摘要：

Results from studies on the modification of Nb-Cr-Mo-Si-B composites with Mo chalcogenides are presented. Use of MoS(2)and MoSe(2)as integral parts of multicomponent oxygen-free compositions was shown to have positive effects due to the formation of highly active elemental Mo species resulting from their dissociation that determined the high heat resistance of coatings formed from them.
