PPT-Metallic Foams

Metal foams most are made from aluminium although steel can also be used There are many benefits of metal foams including a very good strengthtoweight ratio Metal foams are cellular structures made with metal rather than polymers . 1 produced as compared to foams where organic, pore foamingparticles are used. Using high-purity aluminum oxide the foamis perfectly suited as high-temperature insulation material upIt is the aim of t Foams Polyurethane foams (PUR foams) are a very versatile material that is used in all areas of modern orthopaedic technology. One distinguishes between rigid cellular material (rigid polyurethane fo Prof. . Priit . Kulu. 2. Outline. High-strength structural steels. High-performance . tool . steels.

ABSTRACT. The accumulation of waste has become a major problem in urban city dumps. There are different kinds of waste that affect our environment, for example metallic and plastic waste. Developing metallic waste collection robot system is mighty challenge. There is very limited research related with robot systems that specialize in the collection and processing of waste. In these slides, we propose robotic system that can be used for waste metallic collection. This robot is equipped with metal detector, ultrasonic sensor, control and power unit, and actuators. This autonomous robot can perform tasks such as obstacle avoidance and metal detection. . lternative . for . Polyurethane . F. oams.  . Overview. Ecomate . P. roduct . R. eview.
