“…Intermediate titanium coating was formed by vacuum-arc method on the Complex Plant (CP) in TPU [3]. During the formation of the primer valve group metal on the surface of stainless steel the CP was equipped with four vacuum arc plasma generators with titanium cathodes, the gas plasma generator and short-pulse high-frequency bias voltage generator.…”

The hybrid method allows the formation of biocomposites on stainless steel implants. Such multilayer coatings consist of a titanium primer layer and a microarc calcium-phosphate coating. The composite structure of the coating allows combining the properties of good strength stainless steel with high bioactivity of calcium-phosphate layer. It is expedient to use such biocomposites for implants which carry heavy loads and are intended for long-term use, e.g. total knee endoprosthesis.

This study reports a hybrid method which allows the formation of biocomposites on stainless steel implants. The main idea of the method is to create multilayer coatings consisting of titanium primer layer and a microarc calcium-phosphate coating. The titanium layer is deposited from plasma of continuous vacuum-arc discharge, and calcium-phosphate coating is formed by the microarc oxidation technique. The purpose of the hybrid method is to combine the properties of good strength stainless steel with high bioactivity of calcium-phosphate coating. This paper describes the chemical composition, morphology characteristics, adhesion and the ability of the formed biocomposites to stimulate the processes of osteoinduction. It is expedient to use such biocomposites for implants which carry heavy loads and are intended for long-term use, e.g. total knee endoprosthesis

“…The Ti underlayer and TiN coatings were deposited in a hybrid «Arc spectrum» technique which was developed in Tomsk Polytechnic University. Vacuum arc evaporator with coaxial plasma filter (designed by authors [9,10]) was used for AIP method. Firstly, the chamber was evacuated to a base pressure of lower, than 2.5×10 -3 Pa. Before deposition, samples were subjected to ion bombardment in an argon glow discharge at 1500 V for 5 min.…”

IntroductionThe problem of protection of structural and functional materials operating in hydrogen-containing ambient in nuclear reactors and fuel cells is very important. In Russian Water-Water Energetic Reactor (WWER) and High Power Channel Reactor (RBMK) the Zr1%Nb alloy is used as a cladding material. Zirconium and its alloys are susceptible to hydrogen corrosion and fretting wear. It is known that the certain concentrations of hydrogen in the bulk of the material leads to embrittlement and subsequent degradation of mechanical properties [1][2][3][4][5][6]. Titanium nitride (TiN) deposited by vacuum ion-plasma methods is promising in protection zirconium alloys from hydrogen corrosion [7]. Moreover, TiN coatings have an excellent erosion resistance, which favorably affects the fretting resistance of the coatings [8]. There is no scientific data in information about hydrogen sorption kinetics by TiN coated zirconium alloy by dcMS method. At the same time, such studies are of great practical importance for the development of TiN coating technology, allowing to work in extremal conditions. One of the most important tasks in the development of coating technology is to ensure good adhesion of the coating under thermal cycling. The differences between temperature expansion coefficient of the coating and substrate materials leads to the coating degradation and varios accidents can occur. In this paper the problem of stability of the coatings under thermal cycling was solved by creating a Ti underlayer deposited by AIP between the zirconium alloy Zr1%Nb and magnetron sputtered TiN.The aim of this work is to create a stable hydrogen-impermeable TiN-based protective coating under thermocycling conditions using the AIP and dcMS methods.
