Penn research shows mechanism behind wear at the atomic scale
Date:1/30/2013

es and tools for nanomanufacturing.

The math behind the atomic attrition mechanism could eventually be applied in a fundamental way.

"The goal of this avenue of research is to get to the point where you tell me the materials in contact, and you tell me the period they are in contact and the stresses applied and I will be able to tell you the rate at which atoms will be removed," Jacobs said.

"With a fundamental understanding of wear, you can cleverly design surfaces and choose materials to make longer lasting devices," Carpick said.

This fundamental, predicative understanding of wear could vastly improve nanomechanical design, increasing functionality and decreasing costs.
