“…Studies are based on the fact that their inherent material characteristics, such as crystallinity, surface topography, wettability, and surface chemistry can affect stem cell behaviour and in-vivo osseointegration [2,3]. Various surface modification methods, such as sol-gel formation, chemical treatment, electrochemical treatment, plasma spray deposition, thermal oxidation, etc., are employed to enhance wear resistance, corrosion resistance and bio-mineralization for achieving improved osseointegration [4][5][6][7][8][9][10][11][12][13][14]. From the wide variety of techniques available, thermal oxidation could be considered as one of the most straightforward processes where the oxide layers are grown epitaxially on the substrate by annealing the alloy at higher temperatures in the presence of oxygen.…”

“…The major requirements for a typical biomaterial are biodegradability, enough strength and excellent efficiency to interact with the surrounding tissues and bones in the body. These criteria can be achieved by developing bioactive porous ceramic-ceramic scaffolds which can trigger the regeneration of new bone tissues and the biomechanical load tolerance during bone formation [1][2][3][4]. Forsterite (Mg 2 SiO 4 ) is a bioceramic having mechanical properties superior to hydroxyapatite (HAp) and bioglass [5].…”

“…Наиболее широкое применение для нанесения керамических покрытий, в том числе из материалов на основе оксида алюминия-оксида титана, получил метод плазменного напыления. Покрытия на основе оксида алюминия-оксида титана с добавками твердых смазок отличаются от покрытий из чистых оксидов лучшей пластичностью и повышенной стойкостью по отношению к ударным нагрузкам, а также обладают меньшими значениями пористости, равномерностью структуры и изотропностью свойств [12][13][14][15]. Снижение пористости покрытий системы объясняется тем, что при введении в высокотемпературную газовую струю композиционного материала в первую очередь плавится твердая смазка и обволакивает зерна оксида.…”
