metal deposition
31Direct metal laser sintering — (DMLS) is an additive metal fabrication technology developed by EOS out of Munich, Germany, sometimes also referred to by the terms selective laser sintering (SLS) or selective laser melting (SLM). The process involves use of a 3D CAD model… …
32Fused deposition modeling — Fused deposition modeling, which is often referred to by its initials FDM, is a type of rapid prototyping or rapid manufacturing (RP) technology commonly used within engineering design. The technology was developed by S. Scott Crump in the late… …
33vapor deposition — A production of a surface film of metal on a heated surface, usually in a vacuum, either by decomposition of the vapor of a compound at the work surface, or by direct reaction between the work surface and the vapor. Also see zinc vapor deposition …
34hard metal facing — a method of increasing the wear resistance of a metal by the deposition of a hard protective coating. Alloys such as Stellite or a metallic carbide are most often used for the coating …
35Ohmic contact — An ohmic contact is a region on a semiconductor device that has been prepared so that the current voltage (I V) curve of the device is linear and symmetric. If the I V characteristic is non linear and asymmetric, the contact is not ohmic, but is… …
36Electroplating — is the process of using electrical current to reduce cations of a desired material from a solution and coat a conductive object with a thin layer of the material, such as a metal. Electroplating is primarily used for depositing a layer of… …

38Fingerprint — This article is about human fingerprints. For other uses, see Fingerprint (disambiguation) …
39Thermal spraying — techniques are coating processes in which melted (or heated) materials are sprayed onto a surface. The feedstock (coating precursor) is heated by electrical (plasma or arc) or chemical means (combustion flame). Thermal spraying can provide thick… …
40Electrowinning — Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution or liquefied. Electrorefining uses a similar process to remove impurities from a metal. Both processes use… …
