• Mechnical Vacuum Pump Selection Considerations for Ion Pressure Nitriding, Plasma Nitriding and Nitro Carborising (.pdf)
  of nitriding obtained, and hence the resulting. surface properties of the work-piece, is controlled by adjusting various process parameters which. govern the rate and depth of nitrogen diffusion into the metal surface. Nitriding was historically developed using very high temperature molten salt baths...
• Carpenter Technology outlines how high-tech melting creates high-performance metal alloys
  is high-strength alloys that also possess good fatigue resistance, toughness, and ductility. Melting metal alloys is a common way to purify them. Impurities like oxides can be skimmed off molten metal while controlled solidification dictates the cooled alloy’s phase and grain structures. As the name...
• Thermal spray: Better performance for less
  or ceramic powders are injected. The electric spray gun propels the molten material onto the substrate at a high velocity. As the coating cools it mechanically bonds to the substrate. In addition to metal deposition, plasma spray also is used to deposit thermalbarrier coatings (TBCs), which resist heat...

• Advanced ceramics
  expansion is a necessary property for resistance to thermal fracture. Glass ceramics: Glass ceramics are formed from molten glass and subsequently crystallized by heat treatment. They are composed of several oxides that form complex, multiphase microstructures. Glass ceramics do not have...
• New from the Fab Labs: Lightweight but Superstrong Parts
  is quite important. "The direction has to do with how uniformly the heat is distributed," says Cormier. "Think of EBM in terms of a wave. When the beam scans from left to right, say, it generates a little wave of molten titanium. Always scanning in that one direction might produce a little lip...
• The Secret is in the Lining: The Use of Fluoropolymer Materials For Corrosive Pumping
  of the fluoropolymers. Its melting point is 627 F with a maximum service temperature of 500 F. PTFE is virtually inert to chemical attack with the exception of a few very highly reactive chemicals, which include molten alkali metals, fluorides of chlorine or oxygen and free fluorine. ETFE...

  . and alloy, vaporizing portions of the flux, liquefying the. hotter, it gets thinner and spreads more readily. This. alloy, and conducting heat through the molten metal to the. causes it to preferentially flow towards points of heat. surfaces to be soldered. This technique works well on. The closer...
• Vacuum Requirements for Steel Degassing (.pdf)
  by improving their quality and supplying more special steels. For reasons of economy these processes are usually conducted on large quantities of. molten steel in very large plants, and consequently very large vacuum pumping. capacities are usually required. These processes are potentially very...

  with a unique perfluorinated cure site monomer added. They possess excellent chemical resistance and the highest thermal stability of any elastomer available today. Both attributes are essential for sealing aggressive semiconductor environments. The only limitations are an inability to seal molten...
