goldhaltiges compound for the manufacture of highly porous coatings

摘要

For making highly porous coatings on metal surfaces by sintering, known gold compositions are used, and 1 to 10% by weight of a pore former are added thereto, which consists of a material which abruptly decomposes or vaporises at 700 to 1050 DEG C and escapes from the layer without leaving a residue. Preferably, plastics and dental waxes in powder form are used for this purpose.
