The novel technology of multilayer coating deposition combining electric-spark alloying (ESA), pulsed arc evaporation (PAE), and magnetron sputtering (MS) in one vacuum process is presented. Layers can be deposited using a single electrode material at operating pressures from 0,1 Pa to atmospheric pressure. The lower ESA layer provides increased substrate toughness, perfect adhesion and a relatively high (up to 100 μm) coating thickness. The upper PAE or MS layer up to 10 μm in thickness provides high mechanical and tribological characteristics. The technology of double-layer PAE–ESA and MS–ESA coating deposition was tested on substrates made of structural and tool steels, titanium alloys using electrodes of cemented carbides (WC–Co, TiCNiAl) and carbon (low-porous graphite).

Cathodic Arc

In this paper, TiN, ZrN, TixZr1-xN, Ti1-xAlxN coatings were obtained by cathodic arc evaporation at optimal technological parameters. The corrosion properties of these coatings were investigated in 5% NaOH. The coating ZrN deposited by cathodic arc evaporation slows down the corrosion in the 5% NaOH by over 3,000 times, and the passive current – by 2,000 times. The TixZr1-xN coating has the best physico-mechanical properties: microhardness Н = 36 GPa, Young’s modulus Е = 312 GPa, elastic recovery We = 78 %, resistance to elastic failure strain H/E = 0.12, and resistance to plastic strain H3/E2 = 1.31 GPa. The Ti1-xAlxN coating has the best wear properties: friction coefficient 0.09, counterbody wear intensity by volume 0.43•10-8 mm3/Nm, coating wear intensity by volume 0.05•10-4 mm3/Nm and by mass•0.03•10-5 mg/Nm. Multilayer coating TiN-TixZr1-xN-Ti1-xAlxN-ZrN (ZrN-top layer) has a complex of high physico-mechanical and wear properties in 5% NaOH.

This paper is a continuation of our previous work. The article presents an investigation of the influence of coating deposition parameters, in particular a variation with 50% of both cathodic arc current and bias voltage, on the mechanical and tribological properties of TiCN coatings deposited by the cathodic arc evaporation of metals at a constant gas ratio. The thicknesses of the coatings are measured by the Calotest method using a 30-mm hard steel ball. The determined values are in the range of 734 – 1534 nm. Surface morphology and chemical composition are estimated by a Scanning Electron Microscope (SEM) and an Energy Dispersive Spectrometer (EDS) of SEM. The determined values of nanohardness are in the range of 10 - 23 GPa and adhesion values are in the range of 28 - 70 N. Tribology of the TiCN coatings is investigated with three different load forces (3N, 5N and 8N) by the CETR UMI Multi-Specimen Test System from Bruker with an Si3N4 ball counter-body. The friction coefficient is measured in the range of 0.19 - 0.23. Coating wear and wear of the counter-body are calculated, according to the standard EN1071-13:2010, wherein the values of the latter are in the range of (2.5 - 30) x 10-6 mm3.
