“…The complete TBCs system mainly consists of three components: ceramic top‐coating, bond coating, and super‐alloy substrate, respectively. Since TBCs need to operate under thermal‐cycling conditions, the difference of TECs can result in thermal stresses between different coatings, and ultimately lead to coatings failure . Typically, bond coating and super‐alloy substrate possess higher TECs (∼14 × 10 −6 k −1 ) than ceramic top‐coating .…”

In this work, RENbO4 (RE = Y, La, Nd, Sm, Gd, Dy, Yb) ceramics with low density, low Young's modulus, low thermal conductivity, and high thermal expansion have been systematically investigated, the excellent thermo‐mechanical properties indicate that RENbO4 ceramics possess the potential as the new generation of thermal barrier coatings (TBCs) materials. X‐ray diffraction and Raman spectroscopy phase structure identification reveal that all dense bulk specimens obtained by high‐temperature solid‐state reaction belonged to the monoclinic (m) phase with C12/c1 space group. The ferroelastic domains are detected in the specimens, revealing the ferroelastic transformation between tetragonal (t) and monoclinic (m) phases of RENbO4 ceramics. The Young's modulus and hardness of the RENbO4 ceramics measured by the NanoBlitz 3D nanoindentation method are discussed in details, and the lower Young's modulus (60‐170 GPa) and higher hardness (the maximum value reaches 11.48 GPa) indicating that higher resistance of RENbO4 ceramics to failure and damage. Lower thermal conductivity (1.42‐2.21 W [m k]−1 at 500°C‐900°C) and lower density (5.330‐7.400 g/cm3) than other typical TBCs materials give RENbO4 ceramics the unique advantage of being new TBCs materials. Meanwhile, the thermal expansion coefficients of RENbO4 ceramics reach 9.8‐11.6 × 10−6 k−1 and are comparable or higher than other typical TBCs materials. According to the first‐order derivative of the thermal expansion rate, the temperature of the ferroelastic transformation of RENbO4 ceramics can be observed.

“…Rickerby and Winstone [13] put forward that the surface coatings help to deal with the physical and chemical degradation of the surface. The fracture toughness of Al 2 O 3 coatings can be enhanced by the addition of TiO 2 particles clad in the form of layers [14]. Thermal spraying is an effective and economical route to develop thick and uniform coatings for the surface modification of a part [15].…”

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.
