阳极氧化法测定烧结多孔体表面积

THE MEASUREMENT OF SURFACE AREA OF SINTERED POROUS MATERIALS

摘要: 在烧结动力学的研究中,通常要测定烧结体的表面积。本文提出了用阳极氧化法测定阀金属烧结多孔体的表面积。经比较各种计算方法,认为采用氧当量法可得到较好的结果。

Abstract: For the investigation of sintering kinetics, the surface area of sintered compacts is conventionally measured. The present paper outlines that the surface area of sintered porous metal for valve can be measured by anodic oxidation. Comparison was made between various calculating methods. It is concluded that better results can be obtained by oxygen equivalent method。
