摘要

利用消失模铸造工艺制备了TiC

增强高铬铸铁复合材料

用SEM、EDS检测及能谱分析等手段进行检测

以某渣浆泵后护板为对象

研究了TiCp粒度对TiC

/Fe复合材料组织均匀性的影响。结果表明

随着颗粒度减小

颗粒经过气隙获得的运动速度越大

分布越均匀。相同粒度的复合材料后护板中部两侧标准偏差最小

均匀性最好。随着颗粒度的减小

标准偏差依次减小

最小为1.05。TiC

粒度为2 000目时

后护板组织均匀性最好

此时颗粒会发生分解。

Abstract

The TiC particle reinforced high chromium cast iron matrix composites were prepared by the lost foam casting process.Effects of the particle size on TiC

/Fe composite uniformity in a slurry pump back guard were investigated by SEM

EDS and energy spectrum analysis.The results show that with the particle size decreases

thmovement speed of the particles obtained through the air gap is increased and the distribution is more uniformThe uniformity is desirable of the composite castings of minimum standard deviation of the two sides at the samparticle size.The standard deviation of the composites is decreased with the particle size decreased to a minimum of 1.05.When the TiC particle size is 2 000 mesh

the rear panel has the satisfied uniformity

and the particles ardecomposed.
