Non-destructive Testing Services
The Non-Destructive Testing and Evaluation (NDT&E) laboratory utilizes radiography and other approaches to assist clients in obtaining quality assurance.
Testing results in the realization of such manufacturing goals as improved quality through flaw detection, rejection of substandard materials before finishing, establishment of standards, the elimination or minimization of costly failures, and the improvement of design integrity. These techniques are also employed to determine if test specimens are representative of the material or structure and to indicate anomalous areas prior to testing.
Capabilities
- X-Rays to 06V to 320kV
- Scanning Electron Microscope (SEM) – Resolution to 300,000 x magnification
- Energy Dispersive Spectroscopy (EDS) – Surface Elemental Analysis
- Olympus PME metallograph with photographic capabilities
- Olympus stereo microscope with digital imagery
This laboratory also conducts macroscopic and microscopic examinations of materials and structures. These studies are used to assist with design problems in the development of unique composite structures and to aid in the interpretation of test and/or performance data.
