“…Various natural ores, minerals, and mine wastes have been thermally sprayed recently onto metal substrates to achieve desired properties like corrosion, thermal, electrical, and wear resistance. − Some of the materials used in these coatings were ilmenite, garnet, olivine, hydroxyapatite, and basalt. , Natural materials such as diopside, forsterite, and tourmaline were studied as an alternative to ceramic type materials for electrical, thermal, and wear resistance properties. ,, Ceramics and minerals both have the ability to withstand their integrity at elevated pressure and temperatures; therefore, they can be used in harsh environmental conditions due to their sustainability and high melting temperatures . Thermal spray method like atmospheric plasma spraying (APS) has been extensively used to study high melting temperature materials such as ceramics and minerals. ,− APS can generate temperature up to 15,000 °C and this technique is best suited for materials with higher melting points as it gives higher particle temperature as compared to others, which result in a thicker coating on the substrate. , Particle temperature in APS depend on certain parameters like feeding rate of particles, distance of substrate from gun, particles size and distribution, and so forth. Both particle temperature and velocity at impact are strongly dependent on starting powder particle size and morphology .…”

Natural materials are gaining interest as coating feedstock because their “quality to cost” ratio is better and they are more environmentally friendly than most of the synthetic ceramics. They give sufficient protection to metal surfaces against harsh conditions such as corrosion, wear, and high temperature. In the current study, chromite mineral was beneficiated and reduced to two different sizes to be used as feedstock material for thermal spray coating. Powders were upgraded by gravity and magnetic separation, respectively, and thermally sprayed onto mild steel samples by using atmospheric plasma spray (APS) equipment. Morphology, structure, phases, elemental distribution of chromite powder, and coatings were studied using field emission scanning electron microscopy, X-ray diffraction, X-ray fluorescence spectroscopy, and energy-dispersive X-ray spectroscopy. Tribological properties of APS chromite coatings were investigated by using a ball-on-disk tribometer, and corrosion resistance properties were evaluated by carrying out potentiodynamic polarization testing in 3.5% NaCl solution. It is observed that the coating has better wear and corrosion resistance and is worn by abrasive wear that includes scratching and particles pull out. Coating efficiency, surface morphology, and microhardness of the coating developed by fine powder were better than those of coarse powder coating.

Ti 3 SiC 2 /cordierite coatings with different critical plasma spray parameters (CPSP) were fabricated via atmospheric plasma spraying method. The microstructure and phase constitution of the as-sprayed Ti 3 SiC 2 /cordierite coatings were characterized. The effects of CPSP conditions on the electromagnetic shielding, and dielectric and microwave absorption properties of coatings in the frequency of 8.2-12.4 GHz were also measured and investigated. The results showed that both real and imaginary part of the complex permittivity decrease with increasing CPSP values, which can be ascribed to the decomposition of some Ti 3 SiC 2 into TiC. The calculated reflection loss of the as-sprayed Ti 3 SiC 2 /cordierite coatings with different CPSP conditions and thicknesses indicates that coatings with CPSP 0.3, 0.35, and 0.425 exhibit excellent microwave absorption property in the thickness of 1.5 mm. In order to broaden the bandwidth of the coatings, a double-layer coating system was designed. The calculated reflection loss results show that when the thickness of matching layer is 0.3 mm and the thickness of absorbing layer is 1.5 mm, the double-layer coating system shows a proper microwave absorption property with a minimum absorption value of 217.37 dB at 9.67 GHz and a absorption bandwidth (RL less than 25 dB) of 4.16 GHz in the investigated frequency.
