Abstract
Patente de Invenção: <B>"ELEMENTO DE AQUECIMENTO E PROCESSO PARA SUA FABRICAçãO"<D>. Para a fabricação de um elemento de aquecimento com alta taxa de aquecimento com um valor de resistência predeterminado para o disparo de sistemas de air bag, um corpo básico de cerâmica de oxido de alumínio é revestido com uma camada de vidro ou de cerâmica de vidro, em cuja superfície, que em caso de necessidade é brunida ou polida, é aplicado por processo de serigrafia uma camada de resinato de Au Pd, e em seguida estruturada com técnica de causticação para formar uma pista de resistência, que em seções possui contrações, sendo que as extremidades da pista de resistência contatadas depois em processo de serigrafia com uma pasta condutora de camada espessa de Ag Pd, cujo teor de Pd é decisivo para o valor de resistência requerido. Depois de secar e de cozer a pasta condutora de camada espessa, o corpo de base, revestido deste modo, é submetido a um tratamento térmico com uma temperatura na faixa de 850 a 950°C durante tanto tempo até que o paládio é uniformemente distribuído na camada de resistência, e até que surge um valor de resistência estável. Depois, nas bordas viradas para a pista de resistência dos contatos de Ag Pd são dispostas barragens de parada de solda na forma de nervuras de vidro, para diminuir o risco da destruição da liga da pista de resistência num processo de solda seguinte.
