Abstract: An environmentally resistant coating comprising silicon, titanium, chromium, and a balance of niobium and molybdenum for turbine components formed from molybdenum silicide-based composites. The turbine component may further include a thermal barrier coating disposed upon an outer surface of the environmentally resistant coating comprising zirconia, stabilized zirconia, zircon, mullite, and combinations thereof. The molybdenum silicide-based composite turbine component coated with the environmentally resistant coating and thermal barrier coating is resistant to oxidation at temperatures in the range from about 2000null F. to about 2600null F. and to pesting at temperatures in the range from about 1000null F. to about 1800null F.

Abstract: An elastomeric-based device configured for use in high temperature downhole environments exceeding about 400° F. The device includes a carbon nanotube mesh configured to dissipate heat relative elastomeric portions thereof so as to provide temperature resistance. Thus, a majority of modulus strength of the elastomeric portions may be maintained along with device functionality even upon exposure to such temperatures. Further, the mesh may also be configured to mimic the modulus character of elastomeric portions to allow a cohesive compliance to the device as a whole. Thus, isolation packers and other expansive downhole devices may particularly benefit from such combined material configurations as detailed herein.

Abstract translation: 一种被配置用于超过约400°F的高温井下环境中的基于弹性体的装置。该装置包括碳纳米管网，其被配置为散发热相对弹性体部分以便提供耐温性。 因此，即使暴露在这样​​的温度下，弹性体部分的大部分模量强度也可以与器件功能一起保持。 此外，网格还可以被配置为模拟弹性体部分的模数特征，以允许整体上与装置的内聚性一致。 因此，隔离封隔器和其它膨胀的井下装置可能特别受益于如本文详细描述的这种组合的材料构造。

Abstract: A turbocharger for an internal combustion engine, in which a bearing having excellent abrasion resistance without generating a black corrosion product in a high-temperature oil environment is provided. As bearing materials of a turbocharger, a copper alloy material containing, as main components, Cu, Zn, Al, Mn, and Si is employed. The elongating direction of an Mn—Si compound crystallized in the alloy material is set to the axial direction of a rotary shaft with respect to a radial bearing and is set to the direction perpendicular to the rotary shaft with respect to a thrust bearing.
