The long-standing Surface Texture and Tribology short course, presented by Dr. Don Cohen of Michigan Metrology, is now available as individual modules on the udemy.com learning website. The online format allows students to choose the course segments that are pertinent to their work, and to learn at their own pace and schedule.
“This online, modular format makes learning about surface roughness, finish, friction and wear more affordable and accessible,” said Dr. Cohen, who presents the course. “The material goes beyond equations and instead focuses on how texture relates to component functions such as sealing, durability and appearance. It’s designed for technicians, engineers and scientists who address surface finish issues daily, yet because it’s modular it is approachable for anyone who wants to understand surface interactions.”
The course modules range in length from 45 minutes to 2 hours, including:
- Surface Finish: Introduction, Instruments & Correlation
- Filtering for Roughness Waviness and Form
- Surface Roughness Parameters
- Wear Mechanisms, Measurement and Specification
- Dry, Sliding Friction
- Lubricated Friction
- Rolling Friction
- Surface Energy, Wetting and Surface Roughness
- Seals, Sealing and Surface Finish
- Coatings: Surface Roughness from Substrate to Topcoat.
“We have been providing training in surface metrology and tribology for over fifteen years,” said Dr. Cohen. “This class makes nearly 16 hours of training available to students, and it’s available for learning at the pace that’s best for retaining the information.”

About the Instructor, Dr. Donald Cohen
Dr. Cohen established Michigan Metrology In 1994 to help engineers and scientists solve problems related to, “squeaks, leaks, friction, wear, appearance, adhesion and other issues,” using 3D surface texture measurement and analysis.
Prior to forming Michigan Metrology, Dr. Cohen was V.P. of Engineering at WYKO Corporation (now part of Bruker Corporation), developing surface metrology instrumentation. He served as Vice Chairman/Chairman of the ANSI/ASME B46.1 Surface Texture Standards committee from 2000-2011 and is past Chairman of the STLE-Detroit section. He holds a B.S. / M.S. in Physics and a Ph.D. in Optical Sciences.
