Wear-Resistance Increase of Friction Surfaces of Steel Machine Parts by Electro-Mechanical Hardening

Resumo

The electro-mechanical treatment (EMT) technology of steels is considered. The regularities of hardening treatment modes, in particular of the current density when EMT is established and optimized, provide an ideal surface layer quality and increase the friction surface’s wear resistance. The parameters of the surface layer quality after electro-mechanical hardening were studied. The tribotechnical tests were carried out in order to compare with wear-resistant coatings fabricated by traditional treatment methods.
