在纯铁中用磷作为合金化元素的好处已得到证明。这些好处包括提高直流磁性能,提高烧结密度及力学性能。铁中加入合金元素磷的一个主要缺点是模具易于磨损。用一种先进的粘结剂处理方法,在用传统粘结剂处理的预混粉烧结体密度<7.0 g/cm3和使用温压烧结体密度>7.2 g/cm3的材料的试验中,观察到脱模力与滑动力减低。这种脱模力与滑动力的减低,有可能使模具磨损最小化。本文将介绍这种新材料的力学性能与磁性能。
The benefits of using phosphorus as the alloying element in pure iron have been demonstrated. These benefits include increased DC magnetic properties, improved sintering density and mechanical properties. One of the major disadvantages of adding alloying elemental phosphorus to iron is that the mold is prone to wear. With an advanced binder treatment, in the tests of pre-mixed powder sintered body density <7.0 g / cm3 treated with a conventional binder and using a material with a warm-pressed sintered body density> 7.2 g / cm3, it was observed Stripping force and sliding force reduced. This stripping force and sliding force reduction, it is possible to minimize mold wear. This article will introduce the mechanical properties and magnetic properties of this new material.
