In vitro effect of anodization of titanium abutments on their tensile bond strength to implant-supported lithium disilicate all-ceramic crowns

Dental Research Journal, 2023
Background: The retention of cement-retained implant-supported restorations can be affected by surface treatments such as anodizing. This study aimed to assess the effect of the anodization of titanium abutments on their tensile bond strength to implant ...

Performance impact of honing dynamics on surface finish of precoated cylinder bores [PDF]

, 2013
The surface modification of engine cylinder bores with improved sliding properties is often produced by the honing process. This multi-stage process is performed using abrasive stones loaded against the bore with simultaneous rotation and oscillation. To

Effect of particle size on the surface properties and morphology of ground flax [PDF]

, 2013
Flax fibers were ground with a ball-mill and four fractions with different size ranges were collected by sieving. These were tested for water sorption, degree of polymerization (DP), copper number, hydroxyl number and analyzed by X-ray diffraction (XRD),

RF and Surface Properties of Superconducting Samples [PDF]

, 2011
The surface resistance Rs of superconducting cavities can be obtained from the unloaded quality factor Q0. Since Rs varies strongly over the cavity surface its value must be interpreted as averaged over the whole cavity surface.

Nitriding of titanium by hollow cathode assisted active screen plasma and its electro-tribological properties

, 2021
Publisher Copyright: © 2021 Elsevier B.V.Titanium presents good corrosion resistance, a high strength-to-weight ratio, but poor tribological properties. However, these can be enhanced by nitriding processes.
