In this research work, the influence of higher surface hardness on the fretting fatigue life of hard anodized aerospace AL7075-T6 alloy was investigated. An optimization of the parameters of hard anodized Al7075-T6 alloy to obtain higher surface hardness was presented. Confirmation test was carried out to show the improvement after using the best parameter combination attained from the optimiza...

Copper alloys are widely used in the manufacturing of heat transfer applications, this due to their excellent heat transfer properties. Copper contamination is one of the serious industrial problems in the boiler feed water system. This contamination commonly resulted from copper corrosion reactions in boiler feed water environment. The best way to reduce the copper contamination is by improvin...

BACKGROUND Titanium (Ti) implants are widely used clinically, but peri-implantitis remains one of the most common and serious complications. Healthy integration between gingival tissue and the implant surface is critical to long-term success in dental implant therapy. The objective of this study was to investigate how different concentrations of immobilized fibroblast growth factor 2 (FGF2) on ...

Illumination affects corrosion of oxide-covered metals via photoinitiated dissolution processes. Herein, anodized titanium with n-type semiconducting anatase TiO2 and copper p-type cuprite Cu2O thicknesses up to ≈90 nm are prepared, investigated under controlled convection in photoelectrochemical experiments illuminated at grazing incidence. photon energies above the bandgap triggers anodic pho...

PURPOSE The aim of this study was to investigate the combined effects of physical and chemical surface factors on in vivo bone responses by comparing chemically modified hydrophilic sandblasted, large-grit, acid-etched (modSLA) and anodically oxidized hydrophobic implant surfaces. METHODS Five modSLA implants and five anodized implants were inserted into the tibiae of five New Zealand white r...
