Wettability of laser micro-textured carbide surface

In order to study the influence of laser micro texture carbide surface on its surface wettability, this paper uses the optical fiber laser power(3,5,7,9,10 W) and machining number (1,2,3,4,5) to get different micro-pores and then uses cultra-depth three-dimensional microscopy and optical microscopy to analyze their microscopy. Optical contact angle meter is used to discuss the relationships between micro-textured surface (diameter, depth and density of micro-pores) and its wettability. The results show that with the increase of the laser power, the micro indentation depth increases while the diameter variation is not obvious, the hydrophilicity of the surface decreases with the increase of micro indentation depth, increases with the increase of the micro-pore diameter and reaches the extremum with the increase of the density of the micro-textured surface.
