摘要： [Problem] Provided are a metal material including a passive film on a surface and having corrosion resistance while having a small contact resistance, and a method for producing the metal material. Examples of the metal material include a material that is preferable as a material of a separator and a current collector plate in a fuel cell.
[Solution] Conductive particles 3 are embedded in and caused to adhere to a metal substrate 1 including, on a surface thereof, a passive film 2, in a state where the conductive particles 3 penetrate the passive film 2 in a thickness direction, and the surface of the metal substrate is covered with a coating film having conductivity and corrosion resistance. To cause the conductive particles to adhere in such a manner, the conductive particles 3 may be scattered on the metal substrate 1 on which the passive film 2 is formed, and the conductive particles 3 may be pushed into the surface of the metal substrate 1 by pressing with a roll or the like.-

摘要： A cutting tool has a substrate of cemented carbide including WC and a binder phase. The cutting tool has a gradient surface zone with a thickness of between 50-400 μm having a binder phase gradient with the lowest binder phase content in the outermost part of the gradient surface zone and wherein the cutting tool also includes free graphite. The present disclosure also relates to a method of making a cutting tool according to the above. The cemented carbide body shows improved resistance towards chemical wear when used for machining non-ferrous alloys such as Ti-alloys and Ni-based alloys.

摘要： A rechargeable lithium-ion (Li-ion) battery employs a solvent-less, low temperature approach to battery manufacturing that forms charge material from kinetic energy of high velocity particles impelled into an aggregation such that bombardment of the particles against other particles in the aggregation forms a charge conveying structure. High velocity bombardment from a carrier gas nozzle accumulates an active charge material (active material) and metal binder in a layered arrangement for the finished battery. Preparation of the particles, such as by ball milling or freeze drying, arranges particle agglomerations. The particle agglomerations, when impelled against other agglomerations or a current collector, forms a layer of cathodic, anodic or electrolytic battery material. The metallic binder conveys charge for mitigating or eliminating a need for a planar current collector underlying the sprayed layer. The resulting layers are suitable for battery operation, and are manufactured in an absence of any solvent drying or disposal.

摘要： The present invention relates to tooling and methods for disposing, coating, building up, repairing, or otherwise modifying the surface of a metal substrate using frictional heating and compressive loading of a consumable metal material against the substrate. Embodiments of the invention include friction-based fabrication tooling comprising a non-consumable member with a throat and a consumable member disposed in the throat, wherein the throat is operably configured such that during rotation of the non-consumable member at a selected speed, the throat exerts normal forces on and rotates the consumable member at the selected speed; and comprising means for dispensing the consumable member through the throat and onto a substrate using frictional heating and compressive loading. Embodiments of the invention also include fabrication methods using the tools described herein.
