Abstract
Both uncoated and coated exposed panels were taken out after 18 m of exposure from sites. No appreciable changes were noted for coated panels exposed at all the sites. However, for coated and scribed panels a light attack of rust was visible along scribed lines. Rust product developed at all sites was brownish, loosely bound on MS and adherent brownish black on WS (Table 3.1). Uncoated panels had different pitting attack and WS exhibited less pitting marks than MS. The variation of pitting densities and distribution at different sites depended on the material and the environment prevalent at the site.
The results obtained from experiments as recorded in Chapter 3 are discussed in three parts viz. field tests, laboratory tests and simulation tests.
