“…The oscillation of the COF data is observed in all specimens, and it mainly depends on applied load, sample hardness, and surface roughness of the specimen. When the stylus moves with load, the surface gradually deforms and creates an intermediate debris layer on the moving track that makes the wear track rougher and create oscillations in different regions of the coefficient of friction data …”

The effect of addition of submicrometer-sized B 4 C (5,10 and 15 wt%) on microstructure, phase composition, hardness, fracture toughness, scratch resistance, wear resistance, and thermal behavior of hot-pressed ZrB 2 -B 4 C composites is reported. ZrB 2 -B 4 C (10 wt%) composite has V H1 of 20.81 GPa and fracture toughness of 3.93 at 1 kgf, scratch resistance coefficient of 0.40, wear resistance coefficient of 0.01, and ware rate of 0.49 9 10 À3 mm 3 /Nm at 10N. Crack deflection by homogeneously dispersed submicrometer-sized B 4 C in ZrB 2 matrix can improve the mechanical and tribological properties. Thermal conductivity of ZrB 2 -B 4 C composites varied from 70.13 to 45.30 W/m K between 100°C and 1000°C which is encouraging for making ultra-high temperature ceramics (UHTC) component.

ZrB 2 -SiC composites were prepared by hot pressing with different sources of SiC to study the effect of SiC with different morphology on densification, microstructure, phase composition and mechanical properties like hardness, fracture toughness and tribological properties (namely, scratch resistance, wear parameters) and thermal behaviour of the composites. Three different ZrB 2 -SiC composites, i.e. ZrB 2 -SiC P (polycarbosilane derived SiC), ZrB 2 -SiC C (SiC from CUMI, India) and ZrB 2 -SiC H (SiC from H. C. Starck, Germany), were studied. It is found that ZrB 2 -SiC C composite shows highest hardness (19?13 GPa) and fracture toughness (5?30 MPa m 1/2 at 1 kgf load) in comparison with other composites. Interconnected network, better contiguity between grains of ZrB 2 -SiC composites and impurity content in starting powders can play significant roles for achieving high mechanical, tribological and thermal properties of the composites. Coefficient of friction and wear parameters of all ZrB 2 -SiC composites are very low, and thermal conductivity of ZrB 2 -SiC composites varied from 52?71 to 65?53 W (m K) 21 (ZrB 2 -SiC P ), 54?30 to 71?55 W (m K) 21 (ZrB 2 -SiC C ) and 64?25 to 88?02 W (m K) 21 (ZrB 2 -SiC H ), respectively and also calculate the interfacial resistance of all the composites.

“…Many studies have been performed on increasing the scratch resistance and hardness of glass using ceramic coatings . Recently, sol–gel, chemical vapor deposition (CVD), and physical vapor deposition (PVD) methods have attracted great attention because of their ability to reproducibly synthesize high‐quality films.…”

Development of a Transparent Scratch Resistant Coating through Direct Oxidation of Al‐Coated Glass

et al. 2016

The authors develop a protective transparent coating of aluminum oxide through direct oxidation of aluminum-coated glass. Aluminum coatings are deposited on low-iron glass substrates using a physical deposition method and then oxidized at different temperatures. A uniform nano-porous structure with grain sizes of approximately 30-80 nm is observed. X-ray diffraction, TEM images, and EDX analysis indicate the formation of crystalline g-Al 2 O 3 , Si, and stishovite-SiO 2 as a result of interdiffusion. The samples treated at different temperatures have hardness values ranging from 5 to 9 H, which is within the desirable range for industrial scratch-resistant coatings. The optical transmission of around 75-85% at visible wavelengths makes the proposed technique useful for the design of protective transparent coatings. [**] The authors are grateful to the Physical Analysis Group at INM for the structural characterizations and to B. Heiland for TEM sample preparation. We thank Mr. R. Karos for performing XRD measurements and for valuable discussions. We also acknowledge the contributions of B. Schäfer for ellipsometry measurements. The authors would like to thank Prof. R. Bennewitz and Dr. A. Caron for the AFM measurements.
