| 摘 要： | 研究了在二氧化锆与不锈钢的混合粉末中加入粘结剂时的挤压成形特性，并着重考察了混合粉的可挤上限条件，所用粘结剂为水溶性羟丙基在纤维素（ＨＰＭＣ）和水，结果表明，混合粉末的可挤压上限成分（质量分数）随不锈钢粉末含量的增加而上升，当不锈钢的粉末含量（体积分数）为７０－９０％时达到最大，粘结剂中ＨＰＭＣ的质量分类以１０％为宜。

| Abstract: | The extrustioncharacteristics of composite powders of stainless steel and zirconiahave been researched experimentally, and the upper extruded composition of the composite powders being discussed. Hydroxy-propyl methyl-cellulose (HPMC) and water was used as the binder for the extrusion. The results show that the extrudable upper compositionincreases with increasing the stainless steel powder content in composite powder, and that the reasonable content of HPMC in the binder being 10%. |
