摘要： A method is described that can be used in electrodes for electrochemical devices and includes disposing a precious metal on a top surface of a corrosion-resistant metal substrate. The precious metal can be thermally sprayed onto the surface of the corrosion-resistant metal substrate to produce multiple metal splats. The thermal spraying can be based on a salt solution or on a metal particle suspension. A separate bonding process can be used after the metal splats are deposited to enhance the adhesion of the metal splats to the corrosion-resistant metal substrate. The surface area associated with the splats of the precious metal is less than the surface area associated with the top surface of the corrosion-resistant metal substrate. The thermal spraying rate can be controlled to achieve a desired ratio of the surface area of the metal splats to the surface area of the corrosion-resistant metal substrate.

摘要： A method of manufacturing a plurality of R—Fe—B sintered magnets using a plasma flame apparatus and a furnace. The method includes a first step of providing a sintered magnet block. Then, the sintered magnet block is machined to form machined magnets. The method continues with a step of cleaning surfaces of the machined magnets to form cleaned magnets. The method then proceeds with depositing a plurality of spherical droplets of a heavy rare earth powder selected from at least one of Dy or Tb on the surfaces of the cleaned magnets, to produce a plurality of magnets including a uniform film of Dy or Tb. Then, the magnets including the uniform film are sintered to diffuse the uniform film into the magnets through grain boundary phases of the magnets to produce the R—Fe—B sintered magnets. A plasma flame apparatus is also disclosed herein.

摘要： Aspects relate to methods of building Z-graded radiation shielding and covers. In one aspect, the method includes: providing a substrate surface having about medium Z-grade; plasma spraying a first metal having higher Z-grade than the substrate surface; and infusing a polymer layer to form a laminate. In another aspect, the method includes electro/electroless plating a first metal having higher Z-grade than the substrate surface. In other aspects, the invention provides methods of improving an existing electronics enclosure to build a Z-graded radiation shield by applying a temperature controller to at least part of the enclosure and affixing at least one layer of a first metal having higher Z-grade than the enclosure.

摘要： A method of applying a multi-color finish to a plumbing fixture includes depositing a first coating on the plumbing fixture; selectively applying a masking material in a graduated fashion over at least a portion of the first coating to define a gradient from a first portion of the plumbing fixture that is substantially completely covered by the masking material to a second portion of the plumbing fixture that has substantially no masking material; depositing a second coating over the masking material; and removing the masking material from the plumbing fixture such that the plumbing fixture has a surface finish including a transition region representing a gradual transition between the first coating and the second coating.

摘要： In some aspects, this disclosure relates to improved Z-grade materials, such as those used for shielding, systems incorporating such materials, and processes for making such Z-grade materials. In some examples, the Z-grade material includes a diffusion zone including mixed metallic alloy material with both a high atomic number material and a lower atomic number material. In certain examples, a process for making Z-grade material includes combining a high atomic number material and a low atomic number material, and bonding the high atomic number material and the low atomic number together using diffusion bonding. The processes may include vacuum pressing material at an elevated temperature, such as a temperature near a softening or melting point of the low atomic number material. In another aspect, systems such as a vault or an electronic enclosure are disclosed, where one or more surfaces of Z-grade material make up part or all of the vault/enclosure.
