A manufacturing method for a rotating machine (100) comprises: a casing formation step (S0) for forming a casing (1) of the rotating machine (100), the casing having openings (5, 6, 10, 11) to suck and discharge a fluid (F); a surface activation step (S2) for activating the inner surface (1a) of the casing (1) by supplying and discharging a pretreatment liquid (W1) into and from the casing (1) through the openings (5, 6, 10, 11); a preheating step (S4) for preheating the casing (1) by supplying and discharging a preheating liquid (W2) into and from the casing (1) through the openings (5, 6, 10, 11); a plating step (S5) for plating the inner surface (1a) of the casing (1) by circulating a plating liquid (W3) by supplying and discharging the plating liquid into and from the casing (1) through the openings (5, 6, 10, 11); and an assembling step (S7) for providing a rotating body (3, 4) such that the rotating body is covered from the outer peripheral side by the plated casing (1). In the surface activation step (S2), the preheating step (S4), and the plating step (S5), when the liquid surface of each of the liquids used in the respective steps fluctuates vertically in the casing (1), each of the liquids is supplied to the inner surface (1a) of the casing (1) in a range above the liquid surface by a treatment liquid auxiliary supply device (18). |
