Abstract

"MATERIAL DE ELETRODO INERTE EM FORMA PULVERIZADA NANOCRISTALINA". A invenção refere-se a um material de eletrodo inerte em forma pulverizada compreendendo partículas tendo um tamanho de partícula médio de 0,1 a 100<109>m e cada uma formada por um aglomerado de grãos de um material cerâmico e grãos de um metal ou liga com cada grão de material cerâmico compreendendo um nanocristal do material cerâmico e cada grão de metal ou liga compreendendo um nanocristal do metal ou liga. Alternativamente, cada partícula pode ser formada por um aglomerado de grãos com cada grão compreendendo um nanocristal de um material cerâmico de fase simples, um metal ou liga. O material de eletrodo em forma pulverizada de acordo com a invenção é útil para a fabricação de eletrodos inertes tendo aperfeiçoadas propriedades de resistência à corrosão e choque térmico."NANOCRISTALIN SPRAY INERT ELECTRODE MATERIAL". The invention relates to an inert powdered electrode material comprising particles having an average particle size of 0.1 to 100 µm and each formed by an agglomerate of grain of a ceramic material and grain of a metal or It alloys with each grain of ceramic material comprising one nanocrystal of ceramic material and each grain of metal or alloy comprising one nanocrystal of metal or alloy. Alternatively, each particle may be formed of a grain cluster with each grain comprising a nanocrystalline of a single phase ceramic material, a metal or alloy. The spray-shaped electrode material according to the invention is useful for the manufacture of inert electrodes having improved corrosion resistance and thermal shock properties.
