METHOD FOR EVALUATION OF LEVEL OF POLLUTION BETWEEN STEEL GRAINS WITH FILM INSULATIONS

摘要

Method for evaluation of level of pollution between steel grains with film insulations through analysis of surface of inter-grain destruction by means of transmission electronic microscopy with simultaneous X-ray micro-analysis of insulations extracted with coal extraction replicas at which one observes up to 400 fields of vision at magnification 2000 times. Dimension of cell of grid-sublayer is arranged as square with side 50 mkm.
