采用电化学测试和表面分析方法, 研究了采用L-PBF技术制备的3种3D打印的NiTi形状记忆合金在37 ℃人工唾液中的腐蚀行为和钝化膜特性。L-PBF NiTi的钝化性受工艺参数及表面形貌和理化性质的影响。结果表明, L-PBF NiTi表面的缺陷在腐蚀初期可以提高钝化膜的形成速率, 但缓慢形成的钝化膜具有最佳的耐蚀性。钝化膜的厚度与其耐蚀性呈正相关。钝化膜的外层主要为Ti的氧化物、内层主要为Ni的氧化物。当线性能量密度为0.2 J·m^−1, 体积能量密度为56 J·mm^−3时制备的L-PBF ...

A 24-year-old male patient was referred to our department for expansion of the constricted maxillary arch as a presurgical procedure for the correction of congenital facial disfigurement. On examination, the patient had a convex profile, increased interlabial gap, tongue thrust, limited mouth opening, posterior crossbite, asymmetric ‘V’-shaped ...

A review of the latest developments in rotary NiTi technology and root canal preparation.
The introduction of nickel-titanium (NiTi) mechanical instruments dramatically changed clinical endodontics over the last few decades. Before NiTi, it was necessary to use more instruments to create an ideal root canal shape, and many approaches ...

Additive Manufacturing: An Opportunity for the Fabrication of Near-Net-Shape NiTi Implants
Nickel–titanium (NiTi) is a shape-memory alloy, a type of material whose name is derived from its ability to recover its original shape upon heating to a certain temperature.
