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 کاملNext Generation Coatings for Erosion-Corrosion Protection Sprayable protection in extreme erosion environments
The erosion-corrosion environments found in fluid conveying components such as pipelines, pumps, agitators and chutes have important implications for both service life and maintenance cost. The destructive synergy wrought when corrosion occurs in combination with erosion can be many times greater than the sum of each mechanism acting in isolation. A factory applied coating, if present, will hav...
