The Difference

Carbon–chromium carbide–chromium multilayer coatings were deposited by utilizing reactive high-power impulse magnetron sputtering with alternating various ratios of ethyne and argon mixtures under a constant total deposition pressure, target pulse frequency, pulse duty cycle, average chromium target power, and total deposition time. Two different alternating gas mixture periods were applied to obtain films with different numbers of layers and lamination thicknesses. The results show that the reduction in the modulation period effectively affects the elastic modulus and the subsequent ratio of hardness to elastic modulus (H/E) of the whole coating, which helps adapt the elastic strain in the coating. This improves the adhesion strength and wear resistance of coatings at room temperature. However, with the increase in wear test temperature, the difference between the wear behaviors of two types of coatings becomes inconspicuous. Both types of coatings lose the wear resistance due to the decomposition of hydrocarbon and the oxidation of the chromium content in the films.

High Power Diode Laser

To improve the wear resistance of brass substrate while retaining the electrical conductivity, laser cladding was applied to Cu-WC-Ni composite coating on brass using High Power Diode Laser. Microstructures, phase constitution and wear properties are investigated by means of scanning electronic microscopy with energy disperse spectroscopy and X-ray diffraction, as well as microhardness test and speed friction and wear test. The result shows that microhardness and wear resistance of clad coating were improved obviously compared with the brass substrate owing to the addition of WC ceramic phase, when the content of WC is 25%, the hardness of coating is 4 times of substrate, as well the cumulation mass loss is 1/19 of substrate. Electrical conductivity did not change as copper powder had high electrical conductivity.

Tin Coating

Titanium nitride (TiN) coating has been used in various application as it gives excellent performance in many aspects. It has been proven to prolong machining tool life since the mid-1960s. Industrial deposition processes of TiN, including magnetron sputtering, arc ion plating, and chemical vapor depositions, have their individual advantages and limitations. Due to the rising demands of the dry machining technique, the massive amount of heat generated from the friction of cutting tools against the surface of a work piece has become the main issue to overcome. Oxidation of TiN, which occurs around 400 °C, puts a limit on the applications of the coatings. Comparing TiN tool coatings deposited by arc evaporation, the novel high-power impulse magnetron sputtering (HiPIMS) technology provides smoother film surface, denser structure and subsequent corrosion resistance. Therefore, this research aims to investigate the wear behavior of TiN thin film deposited by HiPIMS at high temperature. The influences of the coating properties on the wear resistance of coatings at high temperature are also investigated. The results show that the HiPIMS technique enables a denser epitaxial-grown TiN coating with higher surface hardness and adhesion in contrast with TiN coating deposited using direct current (DC) magnetron sputtering techniques, which provides a higher wear resistance.

Alternated a-C/a-C:Cr coatings were made by DC magnetron sputtering from graphite and Cr target in an argon discharge. Mechanical and tribological properties were measured by indentation, scratch and pin-on-disc test. The critical scratch load of a-C/a-C:Cr multilayer coatings for total failure is approach 100 N. The friction coefficient remains within the range of 0.08-0.1 at loads between 10 and 40 N during a pin-on-disc wear test. The wear depth only reaches 0.6 μm after a one hour wear test. The greater compliance and fracture toughness of the a-C/a-C:Cr multilayer coatings allows greater strains or strain energy to be stored before coating failure, and hence significantly improves wear resistance

Sic Films

In this paper, SiC films were deposited on the surface of 316L stainless steel by magnetron sputtering with sintering SiC target to improve its wear resistance. The structure and morphologies of the SiC films were characterized by XRD and SEM. The impacts of sputtering way, deposition time, and substrate temperature on the deposition rate and mechanical properties of SiC films were further investigated by the performance parameters of hardness, elastic modulus, friction and wear properties, coating adhesion, etc. The results show that coating adhesion is higher when the films are deposited by mid-frequency magnetron sputtering than that of which by direct current sputtering; Hardness and elastic modulus of the films increased gradually with the deposition time changing from 1 to 5h or the substrate temperature changing from room temperature to 200°C; However, the friction coefficient initially decreases, but turns to increase with the deposition time prolonging or the substrate temperature rising. The wear resistance of the films is the best when deposition time is 2h and substrate temperature is 100°C.

The coatings deposited by physical vapor deposition (PVD) technique have found a wide industrial application as protective coatings for their attractive properties such as high hardness, good wear resistance and chemical stability. In order to explore the triboligical performances of CrSiN coatings, CrSiN coatings were prepared o the surface of 316 stainless steel by high power pulse magnetron sputtering (HPPMS) in this paper. Sliding wear tests of CrSiN coatings against Si3N4 ceramic balls and titanium balls have been carried out on a friction abrasion testing machine under reciprocating sliding conditions. nanoindentation and scratch tester, field emission scanning electron microscopy equipped with energy dispersive spectrometer (FESEM/EDS) and a X-ray diffractometer (XRD) was used to study the tribological behaviors of CrSiN coatings systematically. Results showed that CrSiN coatings exhibited good wear resistance, which can be attributed to the smoother and denser surface of CrSiN coatings resulted from much fewer macroparticles and pitting defects. The differences on wear debris removal behaviors and wear mechanism were caused by the different microstructure of CrSiN coatings.
