Wear Analysis of LM 25 (A356) Alloy Manufactured by Squeeze Casting

Abstract:

Historically, the series of LM were developed for high strength, corrosion resistance, and good machinability for many applications. LM 25 Al-7Si-0.3Mg-0.5Fe alloy cylindrical shaped castings were manufactured successfully by Squeeze Casting process at high temperature and high pressure. The casting products were made by addition of nanoparticles and without nanoparticles. Heat treatment process was conducted at 490^○C and metals was quenched at 30^○C (water).Specimens were prepared with and without squeeze and stirrer. Wear test was carried out by, variation in load, and microstructure also studied. The results were compared before and after the heat treatment process for addition of nanoparticle and without nanoparticle. SEM analysis was made on worn surface of the wear specimens for different conditions to study the influence of different casting on the wear behaviour mechanism of the cast alloys. Surface roughness was evaluated before and after the wear analysis for various conditions.
