During the second quarterly period of the program, further work was carried out on two experimental techniques using the plasma torch heat source. The test technique which exposes the bore of a tubular specimen to a high heat flux and a high velocity of selected gas mixtures was instrumented and operating conditions were studied. The technique was improved as a means of studying chemical reactions. Additional tubular specimens of refractory carbides are in preparation by Carborundum. The plasma torch impingement test method was used to obtain data for Graphitite GX specimens comparable to data published previously for other graphites. Author
