Recommend the materials for the following items. Pumps surgical tools Pressure vessels Aircraft Structures Concrete

Solution

1. In general the material for the pumps should have corrosion resistant, load bearing capacity, light weight, castability, machinability, good thermal conductivity, reasonable property. Best on requirement we can design pumps with materials like Aluminium, Cast iron, Brass, Bronze, Plastic, Stainless steel.

2. Surgical tools materials should have corrosion resistant, not having cytotoxic property, sufficient hardness to avoid wear, low weight, good heat treatment property, castability, machinability. The materials like Stainless steel, Titanium, Tungston carbide used for making surgical tools.

3. Pressure vessels has to withstand heat, pressure, thermal cycling loading, tension and compression loading, corrosion and errosion. The matrials should have high tensile and compressive strenght, excellent thermal characteristics, hight fatigue strength, abrassive resistant, corrosion and errosion resistant. For the manufacturing point of view, it should have good ductility, weldability, formability. Wroght iron, Steels can be used for manufacturing of pressure vessel.

4. The most important reqirement of material for Aircraft structure is low weight and formability, corrosion resistant and having execellent fatigue property. Aluminium alloy, titanium alloy, fibre glass, carbon fibre are extencively used as aircraft material.

5. Concrete should have high compressive strength, bond strength, abrassive resistant and should withstand cycling thermal loading. Cement, crushed stone, sand, flash ass, silica fume is used as cocrete making material.
