The Surface Roughness, Texture and Tribology, presented by Dr. Donald Cohen, is now offered as a single course with over eleven hours of content, and as individual course modules that allow students to tailor the material for their particular needs.

“The online format is a highly affordable way to learn about surface texture and surface interactions,” said Dr. Cohen. “We’ve now made the entire course available for students who want to take a deep dive into this material. For students who may need to focus their learning time, or who want to explore particular areas of the field, the individual course modules are a very cost-effective option as well.”

The course material is designed for technicians, engineers, students, and scientists working in fields such as aerospace, automotive, materials, medical devices, and others where surface texture, friction, or wear play important roles.. The ten course modules range in length from 45 minutes to two hours, including material covering:

  • 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.

“This course goes far beyond the equations and math of analyzing surface texture,” said Dr. Cohen. “We focus instead on how texture relates to how components function, relating it to friction, sealing, durability, noise, appearance, and so on.”

The Surface Roughness, Texture and Tribology course is available online at udemy.com. The course is also offered live, in-person several times per year, and as a customized training for individual companies.
