Development of new high temperature metallic coating materials

Abstract: 

Flaring natural gas is a routine practice in the course of oil production. This study presents two parts .The first one is presenting analyses of corrosion damage experienced by a plasma-sprayed coating of SS310 alloy, after exposure to a simulated flare tip environment at 975 oC. Samples made of SS310 were utilized to evaluate a proposed coating system, which consists of top coat with yttria stabilized zirconia and a bond coat of Co32Ni21Cr8Al0Y.A simulated gas composition of a flare tip environment was suggested as;CO2 5% :SO2 9.58%:H2O 3.59% :N2 81.83%. The second part of this study is focused on a practical methodology for synthesis SrA1l2O19 as promising material for high temperature thermal barrier coating (TBC) through simple self combustion (organic acid thermal dissociation) routes.
