Testing of Metallic and Inorganic Coatings


Book Description

Coatings are tested to confirm compliance with specifications, to monitor the operation of a coating process, and to evaluate coatings for various services. The ability of a coating to perform as intended usually depends on several characteristics, and the testing of a coating usually involves several different tests. At first glance the nature of a characteristic that is being tested may seem clear and the results of a test may seem to be unambiguous, however, the nature of a characteristic my be more complex than realized and the ability of a test to measure the characteristic may be less than expected. The members of the ASTM Committee B-8 on Metallic and Inorganic Coatings felt it was desirable to organize a symposium on the testing of the metallic and inorganic coatings so as to bring these problems to the attention of practitioners. This publication is based on the symposium, which was presented in Chicago on April 14 and 15, 1986.

Corrosion Testing of Materials with Metallic and Inorganic Coatings


Book Description

Corrosion resistance is an important characteristic of many types of metallic and inorganic coating systems. Corrosion resistance of coatings usually involves appearance maintenance as well as protection from structural damage. Corrosion tests have been an important approach for evaluating the type and extent of damage that occurs to coated products. Corrosion tests have been used both to assure the quality and performance of coated parts and to simulate the degree of degradation that occurs to components when exposed to specific atmospheric conditions for an extended time. The standard tests that have been developed for both of these purposes are described, and some of the problems with the testing approach are reviewed. In particular, the problem of simulating and accelerating atmospheric corrosion in a laboratory environment is highlighted. Some of the newer approaches to corrosion testing using electrochemical techniques are discussed. These approaches may have merit, but many problems remain to be solved.
