  • Publication number: 20130052437
    Abstract: Components with improved erosion resistance are disclosed. A surface of the component or a substrate of the component is modified by coating the substrate with an elastomer layer. The elastomer layer is then modified by embedding hard particles onto an outer side of the elastomer layer. The hard particles exhibit higher fractured toughness providing enhanced erosion protection. The elastic properties of the elastomer experience little reduction because the surface embedded particles are located only at the outer side or outer surface of the elastomer layer. Therefore, the bond between the inner side of the elastomer layer and the substrate or component surface is not interfered with and the potential for electro-chemical corrosion and poor adhesion are not increased by the presence of the hard particles as the hard particles are located away from the inner face between the elastomer layer and the substrate.

  • Patent number: 7041378
    Abstract: A heating system employs a ceramic substrate and a resistive layer. The resistive layer includes a thermally stable resin, which is filled with a conductive material. A method of manufacturing such a heating system involves a provision of a ceramic substrate and an application of a resistive layer on the substrate. In the method, the resistive layer comprises includes a thermally stable resin, which is filled with a conductive material. Before application of the resistive layer, an adhesion promotor is applied on the ceramic substrate.
