“…For HVOFS MMC coatings, Ni-based self-fluxing alloys (NiCrSiB) were found to be an optimal choice as the matrix material [ 5 ]. In this case, tungsten carbide-cobalt hardmetals (WC-Co) are commonly used as reinforcement [ 6 ]. However, WC-Co is prone to loss of carbon with the formation of brittle W 2 C phase during the spraying process [ 7 ] that worsens the performance of sprayed coatings.…”

In the current article, high-velocity oxy-fuel (HVOF) sprayed composite powder TiC-NiMo and Cr 3 C 2 -Ni cermet particles reinforced self-fluxing alloy matrix (FeCrSiB) coatings were studied. The actual content of the reinforcement in the sprayed coatings was smaller in comparison with the feedstock powders. Cermet particles were deformed at the impact with the substrate, deformation was more remarkable in the case of the TiC-NiMo particles. Sprayed coatings exhibited a structure with a number of defects, like voids and cracks, whereas the latter were more pronounced in reinforced coatings. Despite the bigger number of defects, cermet particles reinforced coatings had up to 1.2 times higher surface hardness than the unreinforced coating. TiC-NiMo particles reinforced coating demonstrated 1.8 times higher sliding wear resistance than the unreinforced coating. Cr 3 C 2 -Ni particles reinforced coating showed 1.3-2.8 times higher sliding wear resistance in comparison with the unreinforced coating, depending on the series of tests. Addition of cermet particles allowed to increase the resistance of the FeCrSiB matrix to deformation and scuffing.

“…These coatings are made onto a substrate through various coating techniques such as Chemical Vapour Deposition (CVD), Thermal Spraying, Physical Vapour Deposition (PVD) RESEARCH and Sputtering through which the mechanical properties and wear resistance can be improved and friction can be reduced [6]. From previous literatures, it was concluded that these coatings (WC-Co) were widely used due to their superior combination of properties such as high hardness, toughness and wear resistance [7][8][9][10]. It was also confirmed that WC-Co coatings applied on bearings had improved the wear and corrosion resistance and also improved the bearing performance under poor lubricating conditions.…”

Pure copper was coated with Tungsten Carbide-Cobalt (WC12%-Co) using Detonation-Gun technique. A coating thickness of 541 µm was obtained and the hardness of WC-Co coated copper surface was 5.2 times greater than the hardness of uncoated surface. The wear properties of coated copper were investigated using pin-on-disc tribometer, where the WC-Co coated copper exhibited higher wear resistance than uncoated copper. Dry sliding wear properties of WC-Co was analysed using Response Surface Methodology by considering the parameters load (10, 20, 30 N), sliding velocity (0.75, 1.5, 2.25 ms-1 ) and sliding distance (750, 1250, 1750 m). The results indicated an increase in the wear rate with increasing load and velocity, whereas the increase in the distance showed minimal increase in wear rate. The worn surfaces were analysed using Scanning Electron Microscopy to understand the wear mechanism. The result from the presented experiment may find its application in clutch selector fork of automobile transmission and bearings.

“…The working surfaces of parts are mainly hardened with the use of three groups of materials, i.e., self-fluxing alloys based on iron, nickel, and cobalt [12 -14]. The nickel-and cobalt-base alloys possess good wettability, deoxidizing and flux-forming capacities [12], high physical and mechanical characteristics [13,14] and a high resistance to wear, oxida tion and high-temperature corrosion [15,16].…”

Some parameters of laser surfacing of self-fluxing nickel alloy PG-12N-01 are considered. Different struc tures containing a low-melting y-Ni -Ni3B eutectic and a y-Ni -Cr3C2 eutectic that crystallizes at a higher temperature and forms the strength skeleton of the coating may form depending on the rate of the surfacing. The effect of the rate of the surfacing on the wear resistance of the coating and on the coefficients of dry fric tion are determined.
