翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Nitinol biocompatibility ： ウィキペディア英語版 Nitinol biocompatibility Metal implants containing a combination of biocompatible metals or used in conjunction with other biomaterials are often considered the standard for many implant types. When materials are introduced to the body it is important not only that the material does not damage the body, but also that the environment of the body does not damage the implant.〔''Biocompatibility of Implants'' http://www.corrosion-doctors.org/Implants/biocompatib.htm〕 One method that prevents the negative effects resulting from this interaction is called passivation. Passivation is a process that removes corrosive implant elements from the implant-body interface and creates an oxide layer on the surface of the implant. The process is very important for making biomaterials more biocompatible. The following investigation will examine passivation as it relates to NiTi, nitinol, a commonly used biomaterial especially in the development of stent technology. Nitinol, which is formed by alloying nickel and titanium (~ 50% Ni), is a shape memory alloy with superelastic properties much similar to that of bone in comparison to that of stainless steel (another commonly used biomaterial). This property makes nitinol an especially advantageous material for biomedical applications. Some of the biomedical applications that utilize nitinol, include stents, heart valve tools, bone anchors, staples, septal defect devices and implants. ==Overview of common passivation methods== In general, passivation is considered to be a process that creates a non-reactive layer at the surface of materials, such that the material may be protected from damage caused by the environment. Passivation can be accomplished through many mechanisms. Passive layers can be made through the assembly of monolayers through polymer grafting. Often, for corrosion protection, passive layers are created through the formation of oxide or nitride layers at the surface. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nitinol biocompatibility」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
