摘要

研究了电磁场作用下

氧化物陶瓷铸型的种类、粒度和保温功率对Ti50Al合金试样表面粗糙度的影响规律

分析了电磁场作用下表面粗糙度的形成机理。结果表明

在电磁场作用下

在5种氧化物陶瓷材料中所得Ti50Al合金试样的表面粗糙度大小依次为

Ra（Y2O3）<Ra[ZrO2（Y2O3）]<Ra[ZrO2（CaO）]<Ra（CaO）<Ra（Al2O3）;Ti50Al合金试样的表面粗糙度随着耐火材料粒度和保温功率的减小而降低。

Abstract

The effects of the types of oxide ceramic moulds and particles size of oxide ceramics as well as heating power on surface roughness of Ti50Al alloy specimens were examined in the condition of electromagnetic field

and the formation mechanism of surface roughness was approached.It is found that under electromagnetic filed

the orders of surface roughness of Ti50Al alloys prepared in five kinds of ceramic moulds are as follows:Ra（Al2O3）>Ra（CaO）>Ra（ZrO2

CaO）>Ra（ZrO2

Y2O3）>Ra（Y2O3）.Meanwhile

the surface roughness of Ti50Al alloy specimens is declined with decreasing in particle size of refractory and heating power.
