Thermal stability of nitride coatings formed by ion–plasma deposition

Steel surface TiCrN, TiMoNcoatings structural phase state change features after low-energy alpha particles irradiation

“…The vacuum deposition modes have been the following: Ti and Cr cathodes, nitrogen residual pressure (P N = 10 −1 Pa), stress shear 60 V, cathode current 100 A, deposition time 60-120 s. As result the samples series 50÷150 mm wide with the TiCrN coatings with the approximately equal titanium and chromium content have been obtained. The coatings deposition procedure is set out in great detail in [6,8] papers.…”

“…Often the transition metals nitrides are used as coatings [4,5]. These compounds combine ceramics and metal properties and have increased hardness, wear resistant and corrosion stability, thermal stability [6][7][8]. The transition metals TiCrN, TiZrN, TiMoN and other nitrides coatings are considered to be perspective as protective coatings [9,10].…”

Effects of Irradiation with Low-Energy and High-Energy Krypton Ions on the Structure of TiCrN Coatings

“…The series of TiCrN coatings with an approximately equal content of titanium and chromium on carbon steel, with a thickness of 50-100 nm, were formed. The procedure of coating formation is presented in detail in papers [5,7]. The specimens were disks with a diameter of 15 mm and thickness of ≈1 mm.…”

“…Interest in nitrides of transition metals is due to their special physical and mechanical properties, combining both properties of ceramics and metals. Coatings based on nitrides of the transition metals possess the enhanced hardness, wearand corrosion resistance, thermal stability [5][6][7] that allow considering them as perspective protection for struc- * corresponding author; e-mail: skislitsin@mail.ru tural materials. Nitride coatings have already been examined as a perspective for covering of surface cladding of gas-cooled fast reactors (GFR) [8] and it makes current studies of their radiation resistance.…”

The Structure of Composite Coatings Based on Titanium Nitride, Formed Using Ion Bombardment Condensation

“…Ключевые слова: покрытия, КИБ, нитрид титана, сталь 110Г13Л, ВК8, химический состав, электронная структура DOI: 10.25206/2310-9793-7-1-201-207 I. ВВЕДЕНИЕ Нанесение износостойких покрытий на основе нитрида титана на рабочие поверхности различных изделий, в том числе элементов газотурбинных двигателей и двигателей внутреннего сгорания, работающих в условиях повышенной температуры и скорости, является одним из наиболее встречаемых способов повышения их технологических характеристик [1,2]. Одним из методов нанесения TiN покрытий является конденсация вещества из плазмы в вакууме с ионной бомбардировкой поверхности (КИБ) [3]. Преимущество метода КИБ по сравнению с методом магнетронного распыления заключается в формировании высокой адгезии покрытия к подложке благодаря достаточно высокой энергии ионов во время процесса предварительной очистки и скорости образования покрытий.…”
