The electrochemical measurements allowed to determine a corrosion potential, which showed a positive shift from –1.60 V for Ca65Mg17.5Zn17.5 alloy to –1.58 V for Ca60Mg17.5Zn22.5 alloy, adequately. The more significant decrease of hydrogen evolution was noticed for Ca60Mg17.5Zn22.5 alloy (22.4 ml/cm2) than for Ca62.5Mg17.5Zn20 and Ca65Mg17.5Zn17.5 samples (29.9 ml/cm2 and 46.4 ml/cm2), consequently. The corrosion products after immersion tests in Ringer’s solution during 1 h were identified by X-ray diffraction and X-ray photoelectron spectroscopy as calcium, magnesium oxides, carbonates, hydroxides and calcium hydrate.}, type={Artykuły / Articles}, title={Corrosion Properties of Ca65–xMg17.5Zn17.5+x (x = 0, 2.5, 5) Alloys}, URL={http://www.czasopisma.pan.pl/Content/113020/PDF/AMM-2019-3-39-Babilas.pdf}, doi={10.24425/amm.2019.129492}, keywords={Ca-based alloys, Corrosion, Hydrogen evaluation, X-ray photoelectron spectroscopy (XPS)}, }
