A Ni aluminide layer containing Zr and Hf was formed on a Ni specimen by the synchronous electrodeposition of Al-Zr and Al-Hf using a molten-salt bath. An electrodeposited layer consisting of Ni_2Al_3 and NiAl_3 layers, for which the ZrAl_3 particles were formed on the surface region, was formed, when the simultaneous electrodeposition of Al and Zr was carried out using the molten NaCl-KCl containing 3.5mol% AlF_3 and 0.05mol% ZrF_4. An electrodeposited layer consisting of Ni_2Al_3 and NiAl_3 layers, for which the HfAl_3 particles were formed on the surface region, was formed, when the simultaneous electrodeposition of Al and Hf was carried out using the molten NaCl-KCl containing 3.5mol% AlF_3 and 0.05mol% HfF_4. The cyclic-oxidation resistance of the Ni specimens covered by the Ni aluminide layer containing the ZrAl_3 and HfAl_3 particles was evaluated in air at 1423K. The sample covered with the Ni aluminide containing the ZrAl_3 and HfAl_3 particles, which was formed using the melt containing 3.5mol%AlF_3-0.05mol%HfF_4 and 3.5 mol%AlF_3-0.05mol%HfF_4, showed a high cyclic-oxidation resistance. On this sample after the oxidation test, an adhesive scale having a spiked shape, which consisted of Al_2O_3 as the outer layer and ZrO_2 or HfO_2 as the inner layer, was formed.

通过使用熔盐浴同步电沉积Al-Zr和Al-Hf，在Ni样品上形成含有Zr和Hf的Ni铝化物层。当使用含有3.5mol％AlF_3和0.05mol的熔融NaCl-KCl同时进行Al和Zr的电沉积时，形成了由Ni_2Al_3和NiAl_3层组成的电沉积层，其表面区域上形成了ZrAl_3颗粒。 %ZrF_4。当使用含有3.5mol％AlF_3和0.05mol的熔融NaCl-KCl同时进行Al和Hf的电沉积时，形成了由Ni_2Al_3和NiAl_3层组成的电沉积层，在该电沉积层的表面区域上形成了HfAl_3颗粒。 %HfF_4。在1423K的空气中评价了被含有ZrAl_3和HfAl_3颗粒的Ni铝化物层覆盖的Ni样品的耐循环氧化性。使用含有3.5mol%AlF_3-0.05mol%HfF_4和3.5mol%AlF_3-0.05mol%HfF_4的熔体形成的被含有ZrAl_3和HfAl_3颗粒的Ni铝化物覆盖的样品表现出高的抗循环氧化性。在该氧化试验后的样品上，形成了由Al_2O_3作为外层、ZrO_2或HfO_2作为内层组成的尖刺形状的粘着氧化皮。
