Abrasive Wear of the Alsi12Mg With Al-Si Alloy for Casting Machine Parts

Abstract

This work present results modification AlSi12%Mg alloy with modifier contained Al and Si. It modifier was has taken down was with components Al, Al7%Si i Al12%Si. homogenous modifier obtained by fast cooling of homogenous modifiers at V=200C/s The components were put into a crucible containing liquid Al-Si alloy and kept there for one minute. The influence of modifier in reference to pulp of worked alloy on abrasive wear was introduced in graphic mould. The analysis modification process of hypo eutectic alloy AlSi12%Mg with compound modifier showed the modifying influence on structure and abrasive wear.
