Abstract
A method of manufacturing a protective insert (1) on a metal part (2) in which a foil (3) that serves as a barrier for gases is fixed between the part (2) and the insert (1), the edges of a metal capsule (4) are fixed to the edges of the foil (3), the space (5) between the capsule (4) and the part (2) is filled with a metal or ceramic powder and the ends of the capsule (4) are closed, the part (2) together with the filled capsule (4) are inserted in an isostatic pressing oven under a controlled atmosphere, with the pressure and the temperature being selected so that the powder is pressed in situ. The part (2) is cooled and then the capsule is removed before giving the part (2) together with its insert (1) the desired final shape. The method is very simple and it enables reliable products to be obtained.
