Sintering, also known as powder metallurgy, is a process that consist in apply pressure and a high temperature (ever under melting point) to a powdered material. Thus material compact and form a solid mass. Sintering operation consist basically four phases: Dosage and mixing to get the desired composition of powder. Putting powder into a mould and pressing it to form a green body. Sintering at a high temperature to fuse particles together (usually on a protected atmosphere) Finishing operations. By this method is possible forming material as tungsten, molybdenum, rhenium, or carbon without the need to reach their melting point, that it is very high. Besides sintering presents some more advantages: Completely controlled composition (is possible mix metals and ceramic materials) Doesn't exist loss of material for chips or disrepair. Structural pieces with complex shapes. Controlled Porosity (Impossible by another method). Special properties such as hardness and wear resistance. Great precision and good surface finish. Large series of pieces with narrow tolerances.
