Abstract:
A timepiece part includes: a substrate; and a first coating configured from a material containing cobalt as a primary component, and 26 mass% to 30 mass% of Cr, and 5 mass% to 7 mass% of Mo. The first coating has an average signal intensity of oxygen of 0 counts/sec to 150 counts/sec as measured by SIMS relative to a 1.0 µm-thick reference film of a composition containing Co: 62.8 mass%, Cr: 28.2 mass%, Mo: 6.0 mass%, C: 1.5 mass%, and Ar: 1.5 mass%.
Abstract:
The present invention relates to a method for producing a layer (2) of aluminum oxide and/or aluminum nitride (Al2O3, or AIN) on a substrate (1), said method comprising a sequence of consecutive steps a) and b) according to which: a) a basic layer of aluminum (21, 22) having a thickness between 5 and 25 nm is deposited on the substrate (1) in a deposition chamber (10), b) the substrate (1) is moved into a treatment chamber (20) separate from the deposition chamber (10), in which the basic layer of aluminum (21, 22) is oxidized or nitrided to produce a basic layer of aluminum oxide or aluminum nitride (21' 22'). Said sequence of consecutive steps is repeated in a loop until said layer of aluminum oxide and/or aluminum nitride (2) is obtained by stacking the consecutive layers of aluminum oxide and aluminum nitride (21' 22').
Abstract:
A bio control surface (100) comprising a substrate (5) and a first plurality of discrete, spaced-apart particles (1) disposed on the substrate (5) and a second plurality of discrete, spaced-apart particles (6) disposed on the substrate (5), wherein the first (1) and second (6) pluralities of discrete, spaced-apart particles are formed from species having different chemical and/or electrical properties. An intermediate layer (4) may be interposed between the particles (1, 6) and the substrate (5). The bio control surface (100) can be activated by exposure to particular conditions, which cause the first (1) and second (6) pluralities of particles to adopt different potentials (+, −), such that flow of charge, heat, ions etc. can be used to neutralise or kill bacteria or microorganisms resident on the surface (100).
Abstract:
A chemically converted steel sheet having a chemically converted coating film is made by coating a Zn-based plated steel sheet with a chemical conversion treatment solution and drying the same. The chemically converted coating film is constituted by a first chemically converted layer including V, Mo, and P, and a second chemically converted layer provided on said layer and including a group 4A metal oxygen acid salt, and the ratio of pentavalent V to all the Vs in the chemically converted coating film is 0.7 or greater. The chemical conversion treatment solution includes specific proportions of V, Mo, an amine, the group 4A metal oxygen acid salt, and P, and substantially does not include hydrophilic resins, fluorine, or silicon.
Abstract:
A method of manufacturing three-dimensional thin-film nitinol (NiTi) devices includes: depositing multiple layers of nitinol and sacrificial material on a substrate. A three-dimensional thin-film nitinol device may include a first layer of nitinol and a second layer of nitinol bonded to the first layer at an area masked and not covered by the sacrificial material during deposition of the second layer.
Abstract:
A composite coating for a metal forming member includes a first layer disposed on said metal forming member. The first layer includes chromium nitride doped with at least one dopant such as tungsten. A second layer is disposed atop said first layer, said second layer including a lubricious material having a coefficient of friction of less than or equal to 0.2 as measured against low alloy steel.
Abstract:
Provided are a three-dimensional net-like aluminum porous body in which the diameter of cells in the porous body is uneven in the thickness direction of the porous body; a current collector and an electrode each using the aluminum porous body; and methods for producing these members. The porous body is a three-dimensional net-like aluminum porous body in a sheet form, for a current collector, in which the diameter of cells in the porous body is uneven in the thickness direction of the porous body. When a cross section in the thickness direction of the three-dimensional net-like aluminum porous body is divided into three regions of a region 1, a region 2 and a region 3 in this order, the average cell diameter of the regions 1 and 3 is preferably different from the cell diameter of the region 2.
