The technology, structure and properties of high-porous cellular heat-resistant materials

摘要

The peculiarities of the caking, themicrostructure and main properties of high-porouscellular heat-porous cellular heat-resistantmaterials produced by combined suspension-electrochemical method have been studied. Thedependencies of shrinkage at the caking andmicrostructure on the relative density and mean celldiameter of high-porous material have beenestablished. It has been shown that scale resistivityof high-porous cellular nihal and chromal ofsuspension-electrochemical formation surpasses onefor high-porous cellular materials from nichrome.Maximal air long exploitation temperature is higherfor high-porous cellular nihal and chromal than for nichrome.
