The phrase "a lower coefficient of" is correct and usable in written English.
It can be used in contexts related to mathematics, statistics, or scientific discussions where coefficients are being compared.
Example: "In this study, we found that the new material has a lower coefficient of thermal expansion than the previous one."
Alternatives: "a reduced coefficient of" or "a diminished coefficient of".
The study shows that the HVOF-sprayed coatings had a lower coefficient of friction.
In a dry environment, textured ZTA surfaces have a lower coefficient of friction than untextured ZTA surfaces.
The F12 also has a lower center of gravity, increased torsional rigidity, better weight balance, a lower coefficient of drag and more precise steering response.
It is call BAM for Boron Aluminium Magnesium ceramic it has 60% the hardness of Diamond and a lower coefficient of friction than PTFE or wet ice on wet ice.
Case hardening during diffusion treatment offers a mechanical support to the coating, which exhibits a lower coefficient of friction than the diffusion-treated surface.
BCECs on nanopillars displayed a lower coefficient of variation of area (0.31) that was within the range of healthy corneal endothelium.
The jet refrigeration cycle employing this new feeding system provided a slightly lower coefficient of performance (COP) compared to a system using a mechanical pump.
A driving force behind selecting these coatings was a noticeably lower coefficient of friction at elevated temperatures.
Ball-on-disc tests were used to assess the friction at 700 °C where Al0.70Cr0.05V0.25N coatings revealed a generally lower coefficient of friction due to the formation of a tribolayer containing the lubricious oxide V2O5 as evidenced by Raman spectroscopy.
Sliding results suggest that the tumbled cBN TiN coating has a significantly lower coefficient of friction.
Results show that the refrigerant R290 have a slightly lower coefficient of performance than R134a for the condensation temperature of 35 °C to 43 °C and evaporating temperatures range between −5 °C to 5 °C.
