What is the difference between plasma spraying coating equipment and ultrasonic spraying machine! Which one is better.

Ultrasonic spray coating machine and plasma spray coating machine are two different surface treatment technology equipment, with significant differences in working principles, application characteristics, and advantages. Here is a detailed comparison between the two:

1、 The working principle is different:

Ultrasonic spray coating machine: converts high-frequency sound waves into mechanical energy through a piezoelectric transducer, and then converts the mechanical energy into liquid to atomize the liquid into fine particles, which are then uniformly coated on the surface of the substrate through a carrier gas to form a coating or film.

Plasma spray coating machine: The process of using high-energy ion beams to assist in the formation of coatings by depositing deposits. Plasma is generated by introducing inert gases (such as argon), and then using electric field force to convert substances (such as metals, ceramics, etc.) into ionic states and deposit them on the surface to be treated, forming a uniform coating.

Working principle: Using a plasma source to generate an ion beam, by controlling the energy and flow rate of the ion beam, it interacts with the substrate to be coated, generating a series of physical and chemical reactions to deposit the coating material on the substrate.

2、 Application features and advantages

Ultrasonic spray coating machine: suitable for high uniformity sub micron and nano film coatings. Widely used in industries such as fuel cells, solar cells, glass coatings, electronic circuits, etc. Ultrasonic spraying equipment can coat grooves with a high aspect ratio with high uniformity, and has the advantage of unobstructed atomization spraying.

Advantages: It greatly improves the encapsulation and uniformity of the microstructure, making the coating of the equipment more stable on the microstructure and reducing the performance differences caused by uneven coating.

AF9000-800 linear plasma fully automatic coating machine: It can be used to prepare excellent coatings with high hardness, wear resistance, and corrosion resistance. It can accurately control the performance and thickness of coatings and meet the requirements of coating characteristics in different application fields. Suitable for various substrates and coating materials, such as metals, ceramics, and plastics.

Advantages: It has a high sedimentation rate, can quickly form a uniform and dense coating, and improve production efficiency. The formed coating can cover the microstructure of the substrate surface, effectively improving the adhesion and corrosion resistance of the coating. Environmentally friendly, no need to use harmful solvents and chemicals during the coating process.

3、 Applicability of Coating Materials

Ultrasonic spray coating machine: more suitable for liquid coating materials, especially for materials that are temperature sensitive and cannot withstand high temperature treatment, such as solutions containing bioactive ingredients, polymer solutions, etc. These materials can be well atomized under the action of ultrasound and deposited into thin films at relatively low temperatures without losing activity or decomposing due to high temperatures. For example, in the preparation process of biosensors, an ultrasonic spray coating machine is used to spray a solution containing biological enzymes onto the surface of the sensor, forming a biosensing film.

AF9000-800 linear plasma fully automatic coating machine: capable of processing various forms of coating materials, including powder and liquid materials. The plasma spray coating machine has advantages for high melting point and high hardness materials such as metal ceramics and refractory metals. Because the high temperature of plasma can melt these materials and evenly spray them onto the substrate. For example, when preparing wear-resistant coatings on metal surfaces, a plasma spraying coating machine can be used to spray tungsten carbide powder onto the metal surface, forming a good wear-resistant coating.

4、 In terms of film quality

Ultrasonic spray coating machine: Due to the deposition of atomized droplets, the film formed is relatively uniform and flat. The atomization effect of ultrasound can generate droplets with relatively uniform particle size, and the deposition of these droplets on the substrate can form a smooth thin film surface. However, due to the fact that droplets mainly rely on solvent evaporation and natural fusion between droplets during the deposition process, the density of the film may be relatively poor. For example, in the preparation process of anti reflective films for optical lenses, ultrasonic spray coating machines can produce thin films with lower surface roughness, which is beneficial for reducing light reflection.

The thin film formed by the AF9000-800 linear plasma automatic coating machine usually has high density and good adhesion. Due to the high-speed impact of coating materials on the substrate surface and rapid solidification to form a thin film, the bonding between material particles is tight. Meanwhile, plasma has a certain cleaning and activating effect on the substrate surface, which can enhance the adhesion between the film and the substrate. However, due to the high-speed impact of the material during the spraying process, it may cause a certain degree of roughness on the surface of the film. For some application scenarios that require high surface flatness, further surface treatment may be necessary.

In summary, the above is an explanation of the working principles, characteristics, advantages, applicability, and other aspects of plasma spray coating machines and ultrasonic spray coating machines.
