Press Release: 

MOLYKOTE® expert to discuss wear scar measurement in anti-friction coatings 

Molykote® specialty lubricants

Measurement methods that yield lowest standard deviation and largest detectable change to be discussed


MIDLAND, MI. May 12, 2021 – DuPont (NYSE:DD) today announced that MOLYKOTE® Specialty Lubricants Product R&D Chemist Melissa Mushrush, Ph.D., will present “Statistical Considerations for Wear Scar Measurement in Antifriction Coatings” at the Society of Tribologists and Lubrication Engineers (STLE) Virtual Annual Meeting & Exhibition, May 17 through 20.

“When testing anti-friction coatings, perhaps the most difficult aspect to quantify reproducibly is the measurement of the resulting wear scar after a tribological test has been conducted,” Mushrush said.

Common methods used to measure the thickness of the film and the depth of the wear scar generally require the user to assess the planes of the film surface and the bottom of the wear scar, introducing inherent variability into the measurement.

In her presentation, Mushrush will assess various film thickness and wear scar depth, width and volume measurements to determine which methods offer the lowest standard deviation in a statistically significant set of measurements. She also will examine the largest change that can be detected when using the methods with the lowest standard deviation.

Mushrush’s presentation is part of Technical Session 6E – Wear II and will take place from 5 to 5:30 p.m. on Wednesday, May 19, in Virtual Meeting Room 5.
