制备了Ni3Al金属间化合物,并研究了该材料的耐腐蚀性。结果表明,Ni3Al金属间化合物烧结之后孔隙、孔径以及体积膨胀都随温度的升高而变大。而且,Ni3Al金属间化合物在KOH溶液中具有较强的抗腐蚀特性。
The Ni3Al intermetallic compound was prepared and the corrosion resistance of the material was studied. The results show that the porosity, pore size and volume expansion of Ni3Al intermetallics increase with the increase of temperature. Moreover, Ni3Al intermetallic compounds have strong corrosion resistance in KOH solution.
