Microstructural and Tribological Characterization of Duplex Coatings with Additional Ion Bombardment D.Kaka1,M.Rakita2,B.3 (1.s)(Faculty for Technical Sciences, University of Novi Sad, Serbia... coating treatment of steels. In the paper are presented characteristics of hard coatings, type TiN, produced by classic technology PVD (physical vapour deposition) and IBAD (ion beam assisted deposition......
characterizations of the films were carried out using X-ray diffractometry (XRD) and high-resolution transmission electron microscopy (HR-TEM). The results indicated that increasing ion bombardment... of the films were also affected. Based on the experimental results, the evolution mechanisms of the film microstructure and properties were discussed by considering ion bombardment effects. Key words......

; 而到1200V时, 晶粒度较未辅助略大, 但却具有很高的硬度以及较高的断裂韧性, 说明硬度和断裂韧性的提高还与离子束轰击导致薄膜的致密化增加有关. 关键词: 离子轰击; 晶粒度; 硬度; 断裂韧性 中图分类号: TG174.44 文献标识码: A Effect of ion bombardment on fracture toughness of Cr-N coatings... magnetron sputtering (IBAMS). The microstructure was characterized by FESEM, AFM and XRD analysis. The effects of ion bombardment energy on microstructure, grain size, hardness and fracture toughness......
University,Beijing 100084,China摘 要:<正>To simulate irradiation damage,argon ion was implanted in the Zircaloy-4 with the fluence ranging from 1×1016 to 1×1017 cm-2,using accelerating implanter at an extraction voltage of 190 kV and liquid nitrogen temperature.Then the infuence of ar- gon ion implantation on the aqueous corrosion behavior of Zircaloy-4......
; Abstract: A new nitriding process was used to carry out the ionic bombardment, in which nickel ion was introduced. The microstructure, composition and properties of the treated stainless steel were studied... stainless steel. However, as compared with the traditional ion-nitriding stainless steel, the corrosion resistance is greatly improved. Key words: stainless steel; nitriding; ionic bombardment......
to the higher bombardment effect of Cr target, the surface of the coating with higher Cr content is obviously ion-etched.
