Abstract

Patente de Invenção:<B>"PROCESSO PARA PRODUçãO DE COMPOSTOS DE MATERIAIS BIDIMENSIONAIS"<D>. A invenção refere-se a um processo para produção de compostos de materiais bidimensionais de um material de suporte e pelo menos uma camada de pó eletricamente condutora prevista ou, eventualmente, compacta sobre o mesmo ou de um pó eletricamente condutor, que é compactada para um corpo moldado de pó bidimensional, sendo que o material de suporte e a camada de pó ou o corpo moldado de pó é exposto, por um tempo curto, a um campo alternando magnético, na faixa de freq³ência de aproximadamente 10 kHz, para gerar na camada de pó ou no corpo moldado de pó uma corrente de indução de uma densidade de energia tal que os pontos de contato das partículas de pó entre si e, na existência de um material de suporte, também seus pontos de contato com o material de suporte, a uma temperatura acima da temperatura de sinterização, tornam-se líquidas por fusão e são soldadas.
