Abstract

A, B, T를 Arc 용해방법으로 고용 상태인 AB2TX합금을 제조하고, 이 합금을 분쇄하여 합금 분말을 제조한 후, 상기 합금 분말을 알칼리로 처리하여 T를 제거하여 제조한 AB2합금은 수산화칼륨 전처리 공정에서 용출되어 나오는 금속이나 금속 산화물의 양만큼의 금속T(V이나 Zr, Mn)을 더 첨가하였기 때문에, 금속이나 금속 산화물 용출에 의하여 발생하는 표면 화학정량의 변화를 억제할 수 있고, 합금의 기공률이 증대되므로 반응 면적이 커지게 되고, 기공률을 임의로 조절할 수 있으며, 알칼리 전처리 과정을 거친 후 표면 조성 변화가 최대한 억제된 원하는 조성의 합금을 얻을 수 있는 효과가 있다.AB 2 T X alloy in solid solution A, B, and T was prepared by Arc dissolution method, and the alloy powder was pulverized to prepare an alloy powder, and the alloy powder was treated with alkali to remove T 2 AB 2. Since the alloy further added metal T (V, Zr, Mn) by the amount of the metal or metal oxide eluted from the potassium hydroxide pretreatment process, it is possible to suppress the change in the surface chemical quantity caused by the metal or metal oxide elution. It is possible to increase the porosity of the alloy, the reaction area is increased, the porosity can be arbitrarily adjusted, and after the alkali pretreatment process, there is an effect of obtaining an alloy of the desired composition with the maximum change in surface composition.
