  • Publication number: 20180016194
    Abstract: Disclosed is a method for producing a carbide derived carbon layer with a dimple pattern. The method includes forming a dimple pattern on the surface of a carbide ceramic material and forming a carbide derived carbon layer thereon. Also disclosed is a carbide derived carbon layer with a dimple pattern produced by the method. The carbide derived carbon layer with dimple pattern has high wear resistance, good adhesion to a machine part, and excellent frictional characteristics. The carbide derived carbon layer can be applied to various fields, such as coating of carbide coated and carbide materials. Particularly, the carbide derived carbon layer is suitable for coating of machine parts (e.g., sliding parts, mechanical seals, piston rings, and compressor vanes) where excellent mechanical properties are needed.

  • Publication number: 20160257584
    Abstract: A slow-release method for treating non-point source pollutants traveling in water runoff, such as urban water runoff. Method embodiments include the use of slow-release advanced oxidation process forms (SR-AOPs) comprised of one or more water soluble salts in a matrix and/or forms producing hydrogen peroxide, persulfate anion, and/or permanganate. One or more of such forms may be placed along with one or more slow-release iron forms in the path of runoff water as it flows through a storm sewer system, such that an amount of the water soluble salt(s) and/or hydroxyl radicals (Fenton's reagent), persulfate radicals, or permanganate are slowly released into the runoff water to oxidize the pollutants contained therein.
