“…As a solid solution, the (Ti,Cr)C is expected to possess the main advantages of TiC with higher oxidation resistance owing to the formation of Cr2O3 [11]. In order to improve the fracture toughness and cohesion of coatings, the metal or alloy powder are introduced as the binder into (Ti,Cr)C-based composite powders [12][13][14][15][16][17]. Among metal binders, Ni is an attractive component for cermet coatings due to its high toughness and oxidation resistance [18].…”

Thermally sprayed cermet coatings are widely used in many engineering applications to protect against wear and corrosion. In this study, three kinds of (Ti,Cr)C-based powders with 18, 25, 33 wt.% content of Ni binder were deposited onto stainless steel substrates by plasma spraying technique. The microstructure and dry sliding wear resistance of the (Ti,Cr)C-Ni coatings were investigated. The (Ti,Cr)C-Ni coatings have a heterogeneous structure composed of (Ti,Cr)C particles and Ni binder. Fracture and partial dissolution of the (Ti,Cr)C particles were found to occur during the plasma spray process. Among all the tested coatings, (Ti,Cr)C-33wt.%Ni coating exhibits lower wear rates and friction coefficients under all conditions. Worn surfaces of the coatings were analyzed using SEM to investigate the wear mechanism. With the increase in Ni content from 18 up to 33wt.%Ni wear mechanism of the (Ti,Cr)C-Ni coatings changes from abrasive to tribo-oxidation.

“…Currently, many technologies are used in industry for the deposition of composite coatings to protect machine parts against wear [14][15][16][17]. Surface modification technologies make possible to form coatings with tungsten carbide [18], aluminum oxide [19,20], chromium [21] etc.…”

The paper presents an analysis of technologies for improving the quality parameters of the surface layers of parts, which were carried out by the method of electrospark alloying (ESA) and by additional saturation of surfaces with alloying elements from special process media (STM). The technology of sulfocementation was considered. Metallographic and hardness tests after sulfocementation by ESA showed that the treated surface consists of layers: "soft", hardened and base metal. As the discharge energy increases, the thickness, microhardness and integrity of the coating increase. The presence of sulfur in STM promotes the sulfidation process. It is shown that sulfur accumulates on the surface of the metal at a depth of up to 30 μm. This zone is characterized by reduced microhardness. A strengthened layer is formed under this layer, it has an increased carbon content and high microhardness.

“…Several attempts have been made to produce the (Ti,Cr)C-based metal-ceramic materials and protective coatings [9][10][11][12][13]. It was shown, that the (Ti,Cr)C-FeCr plasma-sprayed coatings demonstrate a high wear resistance under fretting conditions [9].…”

“…Besides, the (Ti,Cr)C-based cermet coating has erosion resistance, comparable to that of the tungsten carbide cermet coating, but with a much higher thermal shock resistance [10]. According to the study [11] the (Ti,Cr)C-Ni system can be successfully used to develop metal-ceramic composites, as it is characterized by good wetting (θ = 8 deg). Adding the (Ti,Cr)C particles is effective way to improve wear resistance of the NiCrBSiC alloy-based plasma-sprayed coatings under dry sliding conditions [12].…”

Adding the (Ti,Cr)C particles is effective way to improve wear resistance of the NiCrBSiC alloy-based plasma-sprayed coatings under dry sliding conditions [12]. The nickel additions were found to substantially decrease the oxidation rate of the (Ti,Cr)C-based composites and shift the thermal effects toward much higher temperatures [13].…”

This study reports the influence of Ni content on the structure and wear resistance of (Ti, Cr)C-based coatings. The (Ti,Cr)C-based composite powders, cladded with 18, 25 and 33 wt.% Ni were used to deposite coatings on stainless steel substrate by detonation spraying technique. The thickness of the coatings reaches 350-500 μm, the porosity is about 2%. The (Ti,Cr)C-Ni coatings have a dense lamellar microstructure with uniform distribution of refractory particles and metal binder. The wear behavior of the coatings against steel ring were investigated by dry sliding wear tests. Depending on the Ni content the sliding wear loss of the (Ti,Cr)C-based coatings was 1,2-2 times less than that of (Ti,Cr)C detonation-sprayed coating. The investigation of worn surfaces revealed that the wear mechanism of the (Ti,Cr)C-based coatings with Ni content increase changes from abrasive to oxidative.
