2. Gas metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_metal_arc_welding

   Spray transfer GMAW. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).

3. Thermal spraying - Wikipedia

   en.wikipedia.org/wiki/Thermal_spraying

   Wire arc spray is a form of thermal spraying where two consumable metal wires are fed independently into the spray gun. These wires are then charged and an arc is generated between them. The heat from this arc melts the incoming wire, which is then entrained in an air jet from the gun.

4. Plasma transferred wire arc thermal spraying - Wikipedia

   en.wikipedia.org/wiki/Plasma_transferred_wire...

   Plasma transferred wire arc (PTWA) thermal spraying is a thermal spraying process that deposits a coating on the internal surface of a cylindrical surface, or external surface of any geometry. It is predominantly known for its use in coating the cylinder bores of an internal combustion engine , enabling the construction of aluminium engine ...

5. Plasma arc welding - Wikipedia

   en.wikipedia.org/wiki/Plasma_arc_welding

   Plasma arc welding is an arc welding process wherein coalescence is produced by the heat obtained from a constricted arc setup between a tungsten/alloy tungsten electrode and the water-cooled (constricting) nozzle (non-transferred arc) or between a tungsten/alloy tungsten electrode and the job (transferred arc). The process employs two inert ...

6. Cold spraying - Wikipedia

   en.wikipedia.org/wiki/Cold_spraying

   Manufacturing with cold spray technology provides advantages such as the ability to create shapes with no shape or size constraints, more efficient buy-to-fly ratio when compared to machining, and capable of fusing dissimilar metals to create hybrid metal parts – materials such as titanium alloys, copper, zinc, stainless steel, aluminium ...

7. Phosphate conversion coating - Wikipedia

   en.wikipedia.org/wiki/Phosphate_conversion_coating

   Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting.
