摘要:
Gas turbine treatment process includes laser-removing coating (101) from a substrate (103) of a gas turbine component (105) to form laser-induced plasma (107), spectroscopically analyzing the laser-induced plasma (107), and discontinuing the laser-removing in response to the spectroscopic analyzing. Treated gas turbine component (105) includes a laser-affected surface, the laser-affected surface having one or both of modified dimensions and modified microstructure due to being exposed to the laser-removing of the coating (101). The laser-affected surface has a depth corresponding to the laser-removing being discontinued based upon the spectroscopic analyzing of the laser-induced plasma (107) formed from the laser-removing.

An additive manufacturing system, method of manufacturing, and fabricated part. The system uses a material joining laser system to join together foil sheets to form a metal part. The material joining laser system can be configured to join adjacent foil sheets together in a substantially uniform manner. The manufacturing system also includes a material removal system that removes material from selected locations of the foil sheets to shape the foil sheets to correspond with selective slices of the part. The material removal system can be a laser system, such as a laser system configured to remove material from a foil sheet without removing material from an underlying layer. The method implements various aspects of the system to form a part.

An electrode (10) is presented including a sheath (14) formed of a ductile material, an outer coating (16) including a flux material, and a core (12) including at least one of flux material and alloying material. The ductile material may be an extrudable subset of elements of a desired superalloy material and the alloying material may include elements that complement the ductile material to form a desired superalloy material when the electrode is melted. The outer coating may be formed of a flexible bonding material or it may be segmented (18, 20) to facilitate bending the electrode onto a spool. Any hygroscopic material of the electrode may be included in the core to protect it from exposure to atmospheric moisture.

Nanoparticle compositions include a plurality of spherical-shaped nanoparticles and a plurality of coral-shaped metal nanoparticles, each coral-shaped metal nanoparticle having a non-uniform cross section and a globular structure formed by multiple, non-linear strands joined together without right angles. The nanoparticle compositions can be one-part or multi-part compositions. Nanoparticle compositions can have a mass ratio of spherical-shaped to coral-shaped nanoparticles of about 5:1-20:1, about 7.5:1-15:1, about 9:1-11:1, or about 10:1 and/or a number ratio of spherical-shaped to coral-shaped nanoparticles of about 50:1-200:1, about 75:1-150:1, about 90:1-110:1 or about 100:1. The nanoparticle compositions can be used for various purposes, including as an antimicrobial (e.g., anti-viral, anti-bacteria, or anti-fungal composition), fuel additive, or treating fabrics.

Anchoring devices and methods for affixing an implanted lead of a neurostimulation system at a target location in a patient are provided herein. Such anchoring devices includes a helical body having a plurality of tines extending laterally outward from the lead when deployed that engage tissue to inhibit axial movement of the implanted lead. The plurality of tines are biased towards the laterally extended deployed configuration and fold inward towards the lead to a delivery configuration to facilitate delivery of the lead through a sheath. The tines may be angled in a proximal direction or in both proximal and distal directions and may include various features to assist in visualization and delivery of the lead. The anchor may be formed according to various methods, including laser cutting of a tubular section along with heat or reflow to set the material with the anchor in the deployed configuration and injection molding.
摘要:
The invention relates to a method for welding two components (1, 2), in which two mutually adjacent joining surfaces (3, 4) of both components (1, 2) are pressed against each other by applying a force (F), and both components (1, 2) are heated. According to the invention, both components (1, 2) are only welded across part of the height or the width of the components (1, 2) in the region of both joining surfaces (3, 4) on the side facing the heat source (11) by means of a heat source (11).
