Grazing-Angle Fourier Transform Infrared Spectroscopy for Surface Cleanliness Verification
Abstract
As part of the Surface Cleanliness Verification project, sponsored by the Strategic Environmental Research and Development Program, the Naval Facilities Engineering Service Center conducted an investigation of grazing-angle reflectance Fourier Transform Infrared (FTIR) Spectroscopy as a tool for online cleanliness verification at DOD maintenance and repair facilities. In the project's first year, the feasibility of grazing-angle reflectance FTIR was demonstrated in the laboratory for the detection of organic contaminant residues on reflective surfaces. In Years 2 and 3 this technology was transitioned from the laboratory into a portable field device capable of detecting organic and certain inorganic contaminants on reflective surfaces at very sensitive levels (< 1.0 microgram/sq cm). Examples of DoD applications where surface cleanliness is critical include coating, plating and bonding of aircraft parts; beaming refurbishment; and shipboard surface tile mounting. Visual inspection and water break testing are often inadequate to detect contamination that may cause subsequent bonding or fouling problems if not removed.
