Comparative study of synthesis of AA 7075ZrO ScienceDirect
The composite was produced by blending the AA 7075 with ZrO 2 contents of 2 and 5 wt.% in three different mills, as follows. (1) A Fritsch Pulverisette 5 planetary ball mill was operated at 120 rpm, employing stainless steel balls and vials, with the millingballtopowder weight ratio set at 8:1and 30 mL of methanol as the PCA (2) In the Simoloyer ball mill, two milling modes were employed.
