Signs and Symptoms of Psoriasis. Psoriasis is a common autoimmune skin disorder which occurs when the skin cells replicate too quickly. The skin produces new cells at many times the normal rate, creating inflamed, scaly and red patches of skin, called plaques, where the old skin has not shed quickly enough.
Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.
Galvanic corrosion is a process that degrades metals electrochemically. This corrosion occurs when two dissimilar metals are located in contact with each other in the presence of an electrolyte, such as salt water, forming a galvanic cell.
