Abstract (en)
[origin: WO9848077A1] The invention relates to a metal layer with open porosity and with a maximum thickness of 500 mu m, whereby the diameter of the through pores is at most a twelfth of the thickness of the layer. In order to produce a metal layer with open porosity, a suspension containing metal powder, dispersant as well as substances for adjusting the viscosity is deposited in layers on a support, dried and then sintered. The thickness of the suspension layer deposited on the support must be such that the thickness of the metal layer after sintering is at least three times the diameter of the metal powder.
