A method and an apparatus for collecting powder samples in real-time in powder bed fusion additive manufacturing may involves an ingester system for in-process collection and characterizations of powder samples. The collection may be performed periodically and uses the results of characterizations for adjustments in the powder bed fusion process. The ingester system of the present disclosure is capable of packaging powder samples collected in real-time into storage containers serving a multitude purposes of audit, process adjustments or actions.

An electron beam installation, which is used for processing powdered material, has a powder container, which can accommodate a powder bed made of the powdered material to be processed. Furthermore, it has an electron beam generator, which is configured to direct an electron beam onto laterally differing locations of the powder bed. To reduce the dispersion of the powdered material during the processing using the electron beam, the electron beam installation has a frit device, which, by applying an AC voltage between at least two electrodes, generates an electromagnetic alternating field, which bonds the powdered material of the powder bed, at least in regions over the powder bed.

An electrode for use in instruments capable of measuring the electrophoretic mobility of particles in solution is disclosed. The electrode is comprised of an inexpensive support member, generally made of titanium, onto a flat surface of which has been connected, generally by microwelding, a flat electrically conductive but chemically inert foil member, preferably platinum. A uniform texture can be generated on the exposed surfaces of the electrode by various means including tumbling the electrode with an abrasive. An oxide layer can be generated on the support member by soaking the composite electrode in an appropriate medium, protecting the exposed surface of the support member from fluid contact with the sample solution, while the foil member, unaffected by the oxidation process, is able to contact the sample solution.

A multi-material component joined by a high entropy alloy is provided, as well as methods of making a multi-material component by joining dissimilar materials with high entropy alloys.

A battery electrode structure includes a substrate, a first conductive layer and a plurality of active particles. The substrate has a substrate surface. The first conductive layer is disposed on the substrate surface. Each of the active particles has a first portion conformally engaged with a surface of the first conductive layer and a second portion protruding outwards from the surface of the first conductive layer.

A method for controlling deformation and precision of a part in parallel during an additive manufacturing process includes steps of: performing additive forming and isomaterial shaping or plastic forming, and simultaneously, performing one or more members selected from a group consisting of isomaterial orthopedic process, subtractive process and finishing process in parallel at a same station, so as to achieve a one-step ultra-short process, high-precision and high-performance additive manufacturing, wherein: performing in parallel at the same station refers to simultaneously implement different processes in a same pass or different passes of different processing layers or a same processing layer when a clamping position of the part to be processed is unchanged. The method can realize the one-step high-precision and high-performance additive manufacturing which has the ultra-short process, has high processing precision, and the parts can be directly applied, so that the method has strong practical application value.

An additive manufacturing assembly includes a substrate, a nozzle for depositing additive material onto the substrate, and at least one cooling nozzle for supplying a cooling fluid to at least a portion of the substrate. The at least one cooling nozzle is movable relative to the substrate. A controller is operably coupled to the cooling nozzle. The controller is programmed to control operation of the at least one cooling nozzle to achieve a desired convection heat transfer coefficient of the additive material.

A method of forming a passage in a turbine component includes: using an additive manufacturing process to form a first support structure on a first surface of the turbine component; forming a second support structure on a second surface of the turbine component, the second support structure being spaced apart from the first support structure; and forming a passage in the turbine component between the first and second support structures.

A turbocharger wheel (4) and shaft (1) assembly exhibits a frustoconical geometry of welding zone contact surfaces extending to the outer circumference of the shaft (1). This frustoconical geometry not only allows continuous centering of the parts (1, 4) during joining, it also eliminates the problem of stress propagation along a plane. The location of the electron beam is shifted so that only the radially outer segment of the frustoconical contact surface is joined by welding, leaving a radially inner unmelted and unfused zone for maintaining firm contact of the oblique surfaces.

An additive manufacturing system including a two-dimensional energy patterning system for imaging a powder bed is disclosed. Improved structure formation, part creation and manipulation, use of multiple additive manufacturing systems, and high throughput manufacturing methods suitable for automated or semi-automated factories are also disclosed.
