“…e rate of wear increases drastically when the mean free path between the WC particles exceeds 114 μm. is is because a greater distance between WC particles produces a significant fraction of the metallic Ni matrix on the surface of the wear track in direct contact with abrasive sand particles [26][27][28].…”

The tribological behavior of Ni-based WC-Co coatings is analyzed. The coatings were deposited on gray cast iron substrates in a spray and fuse process using SuperJet Eutalloy deposition equipment, varying the oxygen flow conditions in the flame. The crystallographic structure of the coatings was characterized via the X-ray diffraction (XRD) technique. The microhardness was measured on the surface and in cross sections of the coatings by means of a Knoop microhardness tester. The topography and the morphological characteristics of the coatings and the tribo-surfaces were examined using scanning electron microscopy (SEM) and confocal microscopy, while the chemical composition was measured by means of energy-dispersive X-ray spectroscopy (EDS). The tribological behavior of the coatings was examined via a cohesion-adhesion scratch test, using cross sections of the coatings. Furthermore, two wear tests were carried out, using the pin-on-disk method under ASTM G99 standard and an ASTM standard G65 sand/rubber wheel abrasion wear test. The wear of the coatings showed a close relationship to the porosity in the metal matrix; since then, in the abrasive wear test, a high porosity is related with lower hardness in the coatings; likewise, a low hardness is related with a high wear.

“…Further, it was reported that WC and Co particles exhibited higher bonding strength and lead to better wear resistance. 8 , 32 The WC-based particles have a strong wetting capacity with Ni particles. 10 , 11 The development of functionally graded metal–matrix composite clads is a very challenging task as it involves the interaction of microwave with metallic particles.…”

“…[5][6][7] These hard particles are primarily mixed with metallic binders to form metal-matrix composite coating/cladding, which is associated with excellent mechanical and wear resistance characteristics. 8 However, in the case of single-layer cladding, the formation of a sharp interface usually occurs between cladding material and substrate. This sharp interface presence is due to the difference in the thermal expansion coefficient of substrate and clad materials resulting in crack propagation and set up of build-up stresses at the common interface.…”

Functionally graded materials are inhomogeneous materials with the gradual change in properties with position. In this research work, functionally graded clad layers of Ni-WC8Co-based materials with varying compositions of WC8Co from 0 to 30 wt% were processed using a cost-effective and energy-efficient microwave hybrid heating technique. Single-layer clads of compositions corresponding to different functionally graded clad layers were also developed through microwave heating for comparing different properties. The processed functionally graded clads were characterized through microstructural analysis (scanning electron microscopy/energy-dispersive X-ray spectroscopy) and Vicker’s microhardness quantification. Microstructure results showed the functionally graded clad of approximately 2 mm thickness was free from any visible pores and interfacial cracks. Microwave heating resulted in the formation of hard phases in the functionally graded clad layers, and these layers exhibited significantly higher microhardness values. Further, the tribological performance of developed functionally graded clad was examined under dry sliding conditions using pin-on-disk-type tribometer. The influence of varying sliding velocities and sliding distances on the wear characteristics of microwave-processed functionally graded clads were investigated. It was observed that microwave-processed functionally graded clad exhibited approximately 95%, and 29% higher wear resistance than the SS-304 substrate and Ni + 30%WC8Co-based single-layer clad respectively owing to its better mechanical properties.

“…At present, WC based composite coatings have been widely investigated [15][16][17][18][19]. According to the bonding phase, WC based composited coatings are mainly divided into WC-Co [15,[20][21][22][23], WC-Ni [24][25][26] and WC-CoCr [1,[27][28][29][30][31]. Lalit et al [32] evaluated the effects of the different WC grain sizes on slurry erosion behavior of WC-CoCr cermet coatings, the test result was observed that WC-CoCr cermet coatings deposited with fine WC grain shows the greater erosion resistance as compared with conventional cermet coatings, and the damage caused by erosion started with chipping, cracking and pullout of WC grain from CoCr binder phase.…”

The present study investigated the erosion wear behavior of WC-Ni and WC-Cr 3 C 2 -Ni cermet coatings deposited by high velocity oxy-fuel (HVOF) spray process on the substrate of 1Cr18Ni9Ti stainless steel. Microstructures and morphologies of the coatings were examined using SEM images, and x-ray diffractometer was used to analyze the phase composition of the powder and the coatings. The erosion test was carried out using home-made jet rig. In order to better fit the research background of this study, the erodent used for erosion was taken from the Yellow River, China. The coating is well combined with the substrate; and WC-Cr 3 C 2 -Ni coating consists of WC, Cr 3 C 2 and Ni phases, WC-Ni coating consists of WC, W 2 C and Ni phases. Some mechanical properties of the two coatings were compared, WC-Cr 3 C 2 -Ni coatings have higher hardness to be compared with WC-Ni ones due to a lower binder content; and the elasticity modulus and nano-hardness values of the WC-Cr 3 C 2 -Ni coating are higher than that of the WC-Ni coating. The relationship between the wear performance of the coatings and impingement angle was obtained; and the erosion resistance of the coatings was analyzed. It was observed that WC-Cr 3 C 2 -Ni cermet coating exhibits higher erosion resistance under all testing conditions as compared with the WC-Ni cermet coating and 1Cr18Ni9Ti stainless steel. The results show that the erosion mechanism at low angle is mainly cutting, while erosion pits dominate at high angle for the coatings, moreover, plastic deformation could be observed in the case of the binder depletion and cracking found place. and the erosion mechanisms of the 1Cr18Ni9Ti stainless steel are mainly cutting and plastic deformation at low angle and high angle, respectively.
