The consequence of carbon deposition is a metal related degradation phenomenon known as "Metal dusting". Metal dusting results in rapid material wastage and/or thinning of material, producing hemispherical pits and grooves as the affected material diSintegrates into a mixture of carbon and metal particles. The aim of this study was to elucidate m terial factors that cause or contribute to metal dusting. This was achieved by refurbishing the in-built metal dusting rig to carry out experimental tests on a laboratory scale. The objectives of this research were to simulate a metal dusting enVironment, characterize the...
