Abstract
The present invention relates to a sintered porous metal plate which comprises metal particles directly and integrally bonded together by sintering under pressure, said plate being of a porous structure and having a density gradient in the direction of thickness. The present invention is also directed to a method of making such a sintered porous plate.
Claims4
A sound absorbing or vibration absorbing sintered porous metal plate which comprises metal particles directly and integrally bonded together due to sintering and pressing without the use of a binder material, said plate being of porous structure and having a continuous density gradient in the direction of thickness and a multi-layer structure comprising two coarse layers with a dense layer therebetween.
