“…The proposed coatings showed increased hardness and enhanced mechanical properties [128]. The addition of rare earth oxides refined the microstructure, reduced the loss of weight, and increased the bonding strength between coating and substrate, and improved the degradability of the sample [9], [69]. In cladding process using bioactive ceramic, CaO is formed which is considered toxic for osseoblast.…”

“…Laser surface cladding is a rapid solidification technique that could overcome the aforementioned difficulties with many advanced features, such as thick coatings, low dilution ratio, high cooling rate, crack-free layer, reduction or elimination of porosity, limited heat affected zone with low thermal distortion, high refined microstructure, and strong metallurgical bond between coating and substrate [30]. In order to overcome the restriction of titanium alloys in machinery performance and safety at low cost with high value elements, laser cladding is employed to fabricate coatings with advanced tribological properties and high-temperature oxidation resistance [31].…”

Over the years, engineering materials are being developed due to the need for better service performance. Wear, a common phenomenon in applications requiring surface interaction, leads to catastrophic failure of materials in the industry. Hence, preventing this form of degradation requires the selection of an appropriate surface modification technique. Laser surface modification techniques have been established by researchers to improve mechanical and tribological properties of materials. In this chapter, adequate knowledge about laser surface cladding and its processing parameters coupled with the oxidation, wear and corrosion performances of laser-modified titanium has been reviewed.

Порошковая металлургия и функциональные покрытия 4 2015 Введение В изделиях современного авиа-и машиностро-ения широкое применение находят титановые α + β-сплавы благодаря высоким прочностным и антикоррозионным свойствам, а также хорошей свариваемости. Они используются в крупнога-баритных сварных конструкциях летательных аппаратов [1]. Однако из-за высокой склонности к схватыванию и задиранию при работе на тре-ние скольжения их применение для изготовления УДК 621.9.048.7 DOI dx.doi. org/10.17073/1997-308X-2015-4-40-44 Упрочнение и наплавка волоконным лазером как способы целенаправленного формирования структуры и свойств титанового сплава ВТ6 © 2015 г. А.И. Горунов, А.Х. Гильмутдинов Казанский национальный исследовательский технический университет (КНИТУ) им. А.Н. Туполева Статья поступила в редакцию 13.11.14 г., доработана 24.04.15 г., подписана в печать 28.04.15 г.Приведены результаты изучения микроструктуры и твердости поверхностных слоев наплавленного с использованием воло-конного лазера никелевого сплава на титановый α + β-сплав после их комбинированного упрочнения при воздействии ла-зерного излучения. Лазерная наплавка позволяет получать покрытия с высокой твердостью и закалочными структурами в поверхностных слоях титанового сплава. Твердость наплавленного металла после высокоскоростного охлаждения с темпе-ратуры расплава на поверхности титановой подложки в 2,7 раза больше твердости мартенситного слоя, сформированного в титановом сплаве после закалки.Ключевые слова: лазерная наплавка, лазерное упрочнение, титановый сплав, микроструктура, микротвердость. The results of studying microstructure and hardness of surface layers of nickel alloy welded on titanium α + β alloy using fiber laser after their combined hardening under the effect of laser radiation are presented. Laser cladding makes it possible to form coatings with high hardness and quenching structures in surface layers of titanium alloy. Hardness of welded metal after the high-speed cooling from the melt temperature on the titanium substrate surface is larger than the density of martensite alloy formed in the titanium alloy after quenching.Keywords: laser cladding, laser hardening, titanium alloy, microstructure, microhardness.
