Marine steam engine which is more used in ship for creating power for supply to mechanical energy in a ship. Reciprocating steam engine is more used in ship.  After world war II people made steam engine which create a large amount of power. But day by day change of technology now more used in ship diesel engines and steam turbines. In 1712 Thomas Newcomen first commercially developed Marine Steam Engine who was a Scottish engineer. After one hundred year in 18 th century steam engine more developed and walk on way of water which is 1 st steamboat ride in world successfully. Following this 1807 Robert Fulton successfully developed a watt engine. In 19 th century Marine steam engine is more developed by scientist. And Marine Steam Engine divided by two method of manufacture number one is Cylinder technology and number two is connection mechanism. Some example of connection mechanism is crosshead, side lever, vibrating lever, vertical, oscillating, back acting, trunk...

FCC means Face-Centeres Cubic structured which is known to all as a crystal structure.  Carbon variation and arrangement of a metal and which is fully stable allotrope. In whole world diamond is highest precious metal and it contains high corrosion resistance, hardness and also contain high thermal conductivity. Diamond stability is not grater than graphite but it is more use   diamond in our practical purpose. Diamond Application sector in industry, as a cutting tool, hard rigid, knives, cell and so on. Why diamond is various color? In a atom all carbon atoms make a strong covalent bong which greater than any other bond. All diamond contain some another metals which is very small amount but not negligible. It is used in various purposes. Diamond color is blue when it contain boron, Diamond color is green when it is comes to sun light. Diamond color is yellow when it   contain nitrogen metals. Diamond color is brown when it contains some residue whi...

Powder metallurgy techniques are used for the production of refractory metals, composite metals and porous metals and metal nonmetlas combinations and more efficient production method for certain parts.The high melting points of refractory metals make it impossible to use the conventional melting and casting techniques. The use of powder method for the manufacture of tungsten filament was described at the beginning of this chapter. This techniques only for the practical method of producing molybdenum, tantalum and others metals of the same group.  One of the outstanding uses of powder metallurgy is the combination of hard metals in th metallic matrix, which serves as the basis for cemented carbide products. In the production of cemented carbides in cutting tools, a suitable mixtures of the carbides of tungsten, tantalum and titanium with cobalt as a binder is compacted and presintered. In this condition metal can be cut, machined and ground to the final shape. The compact i...

                                                     When work piece attach with locating and it no move up and down or any where or small distance where it set up. This pressure is called clamping. The mechanism of clamping is called clamp. Tool is used it is called clamp and this pressure is called clamping. People find various types of clamps such as Hydraulic and pneumatic clamp, Latch, Toggle, Cam, Wedge or key, Strap, Rock and pinion and Screw. There have some requirement for clamping which is must be needed.   Rigidly held work piece in a position. Duration time should be minimum as soon   as possible when it is load or it has no load. Clamping should be work as a high speed that’s means quick mechanism. When force applied in the work piece clamping should be given a positive feedback. And also think and be careful   work ...
