    摘要： The invention relates to a preform intended for the manufacture of a metal foam having a porosity of between 62% and 85%, wherein it includes a set of precursors in the form of balls formed of a mixture of 12% to 25% of organic binder, 72% to 87% of sodium chloride and 1 to 3% of kalinite, the precursors have a diameter of around 1 to 10 mm and preferably of 4 mm and said precursors are obtained by granulating the mixture using the fluidized bed process.

    摘要： A method of forming a product such as a biomedical implant of Mg or Al includes computationally designing the product including a controlled porous architecture, producing a positive model of the product, infiltrating the model with a salt-containing paste, drying the paste, removing the material comprising the positive model leaving a negative salt template, infiltrating the salt template with molten Mg or Al or alloy, allowing the Mg or Al or alloy to solidify, and removing the salt template to leave the Mg or Al or alloy product with the controlled porous architecture. In some embodiments the method includes controlling the Mg or Al infiltration pressure to control the extent to which a texture or pattern of the internal surfaces of the model is imprinted on the internal surfaces of the end product.

    摘要： A process for producing a metal article containing at least 10% interconnected porosity, using a preform (11), comprising: mixing an organic binder, a wetting agent and a granular material, to obtain a mouldable paste that combines 10 vol. pct. or more of said granular material, said material dissolving easily in a liquid solvent; shaping the paste into an aerated preform and providing an open pore space to be infiltrated by the metal or alloy; evaporating said wetting agent and baking said preform to a temperature sufficient to degrade the binder and create a network of interconnected open porosity in the preform; filling said open pore space with the liquid metal or alloy. All or part of the baked preform can be easily leached by a liquid solvent through the network of fine pores.
