0.702 to 0.885 and their wear factor ranges from 1.68×10−5 m3 N−1 m−1 to 3.67×10−5 m3 N−1 m−1. The CrAlSiN deposition reduces the wear of the K340 steel and improves its sliding properties, which makes it a promising method for prolonging the service life of metalwork tools.

Abstract. A horizontal mixer can realize the cutting and mixing of coarse and fine feeds and achieve the purpose of scientific feeding. Studying the wear resistance of the mixer blades can improve the service life of a horizontal mixer. The wear performance of blades made of three different materials (manganese steel, tool steel, and spring steel) was studied under laboratory conditions and working conditions. In laboratory conditions, the wear scar morphology and surface elements were analyzed by means of three-dimensional topography, scanning electron microscopy, and energy spectrum analysis. The results show that the friction coefficient, wear quality, and surface roughness of manganese steel blades had the lowest values of 0.49158, 0.0061 mg, and 4.341 µm in three groups of tests. In working conditions, the wear amount and surface roughness of the manganese steel blades in different zones of the mixer were the lowest. In addition, electron backscatter diffraction (EBSD) results showed that the grain size of the manganese steel blades was the smallest. Therefore, compared with the tool steel and spring steel blades, the manganese steel blades showed excellent wear resistance.HighlightsThe wear characteristics of horizontal mixer blades with different materials were studied.The wear characteristics of the blades were studied under laboratory and working conditions.The effect of grain on the wear performance of the blades was studied by electron backscatter diffraction.

TiN thin film has been produced on the surface of AISI D6 tool steel by using a titanium interlayer. In this work, the morphology, the microstructure and interface depth profile of TiN films deposited at two substrate temperatures (220 oC and 450 oC) in the coating process are presented and discussed. The AISI D6 tool steel substrates were coated with titanium thin film as the underlayer and with TiN thin film as the top layer. They were deposited by conventional cathodic arc process. The surfaces of TiN films were observed by scanning electron microscopy (SEM). The microstructure of these samples was analysed by X-ray diffractometry (XRD). The influence of the substrate temperature on the TiN film-Ti film-AISI D6 interface region were investigated by energy dispersive spectrometry (EDS) and its cross section were observed using backscattered electron image (BEI). The results showed that TiN films deposited at 220 oC formed a film of strongly (111) preferred orientation, while in 450 oC formed a film of (111) and (220) preferred orientation. The thickness of the TiN films increased with increasing substrate temperature. The results show that the interface region of the TiN film-Ti film-AISI D6 substrate system was significantly improved when higher substrate temperature during deposition is used.

In this study, tool steel substrates were plasma-nitrocarburised at different processing parameters and afterwards tribologically tested under non-lubricated sliding conditions. It was observed that the micromechanical properties of the compound layer (thickness, hardness, roughness, surface topography) strongly affect the tribological behaviour of the nitrocarburised surface and can be tailored through the adjustment of the nitrocarburising parameters so that very favourable wear and friction behaviours can be achieved.
