Corrosion tests of three different salt solutions and deionizer
water in combination with five commonly used metals were carried
for medium melting temperature PCM by Cabeza et al. [24].
Similarly, corrosion tests were performed using five different common
metals (aluminum, stainless steel, laminated black steel,
cooper, and galvanized steel) with aqueous salt solutions of NaCl
and KCl during 1 week and 1 month by Yilmaz et al. [55]. Both mixtures
are good PCM candidates because of their low cost and
