查询词典 tubular surface

The wall of the burning chamber was pitted at the beginning then gradually burnt through.By means of the Bunsen burner,tubular furnace and XRD,SEM,EDS,this special type of high-temperabure destruction was studied.It was found that the phenomenon is resulted from the combined action of CO and lower hydrocarbon on Ni-Cr alloy.Firstly,Ni-Cr alloy is carbonized and selectively oxidized by CO to produce Cr2C,Cr3C2 and Ni-Cr2O3,while the capillary cracks in the surface layer are formed simultaneously.
