Niobium hauv kev kho hniav kho hniav

The application of metal dental restorations in oral prosthetics has become very widespread and popular. Due to the complexity of the intraoral environment, it has been the focus of research to improve the mechanical and chemical properties, especially the corrosion resistance, to increase the durability of restorations under the premise of ensuring the good biocompatibility of the materials.Haoka et al. tested the electrochemical properties of niobium-containing magnetic attachments, and the results showed that compared with the traditional magnetic attachments, the magnetic attachments made of Pt-30.0mass%Fe-0.6mass%Nb alloys had better corrosion resistance.Lee et al. tested the electrochemical properties of titanium-niobium alloys. Lee et al. tested the structural properties of titanium-niobium alloys and showed that Ti-10Nb and Ti-27.5Nb alloys had the highest strength, while Ot' phase-dominated (17.5Nb, 20Nb) alloys and B-phase-dominated alloys (>30Nb) muaj qhov qis tshaj modulus ntawm elasticity. . Tsis tas li ntawd, tag nrho cov titanium-niobium alloys koom nrog hauv cov kev ntsuam xyuas pom tau zoo heev corrosion kuj.

Kikuchi et al. kuaj cov khoom siv ntawm cam khwb cia titanium-niobium alloys uas muaj qhov sib txawv ntawm lub ntiajteb txawj nqus ntawm niobium, thiab cov txiaj ntsig tau pom tias qhov hardness ntawm titanium alloys muaj 5 wt% niobium tau txhim kho zoo; titanium alloys uas muaj 10 wt% niobium thiab saum toj no qhia tau tias muaj txiaj ntsig zoo thiab muaj zog tensile, thaum elongation txo qis; titanium alloys muaj 30 wt% niobium pom zoo abrasive zog thaum tuav lub hardness ntau dua, lub zog, thiab modulus ntawm elasticity. Kev kawm los ntawm Hu Xin et al. kuj tau lees paub tias lub siab-lub zog, siab modulus ntawm elasticity titanium-zirconium-niobium-tin alloy yog cov khoom siv hlau uas muaj biosafety zoo rau kev kho qhov ncauj, tab sis cov txheej txheem hnav hloov pauv los ntawm kev hnav mus rau cov nplaum hnav nrog qhov nce ntawm qhov chaw load.
