A Review of the Erosion of Thermal Barrier Coatings. [PDF]

open access: yes, 2007
The application of thermal barrier coatings (TBCs) to components with internal cooling in the hot gas stream of gas turbine engines has facilitated a steep increase in the turbine entry temperature and the associated increase in performance and ...

Vertical mineralization interval and forecast of the position of an ore-body in the Alšar Sb-As-Tl deposit, FYR Macedonia [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2011
Establishing a vertical interval of mineralization is a complex geological task based on the knowledge of many parameters and quantities that describe the genesis of an ore deposit.

Estimation of Apollo lunar dust transport using optical extinction measurements [PDF]

open access: yes, 2015
A technique to estimate mass erosion rate of surface soil during landing of the Apollo Lunar Module (LM) and total mass ejected due to the rocket plume interaction is proposed and tested.

Effect of microstructure and temperature on the erosion rates and mechanisms of modified EB PVD TBCs [PDF]

open access: yes, 2009
Thermal barrier coatings (TBCs) have now been used in gas turbine engines for a number of decades and are now considered to be an accepted technology. As there is a constant drive to increase the turbine entry temperature, in order to increase engine ...

Solid particle erosion and viscoelastic properties of thermoplastic polyurethanes [PDF]

open access: yes, 2015
The wear resistance of several thermoplastic polyurethanes (TPUs) having different chemical nature and micronscale arrangement of the hard and soft segments has been investigated by means of erosion and abrasion tests.

Geomorphological Mapping and Erosion of Abandoned Tailings in the Hiendelaencina Mining District (Spain) from Aerial Imagery and LiDAR Data

open access: yesRemote Sensing, 2022
The Hiendelaencina district in Spain was the most important silver producer in Europe during 1844–1925. At the end of the 20th century, with mines having closed, some waste rock dumps were reprocessed, and the sludge from the flotation process was stored

Rates of erosion and landscape change along the Blue Ridge escarpment, southern Appalachian Mountains, estimated from in situ cosmogenic 10Be [PDF]

open access: yes, 2016
The Blue Ridge escarpment, located within the southern Appalachian Mountains of Virginia and North Carolina, forms a distinct, steep boundary between the lower-elevation Piedmont and higher-elevation Blue Ridge physiographic provinces.

Effect of Nanosilica on Bending Strength and Thermal Stability of Glass Fiber/Phenolic Nanocomposite [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2016
Glass fiber/phenolic composites are effectively used as heat shields for fabrication of cooled combustion chambers. To improve the performance of these composites as well as to lower their costs, the use of nanosized silicon dioxide (SiO2) particles has ...

The significance of velocity exponents in identifying erosion-corrosion mechanisms [PDF]

open access: yes, 1993
The modes of erosion-corrosion are diverse and may vary from being ''erosion-dominated'', where erosion of metal is the dominant process, to ''corrosion-dominated'', where erosion of oxide scale is the dominant process.

Rock Abundance and Erosion Rate at the Zhurong Landing Site in Southern Utopia Planitia on Mars

open access: yesEarth and Space Science, 2022
Rocks on the Martian surface exhibit signatures of geological activities. Rock distribution is also an important factor for landing site selection for exploration missions.
