Molten-lnth spraying
A spraying method in which the spraying material is heated to a decomposed state by a hot chemical gas (compressed air or its mixture) and then sprayed on a pre-treated substrate surface. In most cases, the spraying material has been heated in a device. 1.4.3.2
Flame spraying kpraying
The spray material is heated in oxygen-fuel gas and then reaches the state of chemical reaction after being pre-treated. The initial spray material can be in the form of powder, jet, flexible wire or wire. It can only use oxygen-fuel jet, or it can also use other gas (such as compressed air) to heat the material to the substrate. 4. 3. 2. 1
Wire flame sprayingWire flame spraying is a process of continuously sending the energy of the shallow particles to the chemical state by using oxygen-fuel flame to move them to the chemical state, and then spraying the pre-treated benzene by using the gas (for example, compressed air) spraying. See Figure. The fuels used are acetylene, hydrogen, liquefied petroleum gas, etc. Wire flame spraying includes, flame spraying, flexible flame coating and other gas technology:

Entertainment explosion spraying will not be certain In the combustion chamber of the spray gun, the gas mixture of the fuel gas will explode and burn in a controlled manner for a certain period of time. The high-speed hot air flow will heat the powder to the desired state or melt state, and then the powder will be directly sprayed onto the pre-treated surface to form a coating. The method of spraying the powder by the spray gun is to use the magnetic explosion exchange group, and the gas injected by the spray gun is used to generate shock waves to heat the powder particles in the spray gun, and then directly spray them onto the pre-treated surface. After each spraying, the chamber and the spray gun are sprayed with gas, as shown in Figure 6. 4.3. 5
Electromagnetic spraying

Electromagnetic spraying is to use the two metals to produce electric charge between the tops of the two metals, the two metals can be of the same composition, and the gas flow can be different! A process for forming a coating by atomizing the compressed air and applying the atomized material to the treated surface. 4.3.6 Plasma spraying plasmaspraying 4.3-6.1 Atmospheric plasma spraying Atmospheric plasma spraying is referred to as plasma spraying. It is a process for heating a material to a molten state by using a jet of air and spraying it onto a pre-prepared surface. CB/T18719-2032: In the jet, an electrode (the one pressed by the jet) is used to heat the material to a molten state and spray it onto the pre-prepared surface. ) spray end Yang garbage!

Medical. Plasma spraying is a solid solution. The air pressure in the sealed room can be low. When the air pressure in the sealed room is opened, the plasma spraying can be carried out. By controlling the flash gas in the room or the hood, the indoor jet tube can reduce the gas droplets. At the same time, the substrate and the cleaning agent are provided with a cooling loop.

Liquid plasma spraying is stahilied Plasnaapraying is generally used as a plasma forming medium. For example, water, ethanol or alcohol, etc., is busy between the ink cathode and the rotating water-cooled garbage to generate an arc; the liquid reaches the room with a vortex, and the ion flow is continuously formed in the air chamber, which is formed at a stable rate. The ion flow is generated in the air chamber and the air is heated. The ion flow is generated by the air in the air chamber, and the air is heated. The air in the air chamber generates a layer of plasma. The air is sprayed with the liquid. The liquid is used as a plasma forming medium. For example, water, ethanol or alcohol, etc., is used to generate an arc between the ink cathode and the rotating water-cooled garbage; the liquid reaches the room with a vortex, and the ion flow is continuously formed in the air chamber, which is formed at a stable rate.
