• Magnesium takes on aluminum and steel
  U.K.-based Keronite PLC and Thixomat Inc., Ann Arbor, Mich., have joined forces to produce electrolytic-treated Thixomolded magnesium alloy parts. Keronite surface treatment quickly converts the surface of light alloys into a dense, hard ceramic oxide. The 5 to 50- m-thick layers have porous...
• Corrosion Resistant Alloys, Metals & Steel
  . The best corrosion resistant steels in the world find their way into countless applications, from defense to aerospace, turbines and more. Acidic degradation can be easily staved off by the addition of chromium, which not only strengthens the alloy, but creates a passive oxide layer that essentially seals...
• Liquid Silicone Material and Properties
  applications. The most general. formulations provide direct strong bonds onto most thermoplastic surfaces and. metals including aluminum, magnesium and steel. When overmolding to. thermoplastics, due to the high curing temperatures, glass-filled temperature. resistant thermoplastics such as Polymides, PBTs...
• Metal-Matrix Composites
  the matrix properties of superalloys, titanium, copper, magnesium, or iron. Like all composites, aluminum-matrix composites are not a single material but a family of materials whose stiffness, strength, density, and thermal and electrical properties can be tailored. The matrix alloy, the reinforcement...
• New Way To Make Dense Complex-Shaped Ceramics At Lower Cost
  that are 40 percent lighter than plain tungsten.". In another test, the engineers formed a composite of magnesium oxide and plain magnesium at 900 C (1,650 F). Other reactions have taken place at temperatures as low as 750 C (1,382 F), Sandhage said. One obvious application involves rocket nozzles...
• Brazing Processes
  and the filler metals being used. Base metals with readily reducible oxides can be brazed in an atmosphere of combusted natural gas or cracked ammonia. Dry hydrogen, a powerful reducing agent, can be used for brazing most stainless steels and many nickel, cobalt, and iron-base alloys. Heat-resistant...
• Advanced ceramics
  crucibles and furnace bricks. Transformation-toughened zirconia ceramics are among the strongest and toughest ceramics made. These materials are of three main types: Mg-PSZ (zirconia partially stabilized with magnesium oxide, Y-TZP (Yttria stabilized tetragonal zirconia polycrystals), and ZTA...
• Preventing Corrosion in Cooling Systems
  among the most common and damaging forms of corrosion in stainless steel alloys, but it can be prevented by ensuring that the material is exposed to oxygen and protected from chloride wherever possible. Stainless steels high in chromium, and particularly molybdenum and nitrogen, are more resistant...
