Erosion-corrosion and wear
The basic processes of wear, erosion and erosion-corrosion are reviewed. It is shown that oxide debris can accelerate wear when it is present as particulates, or protect and reduce friction when it is present as a glaze. Erosion-corrosion processes can be understood and organized in a series of regimes that represent a sequence of change in the relative intensities of erosive and corrosive proc...
متن کاملAnimating Corrosion and Erosion
In this paper, we present a simple method for animating natural phenomena such as erosion, sedimentation, and acidic corrosion. We discretize the appropriate physical or chemical equations using finite differences, and we use the results to modify the shape of a solid body. We remove mass from an object by treating its surface as a level set and advecting it inward, and we deposit the chemical ...
متن کاملErosion, Corrosion and Erosion-Corrosion of EB PVD Thermal Barrier Coatings
Electron beam (EB) physical vapour deposited (PVD) thermal barrier coatings (TBCs) have been used in gas turbine engines for a number of years. The primary mode of failure is attributed to oxidation of the bondcoat and growth of the thermally grown oxide (TGO), the alumina scale that forms on the bondcoat and to which the ceramic top coat adheres. Once the TGO reaches a critical thickness the T...
متن کاملIX. INHIBITOR EFFECTIVENESS ON CO2 CORROSION WITH SAND Introduction Erosion, corrosion, and erosion-corrosion are common problems in offshore
Erosion, corrosion, and erosion-corrosion are common problems in offshore pipelines, tubing and pipe fittings. Corrosion has an important impact on the total cost of oil and gas production. Considering the diversity of corrosion related problems, CO2 corrosion (sweet corrosion) is probably the material degradation mechanism most extensively assessed in this industry over the last 30 years. In t...
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...
