Abstract In aircraft and storage fuel tanks, many environmental corrosion factors can be present, which cause breakdown to the passive film of aluminum causing severe localized corrosion. Aiming a solution this problem, diamond‐like carbon (DLC) films were deposited on substrates Al 2024‐T3, 5052‐H32, 6061‐T6. The with without DLC submitted corrosive immersion test aviation Jet‐A1 AVGAS 100LL. surface morphology from was analyzed before after 7 30 days tests by SEM. adhesion evaluated...
Titanium dioxide (TiO2) thin films are widely used in transparent optoelectronic devices due to their excellent properties, as well photocatalysis, cosmetics, and many other biomedical applications. In this work, TiO2 were deposited onto AISI 304 316L stainless steel substrates by atomic layer deposition, followed comparative evaluation of the mixture anatase rutile phase X-ray diffraction, Raman maps, morphology SEM-FEG-AFM, adhesion on two substrates, aiming evaluate scratch resistance....
Abstract Polyurethane (PU) substrates are biocompatible materials widely used to manufacture endotracheal tubes. However, in common with other biomedical materials, they liable the formation of microbial films. The occurrence pneumonia intubated patients treated at intensive care units often takes form ventilator-associated (VAP). issue relates translocation pathogenic microorganisms that colonize oropharyngeal mucosa, dental plaque, stomach, and sinuses. New protective can provide a more...
Titanium dioxide (TiO2) thin films have been widely used in transparent optoelectronic devices owing to their excellent optical properties also is photocatalysis, cosmetics, and many other biomedical applications. However, a lack of studies was published on microstructure adherence comparison the TiO2 deposited both AISI substrates. In this work, were onto 304 316L stainless steel (SS) substrates via atomic layer deposition. Its heterostructure, morphology, adhesion compared looking for...
Bacterial contamination in hospital environments is a significant concern for patient admissions. Aiming to reduce contamination, titanium dioxide film (TiO 2 ) the anatase phase has been prepared on surface of polyvinyl chloride (PVC) tubes. The PVC tube material was used study film’s effectiveness inhibiting bacterial growth and cell viability. morphology composition deposited films were investigated using Scanning Electron Microscope (SEM) Energy Dispersive Spectroscopy (EDS) map. In...
Revestimentos de filmes carbonosos são estudados para reduzir desgaste e aumentar biocompatibilidade, condutividade elétrica ou a aderência metais, dentre as diversas técnicas deposição há por laser pulsado (PLD) que é uma técnica rápida eficaz deposição. O dióxido titânio (TiO2) um material cerâmico apresenta inúmeras possibilidades aplicação, tais como sua eficiência na destruição inibição microrganismos. objetivo deste trabalho foi o estudo depositados pela PLD sobre liga Ti-6Al-4V, muito...
