“…Higher the peak intensity of W and W 2 C phases, higher is the decomposition of WC phase, which implies that C-WC cladding exposes to higher decomposition than N-WC cladding. However, both the claddings reported the absence of Co 3 W 3 C, Co 6 W 6 C and other unwanted phases [33].…”

The present research examines the wear performance and cost of developing the micrometric and nano-metric WC-10Co-4Cr GTA claddings. The claddings were developed at optimized parametric conditions using a fully automatic GTA welding machine. The microstructure, elemental compositions and phases present in the deposited claddings were characterized by using FE-SEM, EDS and XRD, respectively. Micro-hardness of the micrometric and nano-metric claddings were evaluated with the help of a Vickers hardness tester. A pin-on-disc tribometer was used for conducting the abrasive wear test. The experimental results revealed that the abrasive wear in nano-metric cladding reduces by 30.72 % compared to micrometric cladding. The average microhardness of nano-metric cladding has improved by 25.51 % than micrometric cladding. Microstructural examination of worn-out claddings shows that the material was removed from the claddings due to the eruption of CoCr binder matrix along with the pull-out of WC grains, caused by the sliding motion of SiC particles. However, the cost of fabricating nano-metric cladding per unit area (Rs 0.163/mm2) was higher than the micrometric cladding (Rs 0.107/mm2) owing to the higher material cost of nano-WC-10Co-4Cr powder.

“…The use of GTA cladding process was explored to study the wear performance of WC-CoCr material. The results showed the improved abrasive wear resistance along with high hardness [20,21]. To further improve the properties and performance of WC-CoCr material, grain size of WC has been reduced to nanometres [22,23].…”

In this study, Mo-based composite coatings with 1 wt.% of rare earth oxide (Y2O3) contents were successfully manufactured on AISI SS304 (stainless steel) by Argon shielded Arc (ASA) cladding method. The effect of Y2O3 on phase composition, microstructure, mechanical and tribological properties of Mo-based coatings were investigated by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM) with energy dispersive X-ray spectrometer (EDS), Micro-Vickers hardness apparatus and Pin-on-disc type wear tester. The result demonstrates that the upper surface of composite coating with and without addition of Y2O3 were mainly comprised of TiB2, Ni3Ti, Fe3Mo, MoNi4, NiTi, Mo2B, Y2TiO7, and MoNi4 appeared. The constituent phase components in the coated layer were found to be beneficial for the enhancement of the microhardness and wear resistance. The maximum value of average micro-hardness and wear resistance was observed in samples having 1 wt.% of Y2O3 as a precursor. The average microhardness of Mo-based coatings with Y2O3 addition was in the range of 1599 to 2170.4 HV0.1 and wear resistance increases from 1.41 to 6.36× 10-8 g/N-m. The pronounced effect of Y2O3 addition on microhardness and wear resistance of coatings were consistent with the calculation results of applied multivariate statistical analysis. Thus, it can be concluded that addition of Y2O3 is effective and achievable way to solidate hardness and wear resistance of Mo-based coatings.

“…In view of the problems of low surface hardness, poor wear resistance, and corrosion resistance of steel materials, surface strengthening technology is widely used to prepare surface carbide reinforced composite layers to prolong the service life of the workpieces [1,2]. The current methods for producing surface carbide reinforcement layers include spraying [3,4], surfacing [5,6], vapor deposition [7][8][9], laser cladding [10,11], and vacuum dipping infiltration casting [12,13]. However, all the above methods still possess structural or functional shortcomings such as difficulty in obtaining high-volume fraction ceramic reinforced dense layers, poor interfacial bonding between the reinforced layer and the matrix, laboriousness of the process, long cycle, and high cost.…”

In this study, an NbC-Fe composite layer is in-situ prepared on the surface of GCr15 bearing steel. The formation mechanism of the composite layer was investigated in terms of thermodynamics, dynamics, and crystal structure transformation processes during the in-situ reaction. According to computational thermodynamics, the reaction at 1150-1200℃ allows NbC, Fe3C, Cr3C2, Cr7C3, and Cr23C6 phases to spontaneously react and stabilize in the Fe-C-Nb-CR system. The functional relationship between the growth thickness, time, and temperature of the NbC-Fe composite layer was obtained experimentally and via computational dynamics. Particularly, the growth activation energy, Q, of the NbC-Fe composite layer was calculated to be 367.06 kJ/mol. The combination of computational thermodynamic/kinetic research and experimental observation of crystal transformation data revealed that the formation mechanism of NbC in the NbC-Fe layer on the surface of GCr15 caused the C atoms in the bearing steel diffuse into the Nb plate and occupy the octahedral gap of the Nb unit cell to form NbC. In the formation mechanism of the NbC-Fe composite layer, C and Fe atoms partially migrated from the pearlite and diffused towards the direction of the Nb plate to form the NbC-Fe composite layer.
