(Michigan Metrology: Livonia, MI) -- The long-standing “Surface Texture and Tribology” short course, presented by Don Cohen, Ph.D. 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,” says Cohen, who presents the course. “The material goes beyond equations and instead focuses on how texture relates to component functions, such as friction, sealing, durability, and appearance. It’s designed for technicians, engineers, and scientists who address surface finish issues daily, but 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 material covering:
