Embodiments of the invention relate to polycrystalline diamond compacts (PDCs) and methods of fabricating polycrystalline diamond tables and PDCs in a manner that facilitates removal of metal-solvent catalyst used in the manufacture of polycrystalline diamond tables of such PDCs.

A sliding member having a hardness proper for an environment where a high-pressure is applied and having a good abrasion resistance. A sliding member 1 comprises a first sintered compact layer 2 formed by solidifying an iron-based metallic powder with a sinter; and a second sintered compact layer 3 formed by solidifying a copper-based metallic powder on a surface of the first sintered compact layer 2 to improve a sliding characteristic. The second sintered compact layer 3 is densified by a blast process where the powder is collided against a surface of the second sintered compact layer 3.

Mixed powder that contains first hard particles, second hard particles, graphite particles, and iron particles is used to manufacture a sintered alloy. The first hard particle is a FeMoCrMn based alloy particle, the second hard particle is a FeMoSi based alloy particle. The mixed powder contains 5 to 50 mass % of the first hard particles, 1 to 8 mass % of the second hard particles, and 0.5 to 1.0 mass % of the graphite particles when total mass of the first hard particles, the second hard particles, the graphite particles, and the iron particles is set as 100 mass %.

The solder composition comprises particles of a thermodynamically metastable alloy. One of the elements of the alloy will form an intermetallic compound with a metal surface. The solder composition is particularly suitable for use in bumping of semiconductor devices.

The present invention discloses a novel and inventive transparent conductive film Differing from conventional metal mesh substrates are mainly constituted by silver nanowires (AgNW), the present invention particularly designs a nano metal wire consisting of a metallic core wire, a transition layer and a protection layer, and further develops a transparent conductive film consisting of a substrate and a metal mesh layer; wherein the metal mesh layer is constituted by the said nano metal wires. It is worth describing that, a variety of experimental data prove that the thermal resistance of this novel transparent conductive film is up to 400 C.; moreover, experimental data also exhibit that the transparent conductive film can filter part of blue light portion out of a white light by 20-30%.

Red rust staining of Al/Zn coated steel strip in acid rain or polluted environments can be minimised by forming the coating as an AlZnSiMg alloy coating with an OT:SDAS ratio greater than a value of 0.5:1, where OT is the overlay thickness on a surface of the strip and SDAS is the measure of the secondary dendrite arm spacing for the Al-rich alpha phase dendrites in the coating. Red rust staining in acid rain or polluted environments and corrosion at cut edges in marine environments can be minimised in AlZnSiMg alloy coatings on steel strip by selection of the composition (principally Mg and Si) and solidification control (principally by cooling rate) and forming Mg.sub.2Si phase particles of a particular morphology in interdendritic channels.

A powder metal compact is disclosed. The powder metal compact comprises a cellular nanomatrix comprising a metallic nanomatrix material. The powder metal compact also comprises a plurality of dispersed particles comprising a metallic particle core material dispersed in the cellular nanomatrix, the particle core material comprising a nanostructured material.

A method for applying a protective layer to protect against an impact stress includes mixing a sealing alloy in a powder form with a binder and water to form a pasty compound, applying the pasty compound on a surface to be protected, drying the applied pasty compound, and heating the dried applied pasty compound to a temperature of at least 800 C.

A system includes a layered structure. The layered structure includes first and second coalesced layers and an intermediate layer disposed between the first and second coalesced layers. The first and second coalesced layers have a higher degree of coalescence than the intermediate layer.
