The effect of compression plasma fluxes on the structure, mechanical and corrosion properties of silicon electrical steel

The work presents the results of a study the effect of treatment with compression plasma fluxes with pulse energy density of 35 J/cm2 on the structure, mechanical and protective properties of silicon electrical steels with silicon content of 6.67 %. Samples were modified with 1, 2, 3 pulses of compression plasma flows in the N-atmosphere at pressure of 400 Pa. By the method of scanning electron microscope it observed that surface of morphology characterizes with craters depending on number of pulses. By the method of X-ray diffraction was established that the lattice parameter increases. Density of dislocations and microhardness increases due high-speed cooling of the modified layer. It was established that the friction coefficient and corrosion resistance increase, due to the formation of a non-uniform melted surface in the CPFs-treated samples and due to formatting a homogeneous remelted layer.
