Abstract

PURPOSE: To manufacture a homogeneous boiling heat transfer tube in a short time by electrolytically dissolving the surface of an austenitic stainless steel tube as a positive electrode while stirring an electrolyte soln. to make the surface porous.
CONSTITUTION: The top and bottom of sensitized austenitic stainless steel tube 1 are clogged with rubber plug 2, 2'. Tube 1 is concentrically fixed to copper cylinder 4 as a cathode with rubber support rings 3, 3', mounted on rubber seats 5, 5', and dipped in glass container 7 filled with electrolyte soln. 6 such as hydrochloric acid or mixed aq. soln. of NaCl and HCl. Rings 3, 3' and seat 5' are provided with holes or notches through which soln. 6 is circulated. Tube 1 and cylinder 4 are connected to positive and negative electrodes, respectively with controlled potential electrolytic unit 8, and a current is supplied while turning stirring blade 9 with motor 10 to circulate soln. 6 in the direction of arrow 11, whereby the surface of tube 1 is dissolved and made porous.
