A coating process employing coating techniques which allow an end-user to coat steel, rather than relying on a specialized location or supplier, is provided. The techniques produce a coating having high temperature oxidation resistance, greater corrosion resistance, and added surface lubricity to minimize die wear during a stamping process. The techniques also allow configurability with surface textures and allow thickness control. In addition, selective coating of a part or product, for example, around a weld area, and the addition of componentry, for example sensors, with the sensors being employed to monitor the coating, is possible. The coating includes a top functional layer including least one of Al, Ni, Fe, Si, B, Mg, Zn, Cr, h-BN, and Mo, and an interfacial layer with intermetallics formed therein. The interfacial layer can consist of at least one intermetallic, or the interfacial layer can include a mixture of the intermetallic(s) and steel.

An object is to provide a magneto-sensitive wire that exhibits a stable anisotropic magnetic field even under a high-temperature environment and can achieve expansion of the measurement range of an MI sensor, etc. The present invention provides a magneto-sensitive wire for magnetic sensors that comprises a Co-based alloy having a composite structure in which crystal grains are dispersed in an amorphous phase. The Co-based alloy contains 0.05 to 0.80 at %, preferably 0.10 to 0.60 at %, of Cu with respect to 100 at % of the Co-based alloy as a whole. The Co-based alloy may further contain 65 to 90 at % of the group of magnetic elements consisting of Co, Fe, and Ni as the total, 15 to 27 at % of Si and/or B as the total, and 0.5 to 2.5 at % of Mo. Such a magneto-sensitive wire is excellent in the heat resistance and exhibits a stable anisotropic magnetic field even under a high-temperature environment. By using the magneto-sensitive wire of the present invention, it is possible, for example, to efficiently produce an MI sensor with an expanded measurement range.

Wire products, such as round and flat wire, strands, cables, and tubing, are made from a shape memory material in which inherent defects within the material are isolated from the bulk material phase of the material within one or more stabilized material phases, such that the wire product demonstrates improved fatigue resistance. In one application, a method of mechanical conditioning in accordance with the present disclosure isolates inherent defects in nickel-titanium or NiTi materials in fields of a secondary material phase that are resistant to crack initiation and/or propagation, such as a martensite phase, while the remainder of the surrounding defect-free material remains in a primary or parent material phase, such as an austenite phase, whereby the overall superelastic nature of the material is preserved.

A near net shape medical device is described that is formed from a metal alloy mixture containing NiTiHf using additive manufacturing techniques. The medical device is aged to a desired ultimate tensile strength (UTS), presence of H-phase precipitate with an A.sub.f below body temperature.

An abradable sealing element comprises a substrate and a sealing structure. The sealing structure comprises one or more wall structures extending from the substrate and defining at least one open cell which is filled with abradable material. The one or more wall structures are formed by additive-layer, powder-fed, laser-weld deposition onto the substrate. The one or more wall structures are formed from nickel-based superalloy and constitute from about 10% to about 50% of the total volume of the sealing structure.

A method for altering an orthodontic archwire of a unitary piece of shape memory alloy having a composition and generally uniformly formed properties along its length to different stiffness profiles along the length of the archwire. In one embodiment, the method includes determining a stress profile for teeth at a location. The method may include calculating a force the archwire is to produce on the teeth to satisfy the determined stress profile and determining an altered stiffness of a section of the archwire based on the calculated force. The method may include changing the composition of the section based on the determined altered stiffness. The method may include determining a load for teeth and calculating a force the archwire is to produce on the teeth to satisfy the determined load.
