What is friction processing?

friction processing is a technique of metallurgy that combines metals through increased friction without melting. The friction processing method begins with the tool with a piece of metal. Then the tool moves quickly around the metal and increases heat and friction until the separate pieces of metal in the machine are connected. This usually does not cause any phase change that is usually needed to combine metals. Along with the use of less energy, it also improves microhardiness metal and its tensile strength and fatigue.

To start the friction processing, several pieces of metal are placed in the mixing processor. The main piece of metal, the one that connects other metals, pierces it. This rod is a metal, but does not absorb during processing because it only has to increase friction and help in processing. The movements become more intense with the progress of the papers, causing friction to accumulate between all different pieces of metal. When enough friction is produced through friction processing, all metals are joined into one.

While there are many ways to combine pieces of metal, friction processing differs from the majority, because there is no change in phase during the connected process. The metal must usually be melted or rotated from the solid to the liquid. With the friction process, intensive friction has enough force to cause metals to connect even if they remain solid during the process.

There are many advantages when using friction processing. One of these advantages is to maintain energy. When the metal has to melt, it requires a huge amount of heat, which requires a lot of energy and many specialized tools made to hold an incredibly hot molten metal. This is expensive and can be very dangerous if one of the molten metal escapes and workers are exposed to him.

Another benefit for this process is that the metal itself often improves much more than it would be through other metallurgical operations. For example, microHardness, pEvidence of fatigue and tensile strength usually doubles or three times, depending on the used and connecting metals. The use of high heat can also soften the metal after processing, which may be a problem if it is needed for construction, laboratory tests or any other purpose.
