DTIC ADA125512: Wear Particle Atlas. Revised

The Wear Particles Atlas (Revised) is a guide to wear particle identification containing photographs of typical wear particles found in used lubricating oil, illustrative case histories, and operational procedures for wear debris analysis. Wear particle analysis supports identification of wear modes within a machine based on the quantity, morphology, and composition of particles present in a representative lubricant sample. Photomicrographs in this document facilitate technology transfer to the neophyte and act as a guide to the experienced analyst. Section 1.0 on Wear Particle Identification describes particle morphologies, distinguishes between ferrous and nonferrous materials, and illustrates typical particulate contamination. Section 2.0 Case Histories, shows the potential utility of wear debris analysis and the progression of thought that goes into an analysis. Section 3.0 Operational Procedures, details the methodologies used in wear debris analysis.
