“…As a result, they enhance composite properties such as hardness, wear resistance, stable friction, corrosion resistance, and thermal properties. 17 Kumar et al 18 found that the mechanical and thermal properties of magnesium alloys were enhanced by using reinforcements such as oxide (Y 2 O 3 , CeO 2 , La 2 O 3 , ZnO, TiO, Al 2 O 3 ), carbide (SiC, B 4 C, TiC), or nitride (BN, TiN, AlN) materials. Tun et al 19 found that the composite's experimental density, hardness, and compression strength are increased by adding 0.7 vol.…”

Magnesium metal matrix composites for lightweight brake pad applications are developed in this study. The composites are fabricated by using the powder metallurgy process. The addition of 0.5 wt.% to 2 wt.% Y2O3 (Rare Earth Oxide) used as a reinforcement to the AZ31 Mg composite is investigated. Density, hardness, and tribometer tests are carried out according to the ASTM standards. The friction and wear test of magnesium composites is tested against the grey cast iron disc. FESEM analysis shows the microstructure and morphology of worn surfaces. The elemental mapping result depicts that the elements of Mg, Al, Zn, Y, and O are uniformly distributed in the composite. X-ray diffraction analysis shows the compounds of Y2O3, MgO, ZnO, and Al2O4 are present on the worn surface of AZ31 + 2 wt.% Y2O3 composite. The outcome of the experiment reveals that increasing the proportion of yttrium oxide increases the magnesium composite's density and decreases the porosity. AZ31 + 2 wt.% Y2O3 composite exhibits the highest hardness of 122HV, a stable coefficient of friction, and a lower wear rate compared to AZ31 + 0 wt.% Y2O3 composite.

“…However, some disadvantages are typical for laser cladding, including dissolution of WC particles in molten Ni-based matrix, resulting in hardness drop and increased coating porosity; sinking of high-density WC particles to the coating bottom forming, respectively, a nonhomogenous layer with the weakened top layer of the coating; crack formation due to thermal stress. The publications available in the field present various ways to solve mentioned problems, such as parameters optimization [18,22,23,25], substrate preheating [16][17][18]21,22,27], formation of gradient coatings [22], addition of rare-earth elements and other compounds [10,12,14,16,21,30], and vibration [12,29].…”

“…In the works [16,17,21,22,27], where authors used substrate preheating to a temperature from ~200 • C and up, the following best hardness results were reported: 760 HV at 59 wt.% WC in powder mixture [16], 1350 HV0.2 (for WC phase) [21], 740 HV0.2 at 10 wt.% WC [22], 1200 HV0.2 at 50 wt.% WC [27]. Zhou et al, in their work [18], obtained uniform ~1100 HV0.2 hardness using laser induction hybrid rapid cladding (LIHRC) method with substrate preheating to a temperature of ~1173 K. In the other works, where authors studied the effect of vibration [12,29] and addition of rare-earth element-containing oxides such as La 2 O 3 and CeO 2 [10,12,14], the following hardness values are given: ~500 HV0.2 at 60 wt.% WC [10]; 55 HRC/or 650 HV at 60 wt.% WC [12]; ~525 HV0.2 at ~50 wt.% WC [14]; ~1100 HV0.2 at 10 wt.% WC [29]. Recently, Zhao et al [30] proposed a novel hot-wire method for the deposition of Ni/WC composite coatings.…”

In the present study, pulsed laser post-processing was applied to improve the properties of the thermally sprayed NiCrCoFeCBSi/40 wt.% WC coatings. The powder mix was deposited onto a mild steel substrate by flame spray method and then the as-sprayed coatings were processed by Nd:YAG laser. The peak power density applied was between 4.00 × 106 and 5.71 × 106 W/cm2, and the laser operating speed ranged between 100 and 400 mm/min, providing processing in a melting mode. Scanning electron microscopy, energy dispersive spectroscopy, Knop hardness measurements, and “ball-on-disc” dry friction tests were applied to study the effect of the processing parameters on the geometry of laser pass and microstructure, hardness, and tribology of the processed layers. The results obtained revealed that pulsed laser processing provides a monolithic remelted coating layer with the microstructure of ultrafine, W-rich dendrites in Ni-based matrix, where size and distribution of W-rich dendrites periodically vary across remelted layer depth. The composition of W-rich dendrites can be attributed to a carbide of type (W, Cr, Ni, Fe)C. The cracks sensitivity of coatings was visibly reduced with the reduction of power density applied. The hardness of coatings was between ~1070 and ~1140 HK0.2 and correlated with microstructure size, being dependent on the processing parameters. The friction coefficient and wear rate of coatings during dry sliding were reduced by up to ~30% and up to ~2.4 times, respectively, after laser processing.
