Porous metal coatings using shockwave induced spraying
A new spray process allows for deposition below a critical velocity limit of cold spray, while providing adhesion. Post deposition heat treatment has shown excellent coating strength. A wide variety of materials can be deposited. The spray process is based on ShockWave Induced Spraying (SWIS) but with much slower spray jet projection velocities. High porosity, pore size control, and porosity control are demonstrated to be controllable. Preheating of feedstock and uniform temperature of the SWIS delivery allow for the deposition below critical velocity.

Laser-produced porous surface
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.

Method of manufacturing laminate
A method of manufacturing a laminate includes: forming a preprocessing coating on a surface of a substrate having insulating properties by accelerating the powdered material together with gas and spraying the powdered material in a solid phase onto the surface of the substrate, the powdered material including aluminum or an aluminum alloy as a main component; and forming a heat-treated coating having a surface with irregular asperities by heating a preprocessing laminate including the substrate and the preprocessing coating formed on the surface of the substrate.

Thermal diffuser for a semiconductor wafer holder
An electrostatic chuck is formed by depositing a diffuser layer onto an electrostatic puck and removing areas of the diffuser layer to form discrete diffuser segments separated by gaps. The discrete diffuser segments may define continuous concentric rings, discontinuous concentric rings, or a combination of continuous concentric rings and discontinuous concentric rings. The discrete diffuser segments are separated from each other by forming at least one trench in the diffuser layer. The trench may extend partially through the diffuser layer, completely through the diffuser layer to the electrostatic puck, or have a first portion that extends partially through the diffuser layer and a second portion that extends completely through the diffuser layer. Also, the trench can have a constant width or have a variable width.
