Solid particle erosion is an important material degradation mechanism. Although various methods of coating are tried and used for protection against erosion, thermal sprayed coating for such purpose is the most widely used method. In this chapter, evolution of thermal sprayed coating, erosion testing methods, and erosive wear of thermal sprayed coatings are discussed extensively with emphasis o...

â increase in wastage of soil resources in watershed is a persistent challenge that with increase in population and pressure on natural sources and unstable plantation on gradient farms and soils cause production reduces on farms, and also decrease in daily ratio of farms to population can cause more pressure on lands and natural resources.lavarefin watershed placed in 60 km from bandarabass in...

AIM To investigate any association between dental erosion and its potential dietary risk factors in a group of schoolchildren in Benghazi, Libya. STUDY DESIGN A cross-sectional observational study. METHODS A random sample of 12-year-old schoolchildren in 36 randomly selected schools completed a questionnaire to provide dietary data and underwent dental examination. Dental erosion was assess...

This article developed an ion thruster optic system sputter erosion depth numerical 3D model by IFE-PIC (Immersed Finite Element-Particle-in-Cell) and Mont Carlo method, and calculated the downstream surface sputter erosion rate of accelerator grid; compared with LIPS-200 life test data. The results of the numerical model are in reasonable agreement with the measured data. Finally, we predicted...

the result of wind dynamic (capacity and potential) is transport of soil or sediment particles and subsequent formative desert landforms based on the severity of erosion or sedimentation. the khartouran region, because of its geology, geomorphology and climatology conditions is a special place in the arid region on the closed basin of dasht-e-kavir. it is evident that the ecosystem balance of t...

Modeling of erosion and deposition in complex terrain within a geographic information system (GIS) requires a high resolution digital elevation model (DEM), reliable estimation of topographic parameters, and formulation of erosion models adequate for digital representation of spatially distributed parameters. Regularized spline with tension was integrated within a GIS for computation of DEMs an...

It is highly likely that coastal erosion due to long-term sea level rise associated with global warming will have a significant impact on Australia’s coastal systems, and any associated infrastructure, over the next century. Long-term coastal erosion is thought to occur largely through sudden-onset storm events. Therefore, attempting to quantify this natural hazard is critical to future develop...
