... the hardness and wear resistance, whereas the humidity-sensitive alumina phase reduced friction at higher humidity levels. Next, CuO (5 wt%) was added to the Al 2 O 3 -B 2 O 3 composites to form Al 2 O 3 -B 2 O 3 -CuO composites. These composites showed an increase in the percentage relative density by 16–37...

...G. Vedabouriswaran; S. Aravindan Friction stir processing is performed on RZ 5 Mg alloy to produce surface metal matrix composites reinforced with hard reinforcement particles. Boron carbide, multiwalled carbon nanotubes, and a mixture of zirconia and alumina particle reinforcements were introduced...

... a Berkovich tip and single crystal alumina and silica samples, are implemented in the proposed area function yielding estimated values of Young’s modulus. Results were compared with that obtained from Oliver and Pharr technique for deep as well as shallow indentation regimes. The estimates for Young’s modulus...

... for alumina ceramic seals to reduce the ceramic-to-ceramic wear. As a result, leaks are very commonly observed from water pump during services. Consequently, it is needed to improve the surface properties of the ceramic seals using a surface modification technique such as a thin film coating process to meet...

.... The wear specimens were 8 mm in diameter and 12 mm in length. The counter disk material was 314 stainless steel (hardness 80-90 HRB). Before wear test, each specimen was ground with 1 μ m alumina suspension and the counter disk was ground by 2000 grit SiC paper. Wear tests...
