摘要
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 utilizing phosphorous as an alloying element in pure iron are well documented.These include improved DC magnetic performance,higher sintered densities,and good mechanical properties.A major disadvantage of alloying phosphorus in iron is the greater tool wear experienced with the using of ferro-phosphorous additives.Utilizing an experimental binder treatment process,a reduction in the strip and slide was observed during laboratory testing of both traditional binder treated premixes at sintered densities less than 7.0 g/cm3 and with warm die compaction materials at sintered densities of 7.2 g/cm3.This reduction in strip and slide has the potential to minimize die wear.Both the mechanical and magnetic properties of the new material will be presented.
