Sintered acoustic and oscillation dampening material

摘要

The sintered acoustic and vibration dampening substance comprises metal or metal alloy, which enables a carbide formation by chemical reaction, and carbon in the form of graphite, where the amount of the graphite is 50 vol.%. The portion of carbide contained in the substance is less than 35 vol.%. The substance has an E-module of 50 GPa and the product of the E-module has a value of 0.4 GPa with a geometrical-independent damping factor in an axial direction. The theoretical thickness of the substance is 80%. An independent claim is included for a method for preparing a substance.
