Abstract:
In recent years, black nickel-based functional coatings are increasingly being used as a worthy alternative to chromium coatings on steel, since such coatings provide not only an aesthetic appearance, but also effective corrosion protection.The known technologies of applying black nickel coatings do not allow obtaining coatings with the required corrosion and wearing resistance. In addition, these technologies involve the mandatory pre-deposition of copper or nickel underlayer. [..]

Abstract:
One of the methods of protection of metal surfaces from an aggressive environment is the formation of continuous coating on their surfaces with water-repelling properties and a self-cleaning ability, which give the material superhydrophobic properties and also protect them from contamination.A solution for hydrophobization of aluminum alloy 5556 in a solution containing dimethyl sulfoxide and water in a ration of 7:1 and also stearic acid in the amount of 0.01 mol/L was developed.It was determined that the newly-formed coating in this solution is characterized by a contact angle of θс = 151°. The protective ability of coatings determined by the drop method as the time until the appearance of corrosion product under the drop of Akimov solution amounts to 125 s.Corrosion tests of AA 5556 speciments with hydrophobized surface were conducted (ASTM B117) in a salt fog chamber in the developed solution.

Abstract:
In surgery, besides the joint replacements that need permanent prosthesis implantation in the human body, there are many other clinical cases, such as bone fracture, cardiovascular diseases, in which the temporary implant materials are needed. The fixation or mechanical support are there temporarily needed during the healing process of the injured or pathological tissue, and after that, the implants accomplish their mission have no longer function in human body.
