Abstract
A metallic object formed of metal particles compressed together to form a rigid object. Each of the metal particles is coated with a metal having a melting temperature lower than that of the metal of the particles. The coating metal fills the voids between the particles so that the object is impervious to fluids.
Claims14
A method of making an impervious metal body comprising the steps of
- completely coating iron powder particles with a layer of copper which is about 12% to about 30% by weight of the body,
- compressing said coated particles together, and heating the compressed particles to a temperature at which the copper layer melts and the melted copper flows and fills the voids between the particles.
An impervious metal body produced by completely coating iron powder particles with a layer of copper which is about 12% to about 30% by weight of the body, compressing the coated particles together, and heating the compressed particles to a temperature at which the copper layer melts and the melted copper flows and fills the voids between the particles.
