| description | A method of production of an inexpensive corrosion-resistant heat exchanger made of stainless steel including the steps of electroplating chrome to a thickness of 15 mu m on at least one of the end faces of a plurality of first and second shaped plates made of stainless steel alternately stacked in the thickness direction so as to form a chrome-based brazing filler metal layer, then electrolessly plating or electroplating Ni-P to a thickness of 35 mu m on the chrome-based brazing filler metal layer to form a nickel-based brazing filler metal layer. The first and second shaped plates are brazed together through the chrome-based brazing filler metal layer and the nickel-based brazing filler metal layer to obtain a high corrosion resistant heat exchanger. Further, a fine metal structure can be realized in the high corrosion resistance brazing filler metal filler and therefore the occurrence of cracking at the grain boundaries of the metal structure can be reduced. |
