Sentence examples for super hardness from inspiring English sources
The super hardness in nano-composite thin films is obtained when the small crystallites are detached by a discrepant boundary with the high cohesive strength (Patscheider et al).

Using state-of-the-art theoretical calculations, we show that Hex-C18 not only possesses a high thermodynamic stability, large heat capacity, high Debye stiffness, anisotropic elasticity, and super hardness, but also is a promising anode material for lithium ion batteries (LIBs).
The film retained super hardness of above 47 GPa even at 1100 °C due to the formation of crystalline SiNx and the minute c-(Al, Si N layer between c-TiN layers and h-AlSiN layers which delayed the transformation of (Al, Si N from cubic phase to hexagonal phase.
When the nitrogen content is in the low range, e.g. 3 at.%, the Ti B C N coating was characterized as a mixture of Ti(B,C) nanocrystallines and small volume fractions of free carbon, amorphous BN and CNx, where a super hardness of 48.5 GPa has been achieved.
Carbon offers the kind of flexibility that one needs in the design and production of chemically unique microstructures with properties ranging from superlubricity to super-hardness and/or -softness.
For example, such coatings can be tailored in a very special way that while one of the phases can favorably react with certain additives in engine oils to result in an ideal chemical boundary film; the other phases can provide super-hardness and hence resists wear and scuffing.
The measurement of indentation hardness on super-hard nanocomposite coatings: nc-TiN/a-Si3N4 and nc-TiN/a-BN is investigated.
Super high hardness alone does not have too much use.
The MgZn2 type Laves phase of Co3Mo2Si has very attractive super high hardness and covalent dominated bonding nature for wear resistance applications.
