The phrase "although hardness" is not correct and usable in written English as it lacks context and clarity.
It could potentially be used in a sentence that contrasts hardness with another quality or condition, but it needs additional information to be meaningful.
Example: "Although hardness can be a desirable trait in materials, flexibility is equally important in certain applications."
Alternatives: "despite the hardness" or "even though it is hard".
Although hardness is widely considered a viable index to measure the integrity of the cement structure, there are few specific studies involving changes in hardness characteristics of BIBCs post elution of high doses of two widely used antibiotics: tobramycin and gentamicin.
Because of the strong covalent-dominated atomic bonds and high volume fraction of the ternary metal silicide Mo2Ni3Si, both the original and the aged Mo2Ni3Si/NiSi coating has excellent wear resistance under pin-on-disc high-temperature sliding wear test conditions, although hardness of the aged coating is slightly lower than that of the as-clad coating.
Although the hardness of bi-antibiotic-impregnated bone cement (BIBC) pre- and post elution is of much significance, there are few specific studies on this important biomechanical characteristic.
Although coatings hardness increased with increasing ceramic particle content, the effect on the coatings wear performance is not that significant.
Although the hardness of the tablet increased following MW treatment, the disintegration time became less than that of the MW-untreated tablets as the β-mannitol ratios increased.
The addition of another element, such as carbon, can improve the mechanical properties, although the hardness of for example W S C coatings is still rather low.
The wear rates and friction coefficients of these rejuvenated samples depend mainly on the possibility of forming lubricious Cu films, although film hardness also played a certain role.
Although the hardness reached HRC65 at room temperature, the value of m = 0.38 and flow stress of 57 MPa were found during superplastic forming at 1023 K and strain rate of 10−4 s−10−4
Although the hardness is roughly constant in the here investigated MoS2 concentration range at constant temperature, the lowest amount of MoS2 (0.2 at.%) increases substantially the hardness of Si3N4 MoS2 thin films at 23 °C.
The wear test results revealed that wear rate of all the coatings increased with increasing load and that the blend coatings showed better wear resistance than the pure molybdenum coating, although the hardness was lower.
For the AlCrSiN single layer coatings, the erosion depth curves changed linearly, and their erosion rates became remarkably larger with increasing (Al + Si) concentration although the hardness decreased gradually.
