Effect of Porosity on Cavitation Erosion Resistance of HVOF Processed Tungsten Carbide Coatings
The phenomenon of cavitation is widely experienced in both pumps and under-water components of hydro power plants. The mechanism of material damage during cavitation is mainly attributed to implosion of high velocity bubbles on to the surface giving raise to local increase in stresses in excess of 1.4 GPa. In addition, material wastage due to particle induced erosion is observed in hydro plants...
متن کاملComparison of cavitation erosion rate with liquid impingement erosion rate
Both cavitation erosion and liquid impingement erosion are phenomena that can cause pipe wall thinning in power plants. The Code for Power Generation Facilities, Rules on Pipe Wall Thinning Management, was published by the JSME (Japan Society of Mechanical Engineers) in 2005. The code says that cavitation erosion shall be prevented either in the design stage or by daily inspection. On the other...
متن کاملObservations of cavitation erosion pit formation.
Previous investigations showed that a single cavitation bubble collapse can cause more than one erosion pit (Philipp & Lauterborn [1]). But our preliminary study showed just the opposite - that in some cases a single cavitation pit can result from more than one cavitation event. The present study shows deeper investigation of this phenomenon. An investigation of the erosion effects of ultrasoni...
متن کاملTowards numerical prediction of cavitation erosion.
This paper is intended to provide a potential basis for a numerical prediction of cavitation erosion damage. The proposed method can be divided into two steps. The first step consists in determining the loading conditions due to cavitation bubble collapses. It is shown that individual pits observed on highly polished metallic samples exposed to cavitation for a relatively small time can be cons...
متن کاملCavitation Erosion of Cermet-Coated Aluminium Bronzes
The cavitation erosion resistance of CuAl10Ni5Fe2.5Mn1 following plasma spraying with Al₂O₃·30(Ni20Al) powder and laser re-melting was analyzed in view of possible improvements of the lifetime of components used in hydraulic environments. The cavitation erosion resistance was substantially improved compared with the one of the base material. The thickness of the re-melted layer was in the range...
