Abstract
A high-damping composite material, which consists of a metal or metal alloy base material having poor damping properties which determines the strength and shape of said material, and a metal or metal-alloy surface layer surrounding said base material on all sides which has high mechanical damping properties.
Claims8
A procedure for manufacture of machine components which are highly stressed mechanically and thermally, comprising:
- forming said machine components from a metal or metal alloy base material having poor damping properties which determines the strength and shape of said component;
- and
- subsequently coating all the surfaces of the resulting component with a metal or metal alloy having high damping characteristics sufficient to improve the lifetime of said machine component.
In a machine component subjected to mechanical and thermal stresses, the improvement which comprises:
- said component comprising a structure consisting of a metal or metal alloy base material having poor damping properties which determines the strength and shape of said component and a metal or metal alloy surface layer surrounding said base metal on all sides having high mechanical damping properties sufficient to improve the lifetime of said machine component.
