  • Patent number: 10865476
    Abstract: CVD Alumina coating has been one of the most important materials for wear resistant application for many years. Recently, texture control in ?-Al2O3 has attracted increasing attention due to the possibility to further improve the anisotropic properties such as thermal conductivity and mechanical properties. The influence of process parameters on textures is complex. In the present application, the influence of nucleation surface condition and H2S on the texture in CVD ?-Al2O3 coatings has been investigated. It has been shown that without the addition of H2S, the crystal orientation in the Al2O3 coatings is primarily dominated by the nucleation surface condition, whereas the effect of reactant composition on texture is minimal. On the other hand, in the presence of H2S during growth, reactant composition also plays an important role in affecting the crystal orientation. This effect is likely due to the strong interaction between the Al2O3 surface and the H2S.

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: 8899949
    Abstract: A refrigerant compressor includes a compression unit having a roller and a vane for compressing refrigerant. The vane has a film having first to fourth layers on its metallic base member. The first layer is made of chromium. The second layer is made of chromium and tungsten-carbide. The third layer is made of metal-containing amorphous-carbon containing at least tungsten or tungsten-carbide. The fourth layer is made of non-metal-containing amorphous-carbon containing carbon and hydrogen. In the second layer, chromium content-rate on a first-layer side is larger than on a third-layer side, and tungsten-carbide content-rate on the third-layer side is larger than on the first-layer side. In the third layer, content-rate of the at least tungsten or tungsten-carbide on a second-layer side is larger than on a fourth-layer side. The roller with which an end-edge of the vane slidably-contacts is made of flake graphite cast iron containing molybdenum, nickel and chromium.

  • 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.
