  • METHOD OF MAKING A CLOSED POROSITY SURFACE COATING ON A LOW DENSITY PREFORM
    Publication number: 20010001640
    Abstract: A method of making a low density part with a closed porosity surface coating is formed by applying, to a porous powder preform, a coating of powder finer than that of the preform which is sinterable to a near full density below the melting temperature of the powder; and heating the coated preform to sinter the coating to form a near full density, gas impermeable, closed porosity surface coating on the preform.
