Fe-based amorphous coating technology is recognized as an attractive surface modification method owing to superior physical and chemical properties. Novel FeCrNiMoCBSi coatings were prepared on marine F22 steels by plasma spraying with various spraying powers. Morphologies and microstructures were characterized by scanning electron microscope (SEM), x-ray diffraction (XRD), transmission electron microscope (TEM) and differential scanning calorimetry (DSC). Results showed that the as-sprayed coatings were mainly composed of amorphous and nanocrystalline phases. Spraying power had an effect on the combination of the phase compositions and defects in the assprayed coatings. Besides, the increase in spraying power accelerated the melting of feedstock materials, and reduced the unmelted particles existed in the coatings, but aggravated oxidization of melted particles. Spraying power affected the cooling rate, which was related to the heat input and pre-deposited surface temperature. The optimized spraying power was 35 kW, and the coating possessed an amorphous phase content of 67.8% and a defect ratio of 0.99%. Furthermore, the nanoindentation measurements showed that amorphous phase determined performance characteristics while the defects in coatings provoked local imbalances in mechanical properties. Besides, the electrochemical corrosion methods indicated that the coating sprayed at 35 kW displayed better corrosion resistance in marine environment, which was attributed to the optimized microstructure. This research not only extends the application of Fe-based amorphous coatings on marine steels, but also provides a brief sight on the relationship between processing, microstructures and properties.fields [9,10]. Thermal spraying technologies have attracted considerable attention in terms of the surface modification or / and remanufacture of materials and machines. Liu et al [11] have emphasized the advantages of plasma spraying such as simplicity and flexibility. The theoretical cooling rate of the molten droplets is up to 10 7 K s −1 [12], providing a guarantee for the formation of the amorphous phase. Furthermore, in terms of ultra-high temperature characteristics and high formation efficiency, the Fe-based amorphous coatings via plasma spraying possess high bonding strength and excellent compactness. Recently, many extensions of researches on corrosion and wear resistances have confirmed wide applications of plasma-sprayed Fe-based amorphous coatings under harsh environment.

“…Numerous oxide ceramics like alumina, silica, zirconia, titania, and chromium find widespread applications as potential materials for surface coatings and thermal barriers and for enhancing erosion, wear, abrasion, and corrosion resistance [5,6]. Plasma spraying has been the prominent thermal deposition method in this regard [7][8][9]. When spraying for coating, the molten particles collide to build a layer of coating with superior thermo-mechanical properties.…”

In this report, a study of the wear mechanisms involved in spinning Ring and Traveler of textile industry have been presented. These components, after surface processing with various coatings techniques, were analyzed on the test rig to analyze the wear mechanism. The objective was accomplished by comparing various plasma sprayed coatings on E52100 steel pins using a Pin-on-Disc machine. The surface morphology as well as mechanical properties of the deposited coatings namely WC-Co-Cr, Al2O3+TiO2 (Alumina-Titania) and Cr3C2NiCr, as well as uncoated E52100, were comparatively studied. This study elucidates towards improving the working life of the Ring in a Textile mill while spinning operation. An X-ray diffractometer (XRD) and Scanning Electron Microscope (SEM) was employed to characterize the unworn and worn surfaces of the specimens. The study revealed that the wear rate of Plasma sprayed thermal coatings enhanced with augmenting load. The Plasma sprayed WC-Co-Cr, Cr3C2NiCr, Al2O3+13TiO2 coatings developed on workpiece pins exhibited a notable decrease in volume loss of the material as compared to uncoated E52100 substrate. WC-Co-Cr coating turned out to be the best performer in terms of lowest cumulative volume loss among all the variants of coatings.
