Introduction
Over a fourteen-year period Wedeven Associates, Inc. has participated in highly challenging R&D tribology projects in aerospace and other industries. The practical knowledge gained, along with the testing capability developed, has resulted in a unique approach to tribology development. Tribology is taught from a systems perspective - "Systematic Tribology". A one or two-day courses on this subject are periodically given at Wedeven Associates, Inc. For information and enrollment in the next course, please contact the company. The Systematic Tribology course is also given off site at customer locations.



Overview
This course teaches a systematic approach to the development and application of tribology technology, which has been developed through activities supporting aerospace, industrial and automotive industries. Complex tribology phenomena are reduced to easy-to-understand concepts for engineering application. This course explains lubrication and failure mechanisms controlling performance and it illustrates methods to assemble material and lubricant technologies for component function. An understanding of tribology as a system allows a functional integration of tribology technologies for the 21st century.
