“…The measurement of surface roughness and porosity of coated and uncoated samples was carried out by employing a 3D laser scanning microscope [27][28][29][30] . Additionally, the hardness of the interface between the coated and uncoated samples was assessed using a Vickers micro hardness tester.…”

A modern machine parts such as gas turbine blades and vanes are impacted by high temperature and high speed solid dust particles. As a result may leads to disastrous failure. In order to increase the performance multilayered (WC-SiC-Cr3C2) carbide coating was developed on AISI 304 steel using HVOF process. Erosion test as per ASTM G 76 standard were conducted at differently impingement angle (90 0 ,75 0 ,60 0 ,45 0 and 30 0 ) at room temperature. Micro structural, morphological and element analysis probed using SEM and EDAX. The changes in the resistance to erosion are due to high hardness and less porosity of the developed coating. The analysis showed a well-adhered and dense layer with a uniform distribution and presence of carbides and ability to withstand the erosive effects of solid dust particles.

“…Composites have several uses in the automotive and marine sectors. Excellent corrosion resistance, as well as high stiffness-to-weight ratios, all contribute to the robustness and creep resistance of these applications [2][3][4][5] . Asia's developing countries are currently dealing with problems including growing urbanisation and the need for more secure and opulent travel in order to maintain a normal way of living by introducing composite materials 6) .…”

Fiber Reinforced Polymer composites materials are replacing traditional composite materials practical applications for some years due to characteristics such as high durability, resistance to corrosion, flexural strength, in addition to outstanding mechanical properties specific towards the substance. Thus, the objective of current work is to investigate the manufacturing of multi natural fibre reinforced polymer composites, as well as study their mechanical characteristics, and set side by side them to those produced with a single natural fibre reinforced composite. Fiber-reinforced polymer composite's density and hardness were determined to be within acceptable levels by conducting flexural and tensile strength tests on the composites. The ASTM standards samples method were utilised to produce the specimens of composite with varying fibre weight percentages using the hand-lay-up technique. Carbon fiber reinforced plastics (CFRP) composite material has a maximum tensile strength of 240 MPa and can sustain that strength. The maximal impact strength of the CFRP composite is 69.21 KJ/m2. The performance of Fiber-Reinforced Polymer composites is found promising.

“…For biomedical purposes, a Co-Cr alloy material was coated with different contents of HA-ZrO 2 mixtures, using the flame spraying method. The effect of HA/ZrO 2 particles on the corrosion resistance of the resulting coatings was evaluated, and the reported results highlighted a significant improvement in the corrosion behavior of the bio-ceramic-reinforced coatings [ 42 ]. Moreover, ZrO 2 shows impressive toughness, strength, and fracture strength; low elasticity module and fatigue; and wear resistance [ 30 , 43 ].…”

Without proper post-processing (often using flame, furnace, laser remelting, and induction) or reinforcements’ addition, Ni-based flame-sprayed coatings generally manifest moderate adhesion to the substrate, high porosity, unmelted particles, undesirable oxides, or weak wear resistance and mechanical properties. The current research aimed to investigate the addition of ZrO2 as reinforcement to the self-fluxing alloy coatings. Mechanically mixed NiCrBSi-ZrO2 powders were thermally sprayed onto an industrially relevant high-grade steel. After thermal spraying, the samples were differently post-processed with a flame gun and with a vacuum furnace, respectively. Scanning electron microscopy showed a porosity reduction for the vacuum-heat-treated samples compared to that of the flame-post-processed ones. X-ray diffraction measurements showed differences in the main peaks of the patterns for the thermal processed samples compared to the as-sprayed ones, these having a direct influence on the mechanical behavior of the coatings. Although a slight microhardness decrease was observed in the case of vacuum-remelted samples, the overall low porosity and the phase differences helped the coating to perform better during wear-resistance testing, realized using a ball-on-disk arrangement, compared to the as-sprayed reference samples.
