Abstract
Process for the manufacture of a containment element for a fluid heated to a temperature exceeding 850.degree. C. A blank made of a refractory metal alloy is coated with a glass-based adhesive, at least one film made of a glass suitable for the material and the plasticity temperature of the blank is laid down on it, the blank is heated to the plastic temperature and subjected to a first stamping operation to shape the chamber of the containment element, followed by a second stamping operation to form the inner or outer flaps of the chamber. The element is then cooled, and finally, heat-treated.
Claims16
A process for manufacturing a containment element designed to hold and allow the flow of a fluid heated to a temperature greater than 850.degree. C., comprising the steps of:
- a) providing a blank made of a heat-resistant metal alloy;
- b) coating the blank with an adhesive containing a mineral material,
- c) depositing on the blank at least one film made of a mineral material suitable for the material and the plastic temperature of the blank,
- d) heating the blank to the plastic temperature of the heat resistant metal alloy, which plastic temperature is above 850.degree. C.,
- e) performing a first stamping operation on the heated blank to form a chamber of the element,
- f) performing a second stamping on an end of the chamber to produce flaps,
- g) cooling the element, and
- h) heat treating the element, the element being suitable for holding and allowing the flow of a fluid heated to a temperature greater than 850.degree. C.
