In the era of technological progress, where advancements are evolving at a rapid pace, modern approaches to automotive component repair deserve special attention. Through the use of innovative materials and restoration methods, vehicle owners can significantly extend the lifespan of their vehicles. This not only enhances the reliability of automobiles but also reduces the need for frequent repairs, leading to substantial cost savings. Moreover, with the application of modern technologies, the repair by restoration process becomes more efficient, saving both time and resources.
Therefore, analyzing the application of modern gas-thermal coating methods in innovative technologies for the restoration of automotive components, utilizing various gas-thermal spraying techniques during the repair of vehicle parts and assemblies, and ensuring warranty coverage for post-repair service life is highly relevant.
To enhance the efficiency and reliability of restoration processes, modern gas-thermal coating methods in innovative automotive component restoration technologies have been examined, with a focus on their practical application in Ukraine. Additionally, some common coating techniques for the thermal spraying of automotive parts have been analyzed. Their use enables achieving high-performance characteristics of products while minimizing environmental impact.
Wires or powders are used as raw materials. The material may consist of a single element, but more commonly, alloys or composites are employed. These materials are selected to provide the required set of properties, ensuring the functionality of the component or assembly under specified operating conditions and strong adhesion to the base material.
The primary factors, conditions, and parameters of gas-thermal spraying include the composition, dispersity, temperature, and velocity of particles; particle concentration in the gas stream; spraying distance; the composition and properties of the gas medium transporting the particles; the environment in which the coating is applied (composition, pressure, temperature); as well as the material and condition of the substrate surface (roughness, chemical cleanliness).
Thus, innovations in coating application for the restoration of automotive components continue to transform the industry, enabling increased efficiency and durability of technical parts, reducing capital and operational repair costs, and minimizing environmental impact.
