Abstract

"MéTODO DE FABRICAçãO DA VELA DE IGNIçãO". A presente invenção refere-se à vela de ignição (100) utilizada para ignição de motores de combustão interna como o de automóvel e seu método de fabricação. No estado da técnica, a maioria das velas de ignição (100) largamente utilizadas provê a superfície do isolador (2) dotada de camada vitrificada (2d), basicamente para dirimir fenómeno de descarga disruptiva, flash over, além de apresentar a função como manutenção da superfície do isolador com lisura, livre de incrustações, bem como elevar-lhe as resistências química e mecânica. A presente invenção diz respeito ao fornecimento do método de fabricação, preparação, elaboração dos componentes na formação da camada vitrificada (2d), adicionando-se os ligantes que obstam eluição dos componentes solúveis na barbotina do vitrificante capaz de dirimir sua elevação da viscosidade lesiva ao processo de fabricação da vela de ignição cuja superfície do isolador vitrificada (2d) está isenta ou íntima presença de chumbo, proporciona-lhe ótima resistência à descarga disruptiva, ou seja, sem afetar-lhe a qualidade inerente ao bom desempenho.
