19、essed by using an electrolytic bath at low temperatures or a par- ticular electrolytic bath to which various kinds of organic acid are added. They are characteristically harder and excellent in abrasion resistance in compari- son with coatings processed by an ordinary method. They are generally not
20、processed by sealing of anodic oxide coating. When corrosion resistance is required, sealing of anodic oxide coating is car- ried out. However, the abrasion resistance is apt to be decreased in that case. b) abrasion resistant standard specimen A specimen prepared by following the specification give
21、n in Annex 1 (normative), in order to correlate the results of abrasion resistance tests carried out at respective test places. 4 Classification Coatings shall be classified() as given in Table 1 according to the materials of basis metal.
