Problems solved by technology

Therefore, when the anodic electrolytic etching treatment is performed on the inner peripheral surface of the cylinder as a pre-plating process, the etching depth decreases at low temperature positions, and therefore, a decrease in plating adhesion and uniformity may occur in plating

[0079] [The second embodiment ( Figure 6 )]

[0080] Figure 6 A second embodiment of a surface treatment device according to the invention is shown. In the second embodiment, the same parts as those of the first embodiment are denoted by the same reference numerals and descriptions thereof are simplified or omitted here.

[0081] The electroplating apparatus 50 according to the second embodiment is different from the surface treatment apparatus 10 according to the first embodiment in that the hot air blowing ports of the hot air blower 30 are provided at a plurality of positions, for example, around the On the two positions of the cylinder block 100 of the electroplating device 50 facing each other, the hot air is simultaneously blown onto the cylinder block 100 from the hot air blowing port.

[0082] According to this second embodiment, the advantages (1) and (2) of the first embodiment and the following advantage (3) can be obtained.

[0083] (3) The hot air blowing po...

Abstract

In a method of pre-plating surface of the object to be processed by using a surface processing device provided with electrodes, the electrode is located to face to the surface to be processed; the treatment fluid is led between the electrode and the surface of the object to be processed so that the electrode and the surface of the object to be processed are conducted; in the process of pre-plating, the hot air is blown to the object to be processed to the external part, and the surface of the object to be processed is heated to the reaction temperature for pre-plating.

Description

technical field [0001] The invention relates to a method for pre-plating the surface of an object to be treated, for example, pre-plating the inner peripheral surface of an engine cylinder block before electroplating, and also relates to a surface for performing the pre-plating method Processing device. Background technique [0002] Conventionally, Japanese Patent Application Laid-Open No. 9-3687 (Patent Publication 1) discloses a method of heating a cylinder block in the process of pre-plating the cylinder inner peripheral surface of the cylinder block. In this heating method, the treatment liquid stored in the cylinder bore of the cylinder block is heated by a heater provided in the cylinder bore. [0003] However, in the anodic electrolytic etching process as pre-plating processing of the inner peripheral surface of the cylinder bore of the cylinder block combined with the cylinder head, electrodes are provided in the cylinder bore, so it is difficult to install a heater...
