Materials Science Seminar Series – Mr. William J. Lenling

September 28, 2023 @ 4:00 PM 5:00 PM

Materials Science Seminar Series presents Mr. William J. Lenling on Thursday, September 28, from 4 to 5 p.m. The seminar is hosted by Professor John Perepezko and will be held in MS&E building room 265. Mr. William Lenling will be discussing Surface Engineering with the Technologies of Thermal Spray and Material Science and Engineering.


The technologies of thermal spray and a good understanding of the properties of metals, metal alloys, and several ceramics are used to engineer surfaces on a wide variety of components. This combination has been used to produce surface engineering solutions in many industries. Thermal spray coatings are used to create critical surfaces for components in jet engines, medical devices, food processing, agriculture, recreational, renewable energy, oil & gas and many other industries. This presentation will describe the processes of thermal spray and several examples of how the technologies are used to provide critical surface properties on many components. The talk will also discuss how heat treating of some coating types can greatly enhance the coatings adhesion and microstructure.


Bill is a co-founder (1992), of TST Engineered Coatings, in Sun Prairie, Wisconsin, which engineers and manufactures industrial coatings and coated components. His work has resulted in many technical achievements that initiated in laboratory scale studies, and then organized the resources to bring about commercial success.

These include solderable coatings for high powered circuit boards, dielectric materials for electrosurgical instruments, improved wear resistance for food processing components, metallurgically bonded wear resistant coating technology for construction, agriculture and oil & gas components, and high-volume thermal spray manufacturing techniques. The developed coating solutions have been used in many industries including medical, food processing, agriculture, construction, energy, marine, automotive, aerospace and others. His work has helped TST become a leading company in thermal spray innovation.

Prior to his current activities at TST, he worked at Fisher Barton, Inc. of Watertown, WI, where he spent fifteen months at Sandia National Labs performing thermal spray research. He has published several technical papers and has a variety of patents.

He has participated in and chaired many ASM Thermal Spray Society (TSS) committees and is the current Past President of the TSS Board. He has also been on various ASM committees and is a past trustee of the ASM Board. In 2012 he became an ASM Fellow. In 2018 he was inducted into the ASM Thermal Spray Society Hall of Fame.

He received a B.S. and M.S. in Metallurgical Engineering from the University of Wisconsin-Madison (1985 and 1986). The University of Wisconsin-Madison College of Engineering awarded him the Distinguished Achievement Award in 2009.
