“…Especially in contact with the predominant titanium alloy Ti6Al4V CaZrO 3 showed a remarkable corrosion resistance when used as investment casting molds. The direct comparison with commercially available molds based on Y 2 O 3 revealed a much lower hardness increase, an excellent demolding and metallic shiny color [46,47]. However, as was demonstrated by Schafföner et al [44], c-ZrO 2 impurities cause a stronger corrosion during vacuum induction melting experiments resulting from the dissolution of zirconium and oxygen.…”

“…The phase purity and density of BaZrO 3 for refractory applications can be improved by doping, for example with Y 2 O 3 , CaO or TiO 2 [43]. CaZrO 3 was evaluated in recent years in contact with commercially pure titanium (cp-Ti), Ti6Al4V, titanium aluminide (TiAl) and TiFe [44][45][46][47][48]. Especially in contact with the predominant titanium alloy Ti6Al4V CaZrO 3 showed a remarkable corrosion resistance when used as investment casting molds.…”

“…Дослідження останніх років показують, що перспективними матеріалами для лицьового покриття керамічних форм є CaZrO 3 та BaZrO 3 . Зокрема в [20] виявлено, що реакція форми на основі цирконату кальцію CaZrO 3 з титаном була дуже низькою. Дослідження [21] показали, що обсипка керамічних форм Al 2 O 3 реагувала з наповнювачем CaZrO 3 лицьового покриття, утворюючи (Zr, Ca)O 2 і CaAl x O y при температурі близько 1650 0 C. При використанні ZrO 2 в якості обсипки не спостерігалося взаємодії, за винятком деяких тріщин, що виникали в лицьовому покритті внаслідок зміни об'єму ZrO 2 під час його нагрівання.…”

“…Titanium alloys are ideal materials for aerospace and military applications due to their advantages of low density, high-temperature resistance, high speci c strength, and corrosion resistance [1][2][3][4][5][6]. e successes of applying titanium alloys have largely been the result of pragmatic engineering as opposed to bottom-up scienti c discovery and application [7].…”
