4 V surfaces. The study revealed that for varying loads of 10 N, 20 N, and 30 N, the
coefficient of friction (COF) for circular textured surface (CTS) was 33.88%, 24.64%, and
17.11% less, and for cross-hatch textured surface (CHTS) it was 30.49%, 28.30%, and
16.8% less than the COF of untextured surface (UTS). In the presence of the dual textures,
the contact angle of the Phosphate buffer saline (PBS) solution decreased by 1.5–8 …
