摘要：
FIELD: monitoring devices.SUBSTANCE: invention relates to means of controlling microroughnesses of surfaces, obtained by mechanical engineering operations on a rough surface, for example paraffin, wax, refractories, etc. Claimed hydrophobic surface roughness non-contact fractal control method is that the hydrophobic surface under investigation is cleaned by plasma-chemical etching under the inert gas environment under conditions preventing the investigated surface material sputtering. Immediately after cleaning, a liquid in the form of the fixed volume drop is applied to the surface; by means of high-speed digital video recording two times registering time of the fixed volume liquid drop spreading along the investigated hydrophobic surface and at the fixed volume liquid drop spreading cessation times, determining the spread liquid drop perimeter and area. Wherein the spread liquid drop perimeter and area second registration is carried out after that, by means of the oscillations source with a controlled frequ
