Abstract The article presents a mathematical model describing the behavior of a rotating metal brush wire piles during its contact interaction with the surface in deformation cladding by flexible tool. Unlike prior models, based on the analysis of the contact
zone compressed-bent piles with a surface on the sliding area, the proposed model takes into account the oscillating nature of its relative displacements from the entrance to the zone of contact and throughout the whole period of contact. That allow to reasonably choose of rational technological regimes of cladding to form a functional quality of coatings.
Keywords deformation cladding, flexible tool, rotating metal brush, brush wire piles, coatings

Abstract Based on Guber-Mizes criterion and solutions of problems for disk with unit thickness, pressing by two opposite forces, and elastic sphere under compression by two rigid plates, the strength of spherical granules are estimated. The ultimate stress, corresponding to failure beginning, is determines taking into account the first considerable reducing of force on compression diagram. The calculated estimates for granules of capsulated fertilizer show that repeating pelleting of seeds allows us to increase its strength essentially (about 30 %).
