This study carrys out to determine the strength of oxide skins of Al alloy melts as the practical alloy for automobile piston. This has been observed by Rotational Die Movement Equiment for the temperature range from 600℃ to 750℃ and oxidation time range from 10min to 60min. This method was able to quantify the strength of oxide skins of the molten alloys and had ±3% experimence error range. This strength of oxide skins of the molten alloys were much more affected by oxidation temperature than oxidation time.

This study was earned out to determine the strength of oxide skins of Al-10Si alloy melts and survey the effects of adding Mg. Cu. Ni and 1Cu-0.5Mg-2Ni as the practical alloy for automobile piston. This has been observed by Rotational Die Movement equipment for the temperature range from 600℃ to over ℃ and the oxidation time range from 10min. to 60min. and strength of oxide skins of the molten alloys were much more affected by oxidation temperature than oxidation time. Mg element was also more affected than any other elements. However, the effect of adding 1Cu-0.5Mg-2Ni alloy was located in the middle of alloy which had added Mg and which had added Cu and Ni.<br/>
