Fatigue corrosion cracking of the resulting coating of metal tube .

摘要

Topic The fact that the damage of the further tube occurs from propagation of the crack or formation of the new crack in the metallic conduit which causes the fatigue corrosion crack, is prevented.SolutionsBy the technology of flame spraying, the tube for the boiler of the fatigue corrosion crack is covered, can stop the advance of the particular fatigue crack. Technology of particular flame spraying, compound ones and the chrome which include the nickel, the chrome and boron the empty forms the coating which is selected either inside compound ones which include the base metal, the aluminum, titanium, silicon and the boron which are not included.
