'has high hardness' is a correct and usable phrase in written English.
You can use it when referring to the hardness of a material, either physical or figurative. For example: "The steel alloy is renowned for its high hardness and strength."
TiC is a hard brittle phase with a high melting point, so it has high hardness characteristics.
The results show that the alloy cladding layer is high strength, has high hardness, and is highly resistant to wear.
After post-aging, the α″-Fe16N2 phase which has high hardness was formed by decomposing the compound layer.
More importantly, the superhydrophobic surface has high hardness and stable mechanical abrasion resistance, which will highly improve the performance of superhydrophobic surface in engineering and some harsh environments.
The surfaces were formed from nickel, which has high hardness and corrosion resistance, making it suitable for use in harsh environments.
The (Cr,Fe 7C3 carbide reinforced composite coating has high hardness and excellent wear resistance under dry sliding wear test conditions.
The low-Si-content Ta Si N films has higher hardness than high-Si-content (≥ 20 at.%) ones due to lower fraction of soft amorphous SiNx.
While the optimized TiB2/Cu cermet exhibits hardness and fracture toughness of ∼17 GPa and ∼11 MPa m1/2, respectively, the optimized ZrB2/Cu cermet has higher hardness of ∼19 GPa and fracture toughness of ∼7.5 MPa m1/2, respectively.
Nanoindentation tests show that c-plane GaN is less susceptible to plastic deformation and has higher hardness and Young's modulus than the nonpolar GaN.
This is due to the fact that hard brine or formation water having high hardness concentration leads to unfavourable solid precipitations and thus reducing the ASP efficiency.
Recently, a microwave plasma-assisted CVD technology was developed to increase the diamond growth rate, and by adding nitrogen gas, this process can produce nano-structured coatings which consist of nano-diamond crystals embedded into a hard amorphous diamond-like carbon matrix and have high hardness and low surface roughness.
