Design, construction, and initial results for an erosion-corrosion test system
Erosion and erosion-corrosion are among the most serious forms of material degradiation encountered in coal conversion and combustion systems. To improve our understanding of such phenomena, a unique system has been constructed to perform erosion and erosion-corrosion studies in a specially modified scanning electron microscope. This microscope incorporates a gun that shoots erosive particles at a target specimen and also a hot stage that can heat both the test specimen and a corrosive gas directed onto the specimen surface. Intial results show that the system is capable of novel studies or erosion and erosion-corrosion, which should lead to improved understanding of those degradation modes. 8 refs., 9 figs.
