Corrosion of Nitrided Titanium in Hydrofluoric Acid

Surface Characterization of Titanium Implants Treated in Hydrofluoric Acid

The results of XPS measurements of commercially pure titanium (cp-Ti) before and after chemical treatment are presented. We have measured XPS spectra of core levels (Ti 2p, O 1s, C 1s, F 1s) and valence bands of coarse-grained cp-Ti before and after standard acid treatment accepted in dentistry (in 1% HF and 40% HF for 1 min). It is found, that acid treatment of cp-Ti reduces the content of hyd...

Corrosion Behavior of Titanium in Artificial Saliva by Lactic Acid

As one of the main products produced by oral microorganisms, the role of lactic acid in the corrosion of titanium is very important. In this study, the corrosion behavior of titanium in artificial saliva with and without lactic acid were investigated by open-circuit potentials (OCPs), polarization curves and electrochemical impedance spectroscopy (EIS). OCP firstly increased with the amount of ...

Etching with Hydrofluoric Acid

Photoresists, wafers, plating solutions, etchants and solvents ... Phone: +49 731 977343 0 www.microchemicals.eu [email protected] Etching of SiO2, Quartz, and Glasses with HF Hydrofluoric acid is the only etchant which attacks amorphous SiO2, quartz, or glasses at significant high etch rate. However, HF is not only a strong corrosive, but also highly toxic towards higher concentrations: ...

Improving Corrosion Resistance and Biocompatibility of Magnesium Alloy by Sodium Hydroxide and Hydrofluoric Acid Treatments

Owing to excellent mechanical property and biodegradation, magnesium-based alloys have been widely investigated for temporary implants such as cardiovascular stent and bone graft; however, the fast biodegradation in physiological environment and the limited surface biocompatibility hinder their clinical applications. In the present study, magnesium alloy was treated by sodium hydroxide (NaOH) a...
