        Dr. Zoheir Farhat earned a PhD degree in Materials Engineering from the University of Windsor, Windsor, Ontario, Canada in 1996 in the fabrication and tribological behaviour of nano-laminated composite coatings. After receiving his PhD he held many positions in academia, industry and government research laboratories. In 2005, Dr. Farhat joined Dalhousie University as an Assistant Professor and was promoted to Associate Professor and appointed as the Chair of the Materials Engineering Program in 2007. Dr. Farhat is also the founder and Group Leader of the Advanced Tribology Laboratory (ATL) and a member of the Institute of Research in Materials (IRM) at Dalhousie University. He is a former Chair of the "Materials Integrity and Performance" section of the Metallurgical Society (MetSoc) of the Canadian Institute of Mining, Metallurgy & Petroleum (CIM) and a former member of the Board of Directors of MetSoc. He has 25 years of experience in the field of wear of materials. To-date his lifetime research has resulted in over 60 journal papers and conference contributions and over 40 industrial consulting reports. His work is published in some of the most prestigious international journals in the field. In just the past 5 years, he managed to attract over $2.5M of research funds and trained 39 graduate students (MASc, PhD), postdocs, senior undergrad students and research engineers. He has established many national and international collaborations with industry and academia. He has organized and Chaired symposia on the Corrosion and Wear of Materials. Dr. Farhat is an active member of many professional societies and a former member of the board of review and key reader in Metallurgical and Materials Transactions A, TMS. He also served as a reviewer for many international journals and funding agencies.

Sample of Current Research Activities

(a) Wear and Dent Resistance of Superelastic TiNi Bearings for Aerospace Applications

    While superelastic TiNi alloys have been around for a while, they have not been fully exploited for tribological applications. Dr. Farhat's work is directed towards understanding the wear and dent behaviour of these unique materials for use in tribological applications. One potential application of these alloys is in high precision bearings for the aerospace industry. Superelastic bearings are expected to absorb the high impact loads experienced during space vehicles and aircrafts landing and take off. Dr. Farhat's work in this area has attracted the attention of researchers in NASA Glen Research Center and led to an ongoing collaboration that focuses on extending the use of superelastic materials to bearings in aerospace applications. Dr. Farhat discovered the existence of a strong relationship between loading rate and superelasticity under localized "indentation" loading. The implication of the dependency of superelasticity on indentation loading rate and the limitations this behaviour imposes on the use of these alloys is being fully examined.

(b) Wear of Automotive Al-based Alloys

    The research focuses on understanding and improving the wear resistance of light weight automotive Al-based alloys and developing novel surface treatment to protect lightweight materials’ surfaces against wear. Dr. Farhat’s work in this area was performed in close collaboration with two leading companies in their fields, Vector Aerospace and Magna-PFC International. The work has resulted in the adaptation of pulsating high pressure waterjet as a new surface treatment process. This cost effective process can be applied locally to cast automotive components to enhance their surface tribological properties. The treatment resulted in 60% enhancement in wear resistance while only 15% improvement in wear resistance was achieved using hot isostatic pressing.
