METHOD FOR MAKING A CHEMICAL DEVICE ELEMENT COMPRISING A METAL SUPPORTING PART AND AN ANTI-CORROSIVE METAL COATING
The invention concerns a method for making assembly parts (101, 192, 111, 112) for manufacturing a chemical device element (100) comprising fixing an anticorrosive coating (31, 32) on an untreated assembly part (21, 22), by an operation including a brazing process under controlled atmosphere and, optionally forming the coated part (101, 102) by plastic deformation. The brazing temperature is preferably lower than about 750 DEG C, and more preferably ranging between 600 DEG C and 720 DEG C. The inventive method enables an anticorrosive coating having a thickness less than 1 mm to be firmly fixed on a steel plate.
