A method for manufacturing electrodes for storage battery cells, wherein a material web is coated at least on a first side with a coating material, and the coating material is deposited on the first side using a first application roller.

The disclosure relates to a method of conducting a coiled tubing operation. In one implementation, a method includes forming a tubing string, the tubing string having an outer surface. The method also includes applying a coating to an application portion of the outer surface of the tubing string. The application portion includes a portion of the tubing string that will be disposed in a horizontal section of a wellbore, and the coating has a surface energy lower than a surface energy of the outer surface of the tubing string to thereby reduce friction between the tubing string and a casing disposed in the horizontal section of the wellbore as the tubing string is lowered into the wellbore.

A method is disclosed for manufacturing a blade tip coating. The blade tip coating (152) comprising an abrasive (156) and a matrix (154). The method comprises forming a mixture comprising the abrasive, a precursor of the matrix, and an additional particulate (158). The mixture is pressed, the additional particulate acting as a stop to limit thickness reduction of the mixture.

Methods of manufacturing an extrusion die (100) having a plurality of pins (600a-c) and a plurality of slots (601) defined by the plurality of pins, each pin having a base, the method including applying a coating material (604) over side walls of the bases of the pins of the extrusion die and removing a portion of the coating material coated over the side walls of the bases of the plurality of pins with a cutting tool (650). In some embodiments, the cutting tool has a cutting width (652) equal to a target slot width (640) of the slots. In some embodiments, applying the coating material over the side walls of the bases of the pins includes overcoating a coating material to a thickness that is greater than a thickness needed to define a target slot width of the slots.

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.

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 m 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.

A method for producing nozzles for injectors of internal combustion engines comprising machining nozzle blanks, each having a cylindrical surface with first and second ends, a flat reference surface at the first end and a nozzle tip projecting from the second end, applying a protective disc onto each flat reference surface, providing a containment tube with a closed first end, sequentially inserting the nozzle blanks into the containment tube and completely filling a space delimited from an outer surface of the nozzle tip of the respective nozzle blank to an inner wall of the containment tube after each insertion, compacting the metal powder, evacuating a second end of the containment tube, hot isostatic pressing the containment tube, cutting the containment tube along cutting sections aligned with the protective discs to form separate sections, and machining the sections to form a metallic coating on each nozzle tip.
