Coatings reinforced with higher weight percentages of rGO had extremely low wear rates and offered a low coefficient of friction, with unpulled rGO acting as protective layers. However, it was also observed that the wear of coatings with 0.5 wt% and 1.0 wt% rGO addition was mainly due to the delimitation and subsequent pulverization at 1.5 kgf load and 0.17 m/s sliding speed.

This was achieved by combining dry powders of DCPD and calcium carbonate (CaCO₃) [Ca/P ratio: 1.5] with varied quantities of 10%, 20%, 30%, and 40% of sodium chloride (NaCl) powders to obtain mixtures composed of weight percentages (wt%) ratios of 90:10, 80:20, 70:30, and 60:40, respectively. Post-sintering, the porous β-TCP granules fabricated were soaked in an acidic calcium phosphate solution for 30 min to coat the surfaces with DCPD crystals formation via a dissolution-precipitation reaction. Subsequently, the specimens were examined with scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared (FTIR). The morphological observations demonstrated that increasing NaCl powder up to 40% with a mixture of CaCO₃ and DCPD enhanced the β-TCP granules' pore size. Furthermore, The formation of DCPD on and inside the porous β-TCP granules has been accelerated due to the presence of large pores.

The major XRD peaks of the DCPD and β-TCP phases with 2.8, 4.9, and 6.91 μm pores were also slightly shifted to the right, while granules with 7.53 μm pores demonstrated DCPD and β-TCP peaks aligned with pure β-TCP and DCPD phases.

The molten slags mainly penetrated the MO substrates through pores, cracks, and grain boundaries, forming silicate, and vanadate phases at the slag–MO interface. In particular, the V–containing slag demonstrated stronger susceptibility to corrode the MO substrate due to the capacity of V to form low–melting point phases with MgO.

In the initial design, the holes were placed on the honeycomb sandwich structure’s upper and lower face-sheets. In the second design, the holes were positioned in the direction of the sample thickness, in the lateral walls. The moment of inertia values for the honeycomb structures were calculated with the help of experimental elastic modulus results, and true bending strength was determined according to these results. Nominal strength values were found using the common three-point bending formula. The true bending strength value of Al₂O₃ with lateral holes was 73% higher than Al₂O₃ with holes on face-sheets, while the nominal bending strength was 79% higher. Al₂O₃ samples with holes on face-sheets exhibited a significantly higher failure index compared with both the bulk samples and the Al₂O₃ samples with lateral holes. The holes on the face-sheets reduced the cross-sectional area of the tensile surface and contributed to an increase in stresses due to the stress concentration effect.
