The tribology of electric vehicles
Jeanna Van Rensselar, Senior Feature Writer | TLT TLT Cover Story January 2019
Electric vehicles (EVs) are not new. They are as old as automobiles. According to STLE Fellow and Past President Dr. Edward Becker, P.E., president of Friction & Wear Solutions, LLC, in Brighton, Mich., electric vehicles outnumbered gasoline-powered vehicles in the U.S. before 1900. However, development of the modern electric vehicle began in earnest around 1990 as rising petroleum prices, stricter environmental regulations and increasing fuel economy standards put pressure on automakers to investigate other forms of propulsion, including alternative fuels and EVs.

Self-healing through carbon fixing material
Dr. Neil Canter, Contributing Editor | TLT Tech Beat January 2019
Today’s high-performance materials are expected to maintain optimum performance under increasingly severe operating conditions that may involve temperature and pressure extremes (high and low) and are in locations (such as wind turbines) that are difficult to access. But these environments can cause materials to break down through such phenomena as corrosion and wear. Read Full Article

Theoretical Solutions for Dynamic Characteristic of Spiral-Grooved Liquid Seals
By Lulu Zhai, Zuchao Zhu, Zhenjie Zhang, Jia Guo, & Baoling Cui
Annular seals represent one of the solutions for controlling leakage in high-speed turbomachinery, especially in multistage centrifugal pumps. In this article, a theoretical analysis method for leakage rate and dynamic characteristics of spiral-grooved liquid seals based on the theory of Iwatsubo and Childs is proposed.

Superlubricity-near zero friction from nanodiamonds with Anirudha Sumant with Argonne National Laboratory
Argonne National Laboratory has discovered a 2-D material that in certain conditions creates near zero friction. This new material may render oil useless as a lubricant and is poised to be a game changer in almost every industry. Dr. Anirudha Sumant is a materials scientist at the Center for Nanoscale Materials at Argonne National Laboratory, a U.S. Department of Energy facility. He is a leading expert on energy-efficient systems based on nanocarbon materials. His work on superlubricity—near zero friction—has opened a new era in solid lubrication technology.

2019 Keynote Address will explore Racing into the Future – Impact of Tribology on Vehicle Electrification
Electric mobility is quickly moving from someday to today as electric cars are becoming common, and even electric scooters and bikes are entering the mobility scene. The benefits of electrification are many, including reduced emissions and maintenance, and improved performance. It is also unsettling to many engineers who have spent a career enabling conventional engines and transmissions. While the needs of electric powertrains are different, the fundamentals are the same. We have been learning about those needs on the racetrack, through Formula E, as
well as in conventional automotive powertrains. This talk will share some of these lessons and point the way of future tribology efforts.
The 2019 keynote address will be presented by Jeff Hemphill, Chief Technical Officer, Americas, with Schaeffler Group USA Inc. Join Jeff and STLE we explore the future of electric vehicles.

Call for Tribology Experiments: STLE STEM Camp Program
STLE is inviting members and their organizations to submit ideas and materials for hands-on experiments focused on important areas of research within the fields of tribology and lubrication engineering for the Society’s 7th Annual Tribology STEM Camp to be held as part of the 74th STLE Annual Meeting & Exhibition at the Omni Nashville Hotel in Nashville, Tennessee, May 19-23, 2019.
STLE’s goal is to introduce high school students, who have an interest in STEM (science, technology, engineering and mathematics), to career opportunities in tribology and lubrication engineering. If you are interested in participating in the program or want more information, contact Karl Phipps at
, or provide suggestions for experiments by completing the
STEM Camp Experiment Application form
and submit by Jan. 18, 2019.
