【摘要】：采用Micro-FAST技術(shù)成功制備出多孔NiTi合金,燒結(jié)時(shí)間短,成本低,節(jié)能環(huán)保。研究結(jié)果表明,隨著燒結(jié)溫度的升高,試樣的孔隙度先減小后增加,再略微減小,有害相NiTi_2和Ni_3Ti減少,趨于形成NiTi單相。當(dāng)燒結(jié)溫度為1100℃時(shí),試樣孔隙分布均勻,隨著燒結(jié)保溫時(shí)間的延長(zhǎng),燒結(jié)試樣孔隙度高達(dá)32.2%,孔徑范圍在100μm左右,符合人體骨組織植入物的要求。
[Abstract]:The porous Niti alloy was successfully prepared by Micro-FAST technology. The sintering time was short, the cost was low, and the energy saving and environmental protection was achieved. The results show that with the increase of sintering temperature, the porosity of the sample decreases first, then increases, then decreases slightly, and the harmful phases NiTi2 and Ni3Ti decrease and tend to form Niti single phase. When the sintering temperature is 1100 鈩，
