SOUND-AND/OR VIBRATION-DAMPING COATING,ELEMENT PROVIDED WITH SAID COATING AND PROCESS FOR APPLYING THE LATTER

摘要

Sound-insulating and/or vibration-damping cover, comprising a layer of a relatively hard substance (2) which has pores, interstices, cavities (3) and/or hollows (12) containing a material (4) which has a greater plasticity or elasticity than said substance (2). This cover can be applied to an element by subjecting the surface of the latter to be covered to a surface treatment in order to ensure adhesion of the layer of the substance (2), by applying this layer (2) on the surface thus treated by projection of this substance in an at least partially molten state and in the form of droplets and by introducing the material (4) into the cavities (3). ……
