The Influence of High Energy Ball Milling on the Morphology of Metal-Ceramic Composite Powders
Abstract:
Investigations of high energy milling parameter of aluminum or siluminum based materials with ceramic particles has been conducted. Work consists of two parts. In the first part two types of composite powders with the same metal-ceramic ratio were synthesized via planetary ball milling with the same milling parameters. After SEM studies it has been shown, that despite of materials similarities significantly different milling times have been required for manufacturing fine grained powders. Planetary ball milling of the chosen aluminum matrix composite performed in two different milling cycles was the second part of the experiment. Two different times of the break between the consecutive millings were applied. It has been found that increase of the time of the break led to the finer powder after milling.
