    Abstract: A reflective optical component is configured to reflect EUV radiation. The reflective optical component has a reflective layer with a bimetal cap layer of differing first and second metals selected to ensure that the outer surface of the cap layer is substantially unreactive or non-adsorptive to sulfur. The bimetal cap layer may be an alloy of the two metals or may consist of a base layer of the first metal deposited on the reflective layer and a surface layer of the second metal on the base layer. The interaction of the two metals may lead to modification of the bonding energy to the outer face of the cap layer of sulfur-containing molecules such as SO2 so that sulfur adsorption, which leads to loss of reflectivity, is reduced or eliminated.

  • Patent number: 8808871
    Abstract: A sintered cermet of a rotary tool has a hard phase with a first hard phase and a second hard phase comprising a carbide, a nitride, and a carbonitride of at least one of group 4, 5, and 6 metals of the periodic table of which metals the metal titanium is a main component. The result of an X-ray diffraction measurement in a surface region of the sintered cermet provides a first peak intensity Ib on a high angle side that is attributable to a (220) plane of the first hard phase and a second peak intensity Ia on a low-angle side that is attributable to a (220) plane of the second hard phase, and an intensity ratio Ib/Ia of the first peak intensity Ib to the second peak intensity Ia is in the range of 0.5 to 1.5.

  • Patent number: 8795845
    Abstract: Methods for the low-temperature synthesis of an integrated, corrosion-resistant coating structure for metal substrates by means of multi-component pack cementation are provided. The synthesis of the integrated coating structures at low temperatures can avoid or minimize degradation of the mechanical properties of the substrates. The integrated coating structures can increase the lifetime of high temperature steels under severe steam environments and, therefore, provide a technological enabler for the high-temperature operation of steam power generation plants.

  • Publication number: 20140208929
    Abstract: A durable ceramic and metallic coating has been applied to ceramic tiles to protect the tiles while undergoing a molten metal casting operation. The plasma sprayed coating consists of a ceramic top coat layer of aluminum oxide, zirconium oxide, or other oxides with or without a metallic bond coat layer and with or without a functionally gradient coating. This coating protects the underlying ceramic tile, which is composed of boron carbide, silicon carbide, alumina (Al2O3) or other type of hard ceramic, from reacting chemically with the molten metal. The molten metal is cast around the ceramic tiles to create a lattice of ceramic tiles that are used for protection from projectiles and shrapnel.

  • Patent number: 8673455
    Abstract: A coating steel component with a pattern of an iron based matrix with crystalline particles metallurgically bound to the surface of a steel substrate for use as disc cutters or other components with one or more abrading surfaces that can experience significant abrasive wear, high point loads, and large shear stresses during use. The coated component contains a pattern of features in the shape of freckles or stripes that are laser formed and fused to the steel substrate. The features can display an inner core that is harder than the steel substrate but generally softer than the matrix surrounding the core, providing toughness and wear resistance to the features. The features result from processing an amorphous alloy where the resulting matrix can be amorphous, partially devitrified or fully devitrified.
