Measurement of contact adhesion and atration between engineering surfaces

摘要

A contact adhesion meter devised with a sensitive electromagnetic scale with negative feedback served to investigate the forces of adhesion between the specimens from steel, silicon and titanium oxide shaped as a silicon sphere. Controllable feed of the specimens to the test body has enabled to determine the relation between the forces affecting the bodies and the spacing between them. The results of measurement of the work of adhesion, interphase energy and the effect roughness on the force of adhesion correlate well with the known experimental data and theoretical assessments.
