Abstract

Results are reported from studies in which several monolithic ceramic materials in the form of modulus-of-rupture bars were exposed for 100 h to the combustion conditions found in either a small single- or two-cylinder diesel engine. Fuels included a standard Phillips D-2 diesel or synthetic mixture of the Phillips D-2 and an aromatic blend. Tbe ceramics included two commercial grades of partially stabilized zirconia (PSZ-TS and PSZ-MS), silicon nitride (GTE WESGO SNW-1000 and Norton NT-154), and (Hexoloy SA) silicon carbide. Results are presented from postexposure fourpoint bend rupture tests conducted at either room temperature or 700°C. Partially stabilized zirconia TS grade showed considerable reduction while the other materials showed only a slight or no change in rupture strength.
