氮化钛涂层磁体

FDA要求用于体内的永磁体必须具有批准的生物相容性涂层，包括 聚对二甲苯涂层的磁铁 和氮化钛涂层磁铁。

氮化钛 is a fourth transition metal nitrides which combined the characteristic of metallic crystal and covalent crystal due to the hybrid structure constituted of metallic bond and the covalent bond.是一种第四过渡金属氮化物，由于金属键和共价键的混合结构而结合了金属晶体和共价晶体的特性。 Titanium Nitride coating has several merits, such as superior thermal properties, chemical inertness, conductivity, metallic reflectivity, high melting point and hardness.氮化钛涂层具有多种优点，例如优异的热性能，化学惰性，导电性，金属反射率，高熔点和硬度。 Titanium Nitride coating is then widely applied to different kinds of cutting tools and mechanical parts as a hard wear-resistant film.然后，氮化钛涂层作为硬质耐磨膜广泛应用于各种切削工具和机械零件。 It also served to decoration industry as decorative film in the meanwhile.同时，它也作为装饰膜用于装饰行业。 Besides, Titanium Nitride thin film can serve as the conductive film and protective film of electrochromic device, or reflective film and antistatic film of display device.此外，氮化钛薄膜可以用作电致变色器件的导电膜和保护膜，或者用作显示器件的反射膜和抗静电膜。 Titanium Nitride has very strange optical properties that has high reflectance in red waveband of the visible region, while exhibit low reflectance near ultraviolet region and thus obtained smoothly golden yellow appearance.氮化钛具有非常奇怪的光学性质，其在可见光区域的红色波段中具有高反射率，而在紫外光区域附近具有低反射率，因此获得了平滑的金黄色外观。

• 厚度在2〜3μm左右，符合环保要求。
• 磁铁和涂层之间有很强的附着力。
• 工作温度可以达到500摄氏度。
• 杨氏模量可以达到350〜600 GPa。

实际上，有时客户很难区分氮化钛涂层磁体和 涂有永磁铁的磁铁 only from their appearance.仅从它们的外观来看。 The extraordinary corrosion resistance and non-reactivity features will guarantee Titanium Nitride coated magnets slow down the release of the metal ion and reduce toxicity of metal material to the surrounding media.出色的抗腐蚀性和非反应性特性将确保氮化钛涂层磁体减慢金属离子的释放速度，并降低金属材料对周围介质的毒性。
