الوصف:
Turbine compressor coatings are evaluated for use in acidified environments. In such environments, field performance shows poor correlation to results of neutral salt spray tests (ASTM B117). Tests which might better describe these low pH atmospheres are described and the copper accelerated acetic acid salt spray (ASTM B368) is selected as the most useful development tool. In addition, combining CASS exposure with thermal cycling is shown to be a useful procedure to further differentiate coatings for use in acidic environments. It is shown that, unlike the neutral salt spray, in CASS, highly sacrificial (i.e., galvanic) aluminum-filled ceramic overlay coatings fail more rapidly than do non sacrificial materials. Conventional barrier films represented by high performance polymeric coatings are prone to severe blistering in these acidic conditions. Preferred acid resistant coatings are described.Copyright © 1986 by ASME
