Abstract
This article discusses the impact of repair-recovery compositions on the process of buildup of the soil working bodies of earthmoving machines. Adhesive forces can be reduced by creating an intermediate layer at the interface between the phases of the system “surface of the working member - the medium to be treated. This layer serves as a screen for intermolecular interaction forces of phases, has a small adhesion and cohesive interaction and has a “lubricating” effect, i.e. provides the possibility of relative displacement of phase working surfaces. Experimental work is conducted in accordance with the mathematical theory of planning of experiments (plan Box 3). After handling of an experiment graphical dependences of effort of shift from a surface without repair and recovery structures and with use of repair and recovery structures were received. The experiments carried out showed that when the RVS is applied, the adhesion of the soil to the metal surface of the digger’s working member is reduced by an average of 18%.
