Abstract
Process and system for protecting an oxidizable material against oxidation. The process according to the invention consists of forming a gas-permeable body (1) having open pores (28), a first surface (2) intended to come into contact with an oxidizing gaseous flow (4) liable to oxidize the body and a second surface (6) opposite to the first surface and injecting an oxygen-free protective gas (8) through the second surface (6) leading to disturbances in the material giving it a protection against oxidation.
