contact angle

Purpose of work is study of wettability of samples processed by ionic implantation. In the paper wettability was determined by optical method. Wetting angles was determined by using the camera for three types of fluids: water distilled, ordinary tap water and mineral sparkling water. Due to the research it was found that the contact angle of droplets of distilled water for implants less than for steel. This is consistent with theoretical predictions, because roughness increases during implantation. In the case of tap water difference between contact angles decrease.
