In the present paper the problems, connected with the formation of a powder material and its surface layers in conditions of chemical thermal treatment and impregnation with melt, combined with the use of mechanical loads at different process stages are examined. The new results of liquid phase influence on compaction of powder preforms, subjected to impregnation, are obtained. The presence of a liquid phase in preform surface layers can also be connected with the change of the materials chemical composition as the result of boronizing, siliconizing or other kinds of chemical thermal treatment
