Abstract

resumo “métodos de reparo de defeitos em um núcleo cerâmico e núcleo cerâmico” fornece-se um método para reparo de defeitos em um núcleo cerâmico adaptado para uso em um processo de fundição. o núcleo cerâmico é formado a partir de uma pasta semifluida que compreende pelo menos um material de pó refratário suspenso em um veículo líquido. o método inclui formar uma mistura de reparo que compreende um diluente líquido e o pelo menos um material de pó refratário suspenso no veículo líquido da pasta semifluida. a mistura de reparo é aplicada a uma região do núcleo cerâmico que inclui pelo menos um defeito e então, o núcleo cerâmico é submetido à inflamação para queimar o veículo líquido na mistura de reparo e formar uma composição cerâmica que fecha o defeito.abstract “methods of repairing defects in a ceramic core and ceramic core” a method for repairing defects in a ceramic core adapted for use in a casting process is provided. the ceramic core is formed from a slurry comprising at least one refractory powder material suspended in a liquid carrier. the method includes forming a repair mixture comprising a liquid diluent and the at least one refractory powder material suspended in the liquid carrier of the slurry. the repair mixture is applied to a region of the ceramic core that includes at least one defect, and then the ceramic core is ignited to burn the liquid vehicle in the repair mixture and form a ceramic composition that closes the defect.
