ENGINE BLOCK MATERIALS AND ITS PRODUCTION …
The graphite in the cast iron block surface works as a lubricant during machining as well as during the engine operation. The lubrication offered by graphite on the wall surface reduces the frictional force between the wall and the contacting surfaces. Some solid lubricants known are Sn, Pb, Graphite, MoS 2 (Molybdenum disulfide), WS

Graphite Processing Plant
A basic process is thermal treatment in the presence of caustic reagents to dissolve siliceous impurities such as quartz, feldspar or mica. The graphite concentrate is mixed with caustic reagent and calcined at elevated temperatures. After calcination the graphite is leached with water washing away dissolved impurities.

Graphite production further processing
The final step in graphite manufacture is a conversion of baked carbon to graphite, called graphitising, i.e. heat-treating the material at temperatures in the region of 2600°C – 3300°C. During the graphitising process, the more or less pre-ordered carbon (turbostratic carbon) is converted into a three-dimensionally ordered graphite structure.

The most common and widely used method for manufacturing engine blocks is sand casting. In the case of aluminium, sometimes die casting is also used. The sand casting uses sand moulds made from a combination of sand and binders to maintain the mould cavities. Sand moulds are cheaper to produce and can only be used once per casting.

Artificial Graphite
Artificial graphite (nongraphitic carbon) is fabricated by heat treatment of petroleum coke, coal-tar pitch, or oil. Specific capacity and reversibility is lost at high temperatures from 1000 Ah kg −1 (at 500 °C) to 150 Ah kg −1 (1800 °C). Above 2000 °C, an increasing degree of graphitization improves capacity again (200–300 Ah kg −1) and minimizes irreversible …
