Influence of thermal treatments in the corrosion behaviour of HVOF Cr 3C2-NiCr coatings
(2001-12-01)
Thermal spray coatings as Cr3C2-NiCr obtained by high velocity oxy-fuel spraying (HVOF) are mainly applied due to their behaviour against aggressive erosive-abrasive and corrosive atmospheres and their thermal stability ...
Effect of acid hydrolysis conditions on the degradation properties of cellulose from Imperata brasiliensis fibers
(2017-01-01)
The thermal properties of Imperata brasiliensis fibers and cellulose nanofibrils (CNFs), obtained at different conditions of sulfuric acid hydrolysis, were studied in the present work. Imperata Brasiliensis fibers were ...
Some properties of the Riemannian distance function and the position vector X, with applications to the construction of Lyapunov functions
(Ieee, 2010-01-01)
The quadratic distance function on a Riemannian manifold can be expressed in terms of the position vector, which in turn can be constructed using geodesic normal coordinates through consideration of the exponential map. ...
MgAl2O4-ZrO2(Y2O3) ceramic composite: Sintering and characterization
(2017-01-01)
Spinel is a ceramic material of excellent translucence when sintered in high densification, however, its low sinterability and toughness difficulty limit its use as an interesting material for dental applications. The use ...
