Wear Properties on AA2014/Al 2 O 3 /TiB 2
Hybrid Metal Matrix Composites
Jayavelu Sundaram, J. Udaya Prakash, and Harivind Kagitha
Abstract Wear properties of aluminium hybrid metal matrix composites have been
analyzed in this study. The driving force behind this study is too broad a knowledge
base on aluminium powder metallurgy to provide ideas for making aluminium powder
components economical and wear-resistant. In this study, AA2014, AA2014 + Al 2 O 3
+ TiB 2 wear analysis was concentrated using pin-on disc tribotester. The samples
tested for wear were prepared using the powder metallurgy method. Wear tests were
carried out with loading conditions of 20 N under normal atmosphere at a sliding
velocity of 1.5 m/s. Coefficient of friction, specific wear rate and wear rate have been
calculated. AA2014 + 5 wt%–Al 2 O 3 + 5 wt%–TiB 2 has a lower rate of wear due to
the presence of wear resistance materials when compared with the AA2014 alloy.

1 Introduction
Today, the biggest problem of worn-out rotating and frictional parts due to wear is
faced by major industries. Wear is causing energy and natural resource shortages.
Because of traditional production methods and materials, there are a number of
significant amounts of wear-based research and development that have shown a lack
of significant improvements in wear resistance [1].
Powder metallurgy (P/M) has become a significant method for the processing
of metal parts, such as high efficiency in the production of net or near-net types
of medium to high size. P/M also has uniform characteristics: structures of fine
grain and chemical homogeneity. Current consumer goods have a growing number
