“…It is noted in the work [14] that, in the case of wire electrocontact surfacing, its plastic deformation leads to a shift in the welded metal volumes on the surface of the part both in the radial (across the welded metal seam) and in the axial (along the welded metal seam) directions. According to the work [14], experimental data indicate an increase in the strength of the bond between the deposited wire and the part with increasing axial deformation. However, the axial deformation in this work was controlled by changing the temperature parameters of the surfacing conditions and this complicates the assessment of the deformation processes impact on the increase in strength of the resulting welded layer.…”

The finite element modulation of forming of coating at electric contact surfacing is provided. This model considers distribution of thermal properties and geometric parameters along the thermal deformation zone during the process of electric contact surfacing by tapes. It is found that the change of the value of the speed asymmetry factor leads to increasing of the friction coefficient in the zone of surfacing which is caused by the increasing of the tangential contact stresses in the zone of contact of the electrode tape with the surface of the part. This leads to the forming of the coating with higher adhesion strength, and thereby the higher quality of the restored part under the lower operating regimes such as current pulse, force of the roller electrode, and duration of the current pulse is achieved. Mentioned above allows to decrease the thermal influence on the structure of the material.
