Cu surface modification in atmospheric plasma surface treatment system inhibits micro-discharge

Cu surface modification in atmospheric plasma surface treatment system inhibits micro-discharge

Cu surface modification to suppress microdischarge in atmospheric plasma surface treatment system: In power transmission lines, conductors may be damaged during line construction (such as on-site production of cable joints, erection of high-voltage overhead lines, etc.), which is easy to cause serious distortion of local electric field. Under the action of strong field, the air around the conductor will be ionized, and even the electrons in the metal body will be pulled out, thus leading to local micro-discharge. Atmospheric plasma surface treatment system Long-term partial microdischarge is one of the important factors causing insulation failure of transmission lines, which seriously affects the safe and stable operation of transmission lines. Therefore, finding an effective method to suppress the microdischarge caused by microdefects on the surface of conductors has become a research hotspot. The plasma of atmospheric plasma surface treatment system has the advantages of high concentration of highly active particles and low excitation temperature, which has been widely used in many fields. With the rise and development of the subject of material surface modification, the method of using plasma surface modification has been widely concerned. Plasma surface modification uses the energetic active particles in the plasma to bombard the surface of the material and endue the surface with new properties. Since it only acts on the surface, the original bulk properties of the material remain unchanged. It should be pointed out that plasma has no requirement on the substrate material, so it can be used for surface modification of metal materials as well as insulating materials. Atmospheric plasma surface treatment system technology is used to modify insulating materials, fluorine treatment and SiO film deposition, which can effectively regulate the modified groups and improve the insulating properties of materials. After the surface modification of epoxy resin by atmospheric plasma, the surface roughness of the material increases, and the introduction of fluorine-containing groups increases the voltage of the epoxy in vacuum. Plasma jet driven by RF power supply deposited silicon oxide thin films on silicon wafer, using HMDSO and O2 as reaction precursors, the thin films were obtained under favorable treatment conditions by optimizing O2 flow rate and RF power supply. The surface of copper and copper was treated by air dispersion discharge. It was found that the surface hydrophilicity and surface energy of copper and copper were effectively improved by plasma treatment in the atmospheric plasma surface treatment system. Li Wenyao et al. used the method of atmospheric pressure plasma enhanced chemical vapor deposition to deposit SiO2-like insulating film on copper and copper, and made use of the good dielectric properties and high resistivity of the silicon oxide film itself to suppress the occurrence of corona. The work function of metals is the main factor affecting the field emission threshold electric field. With a slight change in the work function, titanium tetrachloride (TiC4) is a common precursor for the preparation of TiO2. TiO2 can be generated through hydrolysis, and the reaction is easy to proceed at room temperature without producing organic waste. Using titanium tetrachlide (TiCl4) as a titanium source, low temperature plasma jet was used to deposit TiO2 films on the surface of copper and copper to change the surface characteristics of the conductor and block the microdefects, so as to inhibit the occurrence of microdischarge. After plasma treatment, the surface work function of Cu wafers is increased from 4.65eV to 4.87eV, the electric field distortion is improved, and the field intensity is reduced from 1.4x106 V/m to 9.89x105V/m. The plasma treatment method can improve the electric field distortion to a certain extent and inhibit the occurrence of local microdischarge.

They are used to solve problems related to adhesion and wetting in many industries.         1. Introduction to plasma         Plasma is a state of existence of matter, usually in three states: solid, liquid, and gas, but in some special cases, it may also exist in the fourth state, such as substances from the surface of the sun and the ionosphere of the earth’s atmosphere. . This state of matter is called the plasma state, which is the fourth state of matter. The following substances exist in the plasma, and electrons are in high-speed motion; neutral atoms, molecules, and atomic groups (radicals) are in an activated state; ionized atoms and molecules; ultraviolet rays generated in the decomposition reaction of molecules; unreacted molecules and atoms And so on, but the substance is still neutral as a whole.         2. How to generate plasma         Various forms such as arc discharge, glow discharge, laser, flame or shock wave can transform gaseous matter under low pressure state into plasma state. For example, gas molecules, such as oxygen, nitrogen, methane, and water vapor, in a high-frequency electric field at low pressure, when the glow discharges, they will decompose accelerating atoms and molecules, so that the generated particles will be decomposed. Dissociate into electrons and positively and negatively charged atoms and molecules. The charged particles and electrons produced in this process gain high energy when they are accelerated in the electric field, and collide with surrounding molecules or atoms, so that the molecules and atoms are re-excited by the electrons, and they themselves are in an excited state. And ionic state, when the matter is in a plasma state.         3. Types of plasma in vacuum plasma surface treatment system         According to the temperature, it can be divided into two types: high temperature plasma and low temperature plasma.         According to the different chemical properties of the gas used when generating the plasma, from the perspective of the activity degree of the gas, the plasma can be divided into reactive gas plasma and inert gas plasma.         4. The effect of plasma on the surface of an object         In addition to gas molecules, ions and electrons, there are also atoms or groups of atoms (also called free radicals) that are excited by energy in the plasma of the vacuum plasma surface treatment system, as well as the light emitted by the plasma. Among them, the wave of The length and energy level play an important role when the plasma interacts with the surface of the object.         1) Free radicals such as radicals react with the surface of the object.         2) The effect of electrons on the surface of an object.         3) The effect of ions on the surface of an object.
