Corrosion properties of electrodeposited Cu/Co multilayers

The paper presents the results of corrosion resistance of Cu/Co multilayer systems fabricated by using the electrolytic method. The systems obtained were composed of layers differing in number and thickness, which was determined by observing the cross-sections of the samples using scanning electron microscopy (SEM). The measurements of multilayer system corrosion properties carried out in 3,5 % NaCl solution showed different corrosion resistance depending on system thickness. The microscopic observations revealed the effect of the aggressive environment on the Cu/Co multilayer systems manufactured, adopting various forms of corrosion degradation

Influence of boron and silicon on the magnetic properties of iron- based alloys

W pracy przedstawiono wyniki badań struktury i wybranych własności magnetycznych szkieł metalicznych na osnowie żelaza. Próbki do badań w postaci taśm wytworzono metodą “melt spinning”. W ramach badań własności magnetycznych wyznaczono indukcję nasycenia oraz natężenie pola koercji i wartość namagnesowania. Zakładając, że namagnesowanie można podobnie zdefiniować jak w przypadku paramagnetyków (klasyczna teoria ferromagnetyzmu wykorzystująca model pola molekularnego – pola Weissa) opracowano metodykę opisu własności magnetycznych dla badanych stopów amorficznych. Ilościowy wpływ pierwiastków stopowych (B,Si) na własności magnetyczne badanych materiałów pozwolił określić wartość współczynnika mocy wpływu β, której wielkość zastępuje stałą pola molekularnego.The paper presents the results of structural and magnetic properties of selected iron- basedmetallic glasses. The samples in the form of tapes were prepared by "melt spinning".The study of the magnetic properties were determined saturation induction,magnetic coercivity and value of the magnetization. Taking advantage of the fact that the magnetization is defined similarly as in the case of paramagnetics (a classic theory of ferromagnetism that uses molecular field model –Weiss field) description model of the magnetic properties of amorphous material. Quantitative impact of alloying elements (B, Si) on the magnetic properties of the material allowed to determine the effect of power factor β , which replaces the fixed constant of molecular field
