  • From high-performance, economical and environmental points of view, Powder metallurgy process shows remarkable advantages in production of parts and components due to their special compositions by elemental mixing and 3-dimensional near net shape forming methods. Powder metallurgy process can be applied to not only metal materials but also ceramics and organic materials, which both are employed as structural and electrical products.

  • The dual fluidized beds experimental set up is made of transparent perspex material. The system consists of a fast bed riser, a cyclone to separate the solids, a down comer with a L- valve, a bubbling fluidized bed and a return pipe with another L-valve. The system is shown schematically in Fig 1. The solids after passing through the fast bed riser gets separated in the cyclone, descend downwards through the down comer and enter the bubbling bed reactor through the L-valve. A part of bed materials in the bubbling bed system are then transferred back into the...

  • The present volume ofModern Aspects of Electrochemistrybrings readers the newest developments and achievements in the product ion of metallic powders by electrochemical and electroless methods from aqueous solutions. Although the deposition of metallic powders from aqueous solutions was intensively studied for years, the last summarized results (Calusaru) on this topic were published in 1979. Electrochemically and chemically produced metal powders from aqueous solutions are of high purity.

  • POWDER METALLURGY has been called a lost art. Unlike clay and other ceramic materials, the art of molding and firing practical or decorative metallic objects was only occasionally applied during the early stages of recorded history. Sintering of metals was entirely forgotten during the succeeding centuries, only to be revived in Europe at the end of the 18th century, when various methods of platinum powder production were recorded (

  • Magnesium is the lightest of all the metals and the sixth most abundant on Earth. Magnesium is ductile and the most machinable of all the metals. Magnesium alloy developments have traditionally been driven by requirements for lightweight materials to operate under increasingly demanding conditions (magnesium alloy castings, wrought products, powder metallurgy components, office equipment, nuclear applications, flares, sacrificial anodes for the protection of other metals, flash photography and tools). The biggest potential market for magnesium alloys is in the automotive industry. ...
