Estimating the term…
The present invention is directed to porous metal products including ceramic particles, where the initial surface layer (12) of the particles (10) is modified with agents that interact with surface oxygen, oxides and/or hydroxides to improve the wettability of particles within a molten metal alloy, and where the ceramic particles (10) are modified (14) by contacting the particles with a surface-modifying agent and heating the ceramic particles and surface-modifying agent to an elevated temperature at which the ceramic particle remains substantially stable and the surface-modifying agent becomes at least partially thermally unstable, to cause a reacted layer (16).
A method of making a porous metal product comprising:
A method of making a ceramic particles having a dispersion-enhancing surface layer, the method comprising:
Ceramic particles for use in the manufacture of porous metal products comprising:
A porous metal product comprising:
