Abstract: Disclosed articles as results of a microarc oxidation process, or plurality thereof, which are not limited by size, specifically by certain dimensions of their size, such as their length. Different sections or surfaces of articles of the invention may be subjected to a microarc oxidation process at any given time, such as by gradually subjecting a surface of an article to a microarc oxidation process, or such as by sequentially subjecting different sections of an articles to a microarc oxidation process. Further-more, disclosed are methods for manufacturing of articles of the invention, or otherwise for subjecting articles of the invention to a microarc oxidation process, or plurality thereof. In some examples, tubes of above 6 meter in length may be coated according to methods of the invention. The coating of said tubes may be beneficial for desalination applications. In other examples, only grooves of pulleys are coated.
