摘要

本实验表明

用ZL108铝硅合金生产活塞

适当控制镁含量

只经T

处理

就可达到国家对铝活塞规定的指标

可取消钠盐变质工序。同时

就镁对钠盐变质的影响和钠盐变质的应用

提出新的看法。

Abstract

In this paper

we evaluated the influence of magnesium addition on the effect of modification and tested whether the modifying process was necessary or not. It was found that the properties of pistons casting with no modifying melts were satisfying

as long as the magnesium content in alloy was controlled and the pistons were heat-treated in Te condition. Without modifying process

economical benefit was increased

working condition was improved and environmental contamination was decreased
