Abstract
Per fabbricare un elemento di guarnizione, che è costituito da un corpo base (1) di materiale gommoso con un rivestimento (3) antiattrito, che presenta una alta flessibilità, viene previsto un procedimento di fabbricazione secondo cui il rivestimento (3) è costituito da un copolimero di etilene - clortrifluoroetilene, che nell'ambito di un procedimento di sinterizzazione viene posto sulla superficie parziale (2) del corpo base (1) e viene unito ad esso. Il punto di partenza è lo stato di polvere del materiale di rivestimento, che viene riscaldato fino a temperature di 300 gradi centigradi, trasformato in stato fuso e dopo il raffreddamento forma sul corpo base uno strato uniforme dallo spessore regolabile tra 10 micron e 100 micron. L'elemento di guarnizione è caratterizzato da grande elasticità e a causa del basso coefficiente di attrito radente del rivestimento (3) risulta particolarmente adatto per le guarnizioni con superfici mobili l'una rispetto all'altra (Fig. 1).
