Abstract

The problem of obtaining contrast in microphotographs of a scanning electron microscope between phases of the composite materials LSM ? YSZ and LSCF ? CGO is considered in the article. The method of the microstructure of the composite materials LSM ? YSZ including procedure of partial etching of the phase LSM is offered. The images analysis of microstructure allows to receive quantitative information on time and the phases which are parts of composite materials.
