摘要： Abrasive materials for use in abrasive jet systems and associated materials, apparatuses, systems, and methods are disclosed. An abrasive material configured in accordance with a particular embodiment includes abrasive particles individually including an abrasive core and a fluid-repelling coating. The individual abrasive cores can be monolithic and have outer surfaces. The individual fluid-repelling coatings can include an amide wax and/or other suitable materials and can extend around at least about 95% of the outer surfaces of the corresponding abrasive cores. An average sieve diameter of the abrasive particles can be from about 5 microns to about 35 microns. A method for making abrasive materials in accordance with a particular embodiment includes introducing abrasive cores into a mixer, introducing particles of a non-liquid fluid-repelling material into the mixer, introducing an anti-clumping material into the mixer, and mixing the abrasive cores, the fluid-repelling material, and the anti-clumping material.

摘要： Particle-delivery devices, abrasive jet systems, and associated devices, systems, and methods are disclosed herein. In certain aspects, the particle-delivery devices can include an elongated fluidizing chamber and a metering assembly. The metering assembly can include a particle flow path extending from the fluidizing chamber. The metering assembly can also include a carrier-gas passage extending to an injection orifice proximate the fluidizing chamber. The metering assembly can be configured to inject carrier gas into the fluidizing chamber to fluidize particles within the fluidizing chamber. Fluidizing the particles at different carrier-gas pressures and/or flow rates can change the rate of particle delivery. For example, the metering assembly can include a metering opening and a regulator configured to change a steady-state pressure and/or flow rate of carrier gas entering the fluidizing chamber. Systems disclosed herein can include a controller configured to change a flow rate of particles through the metering opening.

摘要： A flash vaporizing liquid jet cutting tool and method for piercing with minimal damage to the cut material. The liquid is preferably superheated water, typically with abrasive particles added after the jet is expressed through a nozzle (abrasive water jet, AWJ) or with abrasive particles added before the jet is expressed through a nozzle (abrasive slurry jet, ASJ). In piercing, only a portion of water that has not changed phase enters into the cavity or must leave the cavity and the piercing pressure, which can damage the material, is therefore reduced.

摘要： An abrasive supply system may, for example, be used to supply abrasive particles such as garnet to a cutting nozzle of an abrasive jet cutter. According to an embodiment, the abrasive is propelled by a substantially constant flow rate gas source. According to an embodiment, the system may be supplied with abrasive from an atmospheric pressure abrasive hopper. According to an embodiment, a controller automatically actuates refilling of an abrasive tank from the abrasive hopper, and then automatically closes an abrasive supply valve and restarts abrasive propulsion. According to an embodiment, the controller may include or consist of pneumatic logic.

摘要： An abrasive waterjet system in accordance with an embodiment of the present technology includes a cutting head, a catcher downstream from the cutting head, and a conveyance configured to carry slurry including abrasive material and liquid collected from the catcher toward the cutting head. The cutting head includes a jet-forming orifice and a mixing chamber downstream from the jet-forming orifice. The cutting head also includes a slurry inlet through which the mixing chamber receives slurry including abrasive material and liquid collected from the catcher. The abrasive waterjet system can be configured for substantially closed-loop recycling of wet abrasive material. This can be useful, for example, to increase abrasive material utilization efficiency and to decrease abrasive material disposal costs. These and/or other benefits may be realized both in the context of low pressure abrasive waterjet systems and in the context of high pressure abrasive waterjet systems.
