  • Patent number: 9957590
    Abstract: A new pre-alloyed metal based powder, intended to be used in surface coating of metal parts. The powder is deposited using e.g. laser cladding or plasma transfer arc welding (PTA), or thermal spray (e.g. HVOF). The powder is useful for reducing friction and improving wear reducing properties of the deposited coating. Such coatings may also improve machinability. As friction or wear reducing component, inclusions of manganese sulphide or tungsten sulphide in the pre-alloyed powder may be used.

    Abstract: A class of nickel based alloys having a fine grain structure resistant to stress corrosion cracking, and methods of alloy design to produce further alloys within the class are presented. The alloys act as suitable welding materials in similar applications to that of Alloy 622. The fine-grained structure of these novel alloys may also be advantageous for other reasons as well such as wear, impact, abrasion, corrosion, etc. These alloys have similar phases to Alloy 622 in that they are composed primarily of austenitic nickel, however the phase morphology is a much finer grained structure opposed to the long dendritic grains common to Alloy 622 when it is subject to cooling rates from a liquid state inherent to the welding process.

In order to obtain adherence between the coating and the surfaces of the former, one or more thin ghost coat layers of slurry are applied to the surface of the graphite former before one or more layers of normal strength slurry are applied. Each layer of coating is allowed to dry before the next layer is applied, and the former may be heated to dry each layer. Pressed components of length greater than 2m can be processed, relative contraction of the component and former during cooling of the component being accommodated by the boron nitride coating on the former.

  • Patent number: 7381369
    Abstract: Provided is free cutting alloy excellent in machinability, preserving various characteristics as alloy. The free cutting alloy contains: one or more of Ti and Zr as a metal element component; and C being an indispensable element as a bonding component with the metal element component, wherein a (Ti,Zr) based compound including one or more of S, Se and Te is formed in a matrix metal phase. The free cutting alloy is more excellent in machinability, preserving various characteristics as alloy at similar levels to a conventional case. The effect is especially conspicuous, for example, when a compound expressed in a chemical form of (Ti,Zr)4C2(S,Se,Te)2 as the (Ti,Zr) based compound is formed at least in a dispersed state in the alloy structure.

  • Patent number: 7118636
    Abstract: An Fe—Ni—Cr alloy formulated to contain a strengthening phase that is able to maintain a fine grain structure during forging and high temperature processing of the alloy. The alloy contains a sufficient amount of titanium, zirconium, carbon and nitrogen so that fine titanium and zirconium carbonitride precipitates formed thereby are near their solubility limit in the alloy when molten. In the production of an article from such an alloy by thermomechanical processing, a dispersion of the fine titanium and zirconium carbonitride precipitates form during solidification of the melt and remain present during subsequent elevated processing steps to prohibit austenitic grain growth.

  • Patent number: 6858178
    Abstract: A composition of a porous body for use as biomaterial according to the present invention is produced by adding Al (aluminum) in the amount of 0.1 to 3.0 atomic % to a porous composition consisting of titanium, nickel, iron and molybdenum, and it promotes the growth of living tissue and cells into pores. By the addition of Al to Ni, Ti, Fe and Mo, the temperature of formation of the liquid phase is lowered, and thus the diffusion of the constitutional elements of the composition is promoted, and the uniform distribution of the constitutional elements increases. As a result, the proportion of micropores in the porous body becomes increased to the extent that the distribution of micropores having the size in the range of 10?2 ?m˜10 ?m is more than 5% in the metal bridge.

  • Patent number: 6677019
    Abstract: A paperboard tube is rendered resistant to liquid by coating portions or all of the tube with submicron-sized particles of inorganic material that are treated to be hydrophobic and/or oleophobic. The particles can be applied directly to the paperboard, lodging in surface pores such that the particles adhere to the paperboard. Alternatively, a light coating of a tacky binder or adhesive can first be applied to the paperboard and then the particles can be applied such that they adhere to the binder. Preferably, the particles have a large surface area per gram; in one embodiment, for instance, silica particles are employed having a surface area of about 90-130 m2/g. As a result, the particles create a surface on the paperboard that is highly repellant to liquid.
