Introduction. The ongoing COVID19 pandemic has sorely affected the whole world by hampering the social and economic development in all possible ways. 1 The uncontrolled outbreak of this infectious disease poses a huge threat to the human safety and environment and has raised serious medical concerns. 2,3 This has led to an accelerated development of safety tools (masks, gloves, goggles, .

 ·  · The cyclic hotcorrosion study is carried out on uncoated, conventional coated and nanostructured coated superalloy in the salt environment of Na 2 SO 4 and 60% V 2 O 5 at 900 °C. The weight change measurements are carried out after each cycle to investigate the hot corrosion kinetics of uncoated and coated superalloy using thermo gravimetric technique.

Hot corrosion is one of the main destructive factors against thermal barrier coatings (TBCs) applied on gas turbine hot components. In this study, hot corrosion behavior of conventional bilayer ...

Corrosion can lead to structural failure or loss of containment, costly repairs, lost or contaminated products, environmental damage, risk to personnel, and loss of public confidence. Our corrosion monitoring services continuously focus on your critical equipment, avoiding astrophic failure and maintaining safe and reliable operation.

 · Nanostructured titanium based materials for medical implants: Modeling and development, ... such as joint replacements, mechanical heart valves and dental implants. Although conventional materials technology has resulted in clear improvements in implant performance and longevity, ... From the point of view of corrosion resistance, ...

As shown in Table 1, the fatigue strength of nanostructured CP titanium after one million cycles is about two times higher than that of conventional CP titanium and exceeds that of the Ti–6Al–4V alloy. 15, 25) Considerable improvement of fatigue properties was also shown in the rods from nanostructured Ti Grade 4 produced by ECAPConform and drawing. 13, 24) The high strength of nanoTi ...

Nanostructured diamond produced by chemical vapor deposition (CVD) techniques and composed of nanosize diamond grains have particular promise because of the combination of ultrahigh hardness, improved toughness over conventional microcrystalline .
