    摘要:

    提出了一種燒結(jié)后閉孔加工再開孔的策略，通過粉末冶金方法和后續(xù)加工處理制備出了高孔隙率的微孔鎳材料。采用粒徑為1 μm的羰基鎳粉為原料，研究了燒結(jié)工藝參數(shù)對多孔鎳的孔隙性能和力學(xué)性能的影響。結(jié)果表明，在400 ℃燒結(jié)溫度下，壓汞法測得微孔鎳的孔隙率為53.7%，平均孔徑為612.25 nm。經(jīng)加工處理后的壓汞孔隙率為54.0%，平均孔徑為511.37 nm，加工后孔隙結(jié)構(gòu)仍符合應(yīng)用要求，為多孔鎳及其他多孔金屬材料的制備開辟了一條新的途徑。

    Abstract:

    The strategy of sintered closed-hole followed by reopening was proposed to prepare the microporous nickel material with high porosity through the powder metallurgy and subsequential treatments. The carbonyl nickel powder with particle size of 1 μm was used as raw material, and the effects of sintering process parameters on the pore properties and mechanical properties of microporous nickel were studied. Results show that the porosity measured by mercury injection method of microporous nickel is 53.7%, and the average pore diameter is 612.25 nm at the sintering temperature of 400 °C. After machining, the porosity measured by mercury injec-tion method is 54.0%, and the average pore diameter is 511.37 nm, which still satisfies the requirements of engineering application. The strategy provides providing a new approach for the preparation of microporous nickel and other porous metal materials.
