In the article the cladded surface on the 42Cr4 steel under high frequency magnetic field were remelted and modified via TIG (Tungsten-Inert-Gas) welding and the tribological proporties of the specimens were analysed after experimenting at the tribosystem – “ball on disc” with paraffin and on the basis of the tribological, physical – mechanical properties the friction coefficient and wear resistnace of them were evaluated. The productivity and quality of the surface via the application of the additional magnetic field to the remelting process have been increased, because of the additional magnetic field in the weld pool. Under the influence of the magnetic field the molten material is rotated and the additional induced temperature increases the melting velocity. The magnetic rotation mix of alloys and gives to the surface high homogeneity.
It has been found that via the plasma treatment of the surface under high frequency maqnetic field the mechanical and tribological properties of the specimens have been improved. The new technology can be applied to the researching and treating of the materials in high frequency magnetic field to increase the quality and efficiency of the processes, So that the methods can be applied for increasing the Hertzian contact pressure, their tribological properties and repairing of the parts.
