Abstract A research program has been carried out in which a new instantaneous atmospheric corrosion rate monitor (ACRM) has been developed and evaluated, and equipment has been constructed which will allow the use of many sensors in an economical way in outdoor exposures. In the first task, the ACRM was developed and tested in flow chambers in which relative humidity and gaseous and particulate pollutant levels can be controlled. Diurnal cycles and periods of rain have been simulated. The effects of aerosols have been studied. A computerized system was used for collection, storage, and analysis of the electrochemical data. In the second task, a relatively inexpensive electronics system for control of the ACRM and measurement of atmospheric corrosion rates which was designed and built under a subcontract at Portland State University was tested. In the third task, calibration of deterioration rates of various metallic and nonmetallic materials with the response of the ACRMs attached to these materials was carried out under controlled environmental conditions using the system developed in the second task. A Quality Assurance project plan has been prepared with inputs from the Rockwell International Environmental Monitoring and Service Center and Quality Assurance System audits have been performed.
