A method for repairing an at least externally coated hollow component. The direct mechanical machining of a coated component after use removes the need for a coating-removal and selective hollowing step and a selective repair of cracks, since a design adaptation leads to a component being engineered or used such that it can be used again as a result of external dimensional stipulations.

The present disclosure provides a magnetostrictive guided wave sensor and a method for preparing magnetostrictive coating, relating to the field of magnetic functional materials and preparations thereof. The method includes: pretreating a surface of a test piece; and spraying magnetostrictive alloy powder on the pretreated surface of the test piece to form a magnetostrictive coating attached to the pretreated surface. In the magnetostrictive guided wave sensor and the method for preparing magnetostrictive coating according to the embodiments of the present disclosure, by spraying the magnetostrictive coating on the test piece, no coupling agent is required between the probe of the magnetostrictive coating sensor and the test piece, and the magnetostrictive coating can be formed on test pieces of any shape. In addition, the coating has a high bonding strength with the test piece, and has good tissue characteristics and magnetostrictive performance.

Methods of forming a desired geometry at a location on a superalloy part are disclosed. The method may include directing particles of a powder mixture including a low melt temperature superalloy powder and a high melt temperature superalloy powder to the location on the superalloy part at a velocity sufficient to cause the superalloy powders to deform and to form a mechanical bond but not metallurgical bond to the superalloy part. The directing of particles continues until the desired geometry is formed. Heat is applied to the powder mixture on the repair location. The heat causes the low melt temperature superalloy powder to melt, creating the metallurgical bonding at the location. Another method uses the same directing to form a preform for repairing the location on the part. The low melt temperature superalloy powder melts at <1287° C.), and the high melt temperature superalloy powder melts at >1287° C.

Apparatus and methods for making metal-connected particle articles. A metal containing fluid is selectively applied to a layer of particles. The metal in the fluid is used to form metal connections between particles. The metal connections are formed at temperatures below the sintering temperature of the particles in the layer of particles.

A device, and method, for laser cladding, in particular for extreme-high-speed-laser cladding (EHLA), comprising: at least three drive columns; a workpiece support for a product to be manufactured, the support being positioned centrally between the drive columns, and/or a support plate for a welding head, which is movably connected to the drive columns in three spatial directions (x, y, z) via multiple tension-compression struts and revolute joints that are fixed on the ends thereof, wherein, each drive column has at least one inner guide rail facing the workpiece support and/or the support plate with an inner carriage running in said rail for moving the workpiece support and/or the support plate in the three spatial directions and has an outer guide rail with an outer carriage running therein for guiding a counterweight vertically in the opposite direction to the inner carriage; and a welding head.

Provided are a method and a system for controlling the overlapping in the single-layer laser cladding of a shaft-like workpiece, and a method, a device and a system for dynamically adjusting a height of the laser head of a laser cladding machine. In the method for controlling the overlapping in the laser cladding of the shaft-like workpiece, the motions of the spindle and the feed shaft are planned based on an S-curve acceleration and deceleration method. The motion planning is dynamically adjusted by comprehensively considering the overlapping rate and the clamping allowance of the workpiece in a feed direction.

This invention relates to a method, system and apparatus for cladding a surface of an articles subject to corrosive, erosive or abrasive wear, such as impact or grinding tools. The method includes providing a supply of stock material and feeding the stock material towards a portion of the surface of the article via a dedicated feed source. A dedicated heat source heats the fed stock material and the portion of the surface of the article such that the heated stock material and the portion of the surface at least partially melt. Upon removal of the heat, the molten feedstock and the surface portion form a bonded coating layer on at least a portion of the surface of the article, thereby protecting that part of the assembly against wear.

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.
