Gasket e.g. for cylinder head has electrically insulating coating on outer sealing layer

摘要

The gasket (100) has an outer sealing layer with an electrically insulating coating on the side facing the component with the first (baser than aluminum) metal content. This coating is so resistant to abrasion and expulsion that the material of the first component and that of the second component never come into contact with each other during the life of the gasket.
