A standard carburization test method has been developed that will allow investigators to generate carburization data under uniform, repeatable test parameters and procedures. Test results are discussed with particular reference to test parameters and procedures, as well as the methods of sample evaluation.
In order to simplify the measurement of electrochemical noise in field applications, three identical electrodes, one acting as reference electrode (RE), are often used. In this work, a measurement scheme, which employs two REs is proposed, which can reduce the error due to the RE's noise. An example of its implementation is also presented.
New high-solids coatings are sometimes required to meet volatile organic compound (VOC) legislation. Lack of data on same needs accelerated test methods to evaluate performance. The test method must: • Be performed using commercially available equipment • Take a relatively short time period. • Correlate with real life exposure.
