Tribology & Wear

Oiled GearsTribology is the study of friction, wear and lubrication as observed in a system.  Any time two surfaces slide past one another in intimate contact friction will be created and wear will occur.  Since every engineering system is subject to wear, significant research has been conducted to minimize its effect.  Wear behavior is assessed by stress analysis, material properties and surface geometry.  Lubricants to prevent wear vary widely and must be matched to the system they are intended to help.

We have solved hundreds of tribological challenges using a systematic approach:

  • Complete analysis of current system’s materials and contact stresses
  • Evaluation of wear surface to determine active wear mode
  • Review of lubricant properties and behavior (if applicable)
  • Wear testing from small to large scale; we can design the appropriate wear test for you
  • Comprehensive report highlighting the areas needing improvement and proposed work, including budget

“We have worked with numerous expert witnesses, but Dr. Niebuhr is heads above the competition for his focus on details and his ability to explain abstract concepts in everyday vernacular.”

Jeff Temple

Product Liability Attorney

After an employee was severely injured by an escaped liquid, we hired NME to determine the cause and origin of the leakage and what break down in procedures may have occurred to allow this accident. We were very impressed by Dr. Niebuhr’s level of professionalism, attention to detail and clear explanation of the issues at hand. I would hire his firm again in the future.”
