Abstract
review has been conducted of burner rigs and their use in the development of hot corrosion resistant materials for marine gas turbine engines. Rig tests, in the evaluation of materials, are usually regarded as an intermediate stage between laboratory tests and engine tests. Rig running costs are so much more economical than those of engines that if the rig results are valid, there is an overwhelming argument for using them. Qualitative correlation among rigs is good but there is lack, of agreement in quantitative results. The present criterion for choice of rigs is their ability to duplicate the corrosion morphologies produced in gas turbine engines under operational modes of interest. Further progress could be made by better reporting of the rig environment.
