Cobalt Chrome Alloy is composed of two or more than two kinds of metal and metal or nonmetallic by a certain method of synthesis of metal properties of the material. Generally obtained by melting into a uniform liquid and solidified derived. According to the number of components, can be divided into binary alloys, ternary alloys and multi-alloy. The first human-made alloy from the production of bronze, the world's first production of the ancient Babylonian people, the ancient Babylonian people began to extract 6000 years ago, bronze (copper and tin alloy). China is also one of the earliest countries in the world to study and manufacture alloys. In the Shang Dynasty (more than 3,000 years ago), the technology of bronze (copper-tin alloy) was well developed. By the sixth century BC (late Spring and Autumn) Overheating) a sharp sword.
Alloy is a macroscopically uniform, multi-chemical substance containing metal elements, generally with metallic characteristics. Any element can be used as alloying elements, but a large number of added metal is still the most basic, independent material composition of the alloy called component or Referred to as the yuan. By the two components of the alloy is called binary alloy, composed of three components of the alloy called ternary alloy, composed of more than three components of the alloy called multi-alloy. Solid, alloy May be a single phase may also be complex phase mixture; may be crystalline, may also appear quasicrystalline or amorphous state of the crystalline alloy according to the atomic radius of its constituent elements, negative and electron concentration and so the difference is different , It is possible that the solid phase having the same structure as the pure element of the substrate and the intermediate phase not having the same structure as any of the constituent elements may appear. The mesophase includes normal valence compounds, electron compounds, laves phase, sigma phase, interstitial phase and interstitial compounds of complex structure, etc. Phases that may appear in the equilibrium state of the alloy can be seen from the phase equilibrium diagram.
The structure and properties of the phase in the alloy play a decisive role in the performance of the alloy, while changes in the alloy structure, ie, the relative amount of phase in the alloy, the change in grain size, shape and distribution of the phases, also affect the properties of the alloy Therefore, the use of various elements combined to form a variety of alloy phase, and then through the appropriate treatment may meet a variety of different performance requirements. Polymer chemistry is also borrowed from the term alloy, which refers to under certain conditions, the polymer or copolymer with another polymer or elastomer blend of composite materials, such as styrene - acrylonitrile copolymer resin Blend with butadiene-acrylonitrile rubber.
