摘要

研究了新型Al-Ti-C中间合金的制备方法。电弧高温能使Al与C更好地熔合

解决了Al与C润湿性差的问题。利用SEM、XRD、EDS对制备的Al-Ti-C中间合金进行分析。结果表明

电弧高温下制备的Al-Ti-C中间合金由Al、TiAl

和TiC组成。经过HF酸处理的石墨、钛粉在电流为75A

铝液温度为800℃条件下与纯铝反应

制备出效果最好的AlTi-C中间合金。

Abstract

A new method to prepare Al-Ti-C master alloy was proposed.Arc temperature can make graphite and aluminum better mix together

which can resolve the problems of poor wettability between graphite and aluminum.By using scanning electron microscopy（SEM）

X ray diffraction（XRD）

energy spectrum analysis（EDS）

Al-Ti-C master alloy prepared was analyzed.It can be seen that Al-Ti-C master alloy prepared by high temperature arc in pure molten aluminum is composed of Al

TiAl

and TiC.The Al-Ti-C master alloy with desirable effects was prepared by reaction of carbon and titanium with aluminum under current of 75 Aand molten aluminum temperature of 800 ℃.
