Metallization is the process of coating the surface of a material with metal to improve its corrosion resistance, aesthetic and mechanical properties. Some of the most common methods of zinc plating are electric arc metallization and gas-thermal spraying. In this article we will discuss the advantages and disadvantages of both methods, as well as their applicability in various industries, with the addition of information about the latest ANTICOR equipment designed for gas-thermal spraying of anti-corrosion coatings.Electric arc metallization
Principle of operation
Electric arc metallization is based on the creation of an electric arc between an electrode and the surface to be coated. This melts the metal, which is then deposited on the prepared surface.
Advantages
1. High speed of application. This method allows large areas to be covered quickly.
2. excellent adhesion. Coatings obtained by electric arc metallization provide good adhesion to the substrate.
3. cost-effectiveness. The low cost of consumables makes this method more affordable.
Disadvantages
1. Difficulty in controlling the process. Will require experience and skills to control the process parameters.
2. Potential formation of oxides. High temperatures can lead to deterioration of coating properties.
Gas thermal spraying
Principle of operation
Gas thermal spraying consists of heating a metal powder in a gas environment and spraying it onto a surface under the influence of compressed air or inert gas. This process produces coatings with specific properties.
Advantages
1. wide choice of materials. Possibility to use various powdered metals and their alloys.
2. Variety of coatings. Resistance to high temperatures and corrosion, possibility to create multilayer coatings.
3. less tendency to oxidization. The process minimizes oxide formation.
Disadvantages
1. Low speed of application. Typically, this method takes longer compared to electric arc metallization.
2. High equipment costs. Specialized equipment is required, which increases initial costs.
ANTICOR equipment: A new approach to metallization
When considering metallization, the new ANTICOR equipment for gas-thermal spraying of anti-corrosion coatings is particularly noteworthy. It combines cost-effectiveness and high application speed, which allows it to compete successfully with electric arc metallization. In addition,
ANTICOR offers all the advantages of gas-thermal spraying.
This modern method works with both pure zinc powder and its mixture with aluminum. This extends the possibilities of application and customization to specific requirements, while ensuring the reliability and durability of the coating.
Comparison of methods
Efficiency
Electric arc metallization is better suited for rapid coating of large surfaces. Gas thermal spraying, on the other hand, can be more effective for specialized, high performance coatings.
ANTICOR equipment, with its high productivity and adaptability, occupies an intermediate position between these two methods.
Cost
In terms of overall cost, electric arc metallization is the more economical option. However, the high equipment costs of gas thermal spraying can be justified by the improved coating quality. The cost effectiveness of
ANTICOR equipment makes this method affordable and profitable.
Application
The choice of method depends on the specific application:
Electric arc metallization - ideal for structures that require a fast, yet reliable rough coating.
Gas-thermal spraying - preferred for highly loaded parts and equipment operating in aggressive environments.
ANTICOR equipment - perfect for those looking for a balance between cost and coating quality.
Conclusion
Both methods have their advantages and disadvantages, and the choice between electric arc metallization and gas-thermal spraying depends on specific tasks and coating requirements. However,
ANTICOR equipment opens up new horizons by combining speed, cost-effectiveness and high quality corrosion protection coatings, which is especially important in today's environment.
