SPRAYING MATERIAL FOR HOT OR PLASMA SPRAYING AND A PROCESS OF ITS PRODUCTION

摘要

Spraying material for hot or plasma spraying consisting of several metal oxides from which at least one oxide is a glass-forming oxide characterized by that it is formed by agglomerates of at least two fundamental oxides, especially Al2O3, MgO, CaO, BaO, Cr2O3, TiO2 or ZrO2 in the amount 50 to 99 % by weight and by at least one glass-forming oxide with the melting point lower about 50 to 1100.degree.C than the melting points of fundamental oxides, especially SiO2, in the amount 1 to 50 % by weight. And a process for the production of such a spraying material.
