Abstract

LM25 aluminum alloys are extensively used to produce castings with superior mechanical properties. It is, in
practice, the general purpose high strength casting alloy which exhibits fair resistance to corrosion. Its potential
uses are increased by its availability of various conditions of heat treatment in both sand and chill castings.
Consequently, LM25 finds application in the food, chemical, marine, electrical, and many other industries and above
all in road transport vehicles where it is used for cylinder blocks and heads and other engine and body castings.
Even thin castings can be produced which are leak tight and free from hot tearing. Hence, this investigation makes
an attempt to analyze the dry and wet sliding wear behavior of squeeze cast LM25 aluminum alloy for the varying
load, speed, and sliding distances. Further, to determine the effect of each input parameter on the wear rate,
ANOVA analysis using Minitab - 17 is carried out. Microstructural studies were carried out to analyze patterns of
wear mechanisms on the worn surfaces using an optical microscope and scanning electron microscope.
