Porosity in castings can be cured.
Non surface connected porosity is routinely removed by treating the casting(s) at the appropriate 'plastic' temperature under extreme high pressure in inert Argon gas. These pressures can be as high as 30,000 psi. As the gas is isostatic the casting will not deform and internal non suface connected porosity will be closed.
Sub surface porosity results in surface dimpling and pre-machined valve components that require superior gasket sealing surfaces will benefit from this treatment.
Castings that have small cooling holes running through the casting will not be affected as the gas pressure will flow through these holes.
Typical parts that are routinely treated are: Ceramics for industry, gas turbine parts, aerospace turbine blades and castings. Medical implants, Stainless steel/Duplex valve castings. Copper based castings. Aluminium alloy castings ( turbo wheels, cyclinder heads Aerospace aluminium alloy castings )
Metal matrix composites can be created, diffusion bonding of dissimilar metals ( aluminium to titanium etc )
