Method for quantitative description of grease adhesive interactions with the surface, especially the surface of the steel

摘要

a quantitative description of adhesive lubricant plastic surface, especially the surface of steel, in which the test discs (1) or (1 ') of a fixed diameter and a fixed roughness applied grease, and then at the free surface of the grease is placed second tarc that test (1) or (1 '),after which the discs (1) or (1 ') is secured in the machine for testing the tensile strength and open them with constant speed until a complete break a layer of grease and separation discs (1) or (1'), after what it does, and obtained image surface of the discs are series land of thethat: fixed area analysis; filtered area analysis using filter krawu0119dziowego method dog (difference of gaussians); in the area of analysis determined edges in operation zero - crossing; made dilation area edge; determined the difference between the images the area analysisand the function of graphic area edge; shall be labelled bordering areas representing areas alternately shield test covered in grease (5) and the areas free from grease; counts to pixels belonging to areas representing fragments covered with grease and ob test disc method of representing test disc with grease; calculated adhesion coefficient "and".
