ANALYTICAL APPROACH TO DETERMINING OF PARAMETERS WHICH CHARACTERIZE SURFACE LAYER QUALITY OF THE PARTS HARDENED BY A TRAVELING DIAMOND SPHERE

摘要

The present work is dedicated to analysis of a plane boundary problem of a sphere movement along an elastic semi-plane. Moreover it is supposed that in the area of contact between the sphere and the semi-plane there will be sectors with multidirectional frictional load as well as a sector with adhesive bonds. By means of the received solution of the boundary problem we?ve evaluated the area of plastic deformation below the sphere based on the condition of equality of load and plasticity invariable (yield point ( )). Plastic deformation height was considered to be the maximum height of plastic deformations penetration under the traveling sphere. Comparison of experimental and estimated data demonstrated accuracy acceptable for use of the elaborated method in real production.
