The deposition system includes a laser configured to generate a laser beam. The deposition system is configured to deposit at least one layer on the substrate by injecting a stream of the powder material into the laser beam. The deposition system is configured to shot peen the at least one layer by propelling the shot peen media onto an exterior surface of the at least one layer.

There is disclosed a method for chemically bonding TiNi materials to Nitinol constructs, comprising placing a Nitinol construct within a mold and packing a powder combination comprising Ti powder and Ni powder, and powder comprised of zero or more of the elements Cu, Hf, Zr, Pt, Pd, Au, Cd, Ag, Nb, Ta, O, N, B, and H, into the mold. The method further includes initiating a process of self-propagating high temperature synthesis of the powder combination within the mold to create a chemical bond between the Nitinol construct and a resulting TiNi foam to thereby create a Nitinol and TiNi assembly.

A method for producing a gas turbine component, which comes into frictional contact with a friction partner, includes: providing a base body produced from a superalloy; applying a first metal coating to a surface of the base body facing the at least one friction partner in the mounted state, wherein an additive production method using a first metal powder is used to apply the first metal coating; and applying a second metal coating to the first metal coating, wherein an additive production method using a second metal powder and a pulverulent pore-forming agent is used to apply the second metal coating and, by adding the pore-forming agent, the porosity of the second metal coating is set such that it is greater than the porosity of the first metal coating, and the volume flows of the introduced metal powder and the introduced pulverulent pore-forming agent are set or controlled separately.

A joint prosthesis system is suitable for cementless fixation. The system includes a metal implant component that has a mounting surface for supporting an insert. The metal implant component includes a solid metal portion and a porous metal portion. The porous metal portion has surfaces with different characteristics, such as roughness, to improve bone fixation, ease removal of the implant component in a revision surgery, reduce soft tissue irritation, improve the strength of a sintered bond between the solid and porous metal portions, or reduce or eliminate the possibility of blood traveling through the porous metal portion into the joint space. A method of making the joint prosthesis is also disclosed. The invention may also be applied to discrete porous metal implant components, such as augment.
