Comparision of MMCs techniques .
|Diffusion bonding||High||Used to make sheets, blades, vane shafts, structural components||Handles foils or sheets of matrix and filaments of reinforcing elements|
|Powder metallurgy||Medium||Mainly used to produce small objects (especially round), bolts, valves, high-strength and heat resistant materials||Both matrix and reinforcements used in powder form, best for particulate reinforcement. Since no melting is involved, no reaction zone is develops, showing high-strength composite|
|Liquid-metal infiltration||Low/medium||Used to produce structural shapes such as rods, tubes, beams with maximum properties in a uniaxial direction||Filaments of reinforcement used|
|Squeeze casting||Medium||Widely used in automotive industry for producing different components such as pistons, connecting rods, rocker arms, cylinder heads, suitable for making complex objects||Generally applicable to any type of reinforcement and may be used for large scale manufacturing|
|Spray casting||Medium||Used to produce friction materials, electrical brushes and contacts, cutting and grinding tools||Particulate reinforcement used: full density materials can be produced|
|Compocasting/rheocasting||Low||Widely used in automotive, aerospace, industrial equipment and sporting goods industries, used to manufacture bearing materials||Particulate reinforcement used: full density materials can be produced. Suitable for discontinuous fibers especially particulate reinforcement|
