Material surface treatment in many ways, but its essence is substantially the same, all by changing the organizational structure of the surface material

Surface modification of metallic materials There are many ways , more traditional methods such as carburizing, carbonitriding , ion precipitation penetration, thermal spray technology , electroless plating technology, laser surface modification technology, although the material surface treatment in many ways, but is substantially the same, are the surface by changing the material structure in order to achieve the requirements . Briefly , chemical treatment processes are basically the chemical reaction medium , the diffusion boundary layer , surface adsorption and diffusion  Abrasive grinding  reaction and the process of four separate sub- component , but four processes associated with each other , each constraints are indispensable. Although these techniques mentioned above have many advantages, already in production and daily life have been widely used , and has achieved great results , but there are also  synthetic diamond  or penetration effect confined near the surface and other issues , the effect can not reach certain technical  Diamond blade . Such as the use of thermal spray technology to change the surface properties of materials , although the technology has a variety of base material for spraying , the cost is relatively low , significant economic benefits , etc., but there are also coated impact resistance and corrosion resistance is not high, the spraying process on the environment and harmful to the operator and other shortcomings . Another example carburizing treatment , although simple process, but relatively shallow depth of penetration , and thus in the actual production has significant limitations.
