To provide a method for producing a cylinder block made from an aluminum alloy, which satisfies low frictional properties while satisfying adequate adhesiveness to a substrate and low aggressiveness to a sliding counterpart, and to provide the cylinder block made from the aluminum alloy.
The method for producing the cylinder block made from the aluminum alloy which has the plated film formed on a surface of the cylinder bore by using a plating solution containing SiC having an average particle diameter of 4.5-5.5 μm includes: a first stage of a film-forming step of conducting an electroplating operation under such a condition that the flow rate of the plating solution in the vicinity of the surface of the cylinder bore is 120 cm/s or more and current density is 10 A/dm2 or less; and a second stage of the film-forming step of conducting the electroplating operation under such a condition that the flow rate of the plating solution is 80-120 cm/s and the current density is 10 A/dm2 or more, after the first stage of the film forming step.
