Silicon nitride sealing rings with diamond coating

Products InternationalNational

Silva, Rui; Fernandes, António; Amaral, Margarida ; Almeida, Flávia; Oliveira, Filipe ; Costa, Florinda; Carrapichano, João

The present invention refers to a dynamic mechanical sealing system comprising rings manufactured by means of coating silicon nitride ceramic pieces (Si3N4) with diamond films obtained by Chemical Vapour Deposition (CVD). The said mechanical elements should simultaneously warrant low friction, wear-resistance and good sealant properties...
