Abstract
An apparatus and a method are disclosed that form an anodic oxide coating on part of the outer surface of a profile having an irregular cross-sectional shape. A partial anodizing apparatus that is used to partially anodize a profile having an irregular cross-sectional shape includes an electrolytic bath that is divided into two or more partial baths. The profile is held using the two or more partial baths so that part of the profile is situated outside the electrolytic bath to form a sealed electrolysis chamber.
Claims2
A partial anodizing method that partially anodizes a profile having an irregular cross-sectional shape using an electrolytic bath that includes a first partial bath and a second partial bath, the first partial bath having an approximately box-like shape, and being formed of an insulating material, a cathode being disposed on an inner side of the first partial bath, and the second partial bath having an approximately plate-like shape, and being formed of an insulating material, the method comprising:
- disposing first part of the profile that does not form a design surface on the second partial bath through a seal member;
- joining the first partial bath and the second partial bath to hold the profile so that second part of the profile is situated outside the electrolytic bath, an electrolysis chamber having inlets and outlets for an electrolyte solution being formed by joining the first partial bath and the second partial bath;
- and
- discharging the electrolyte solution through the inlets.
