This scientific work is aimed at researching the testing methods of paint coatings used for protecting the metal parts of automobiles in order to determine their resistance to corrosion processes. Paint coatings are used to protect the metal surfaces of automobiles from corrosion in various climatic conditions and under the influence of aggressive factors such as atmospheric conditions, chemical substances on the road, polluted air, and other corrosive environments, making their quality and effectiveness of great significance.
Different methods of testing paint and varnish coatings are considered, such as neutral salt spray test, acetic acid salt spray test (with and without copper acceleration), and cyclic corrosion testing. Attention is also given to parameters such as test duration, temperature regimes, and chemical aggressiveness of the environment to establish the effectiveness of these methods. The analysis of the tests allows determining which methods best meet the requirements for assessing the corrosion resistance of paint coatings. The work also investigates the impact of various factors, such as the type of paint coating, surface preparation, and operating conditions, on the test results. It was determined that the proper selection of test methods and adequate assessment of their effectiveness help in improving the corrosion resistance of the paint coating in various operating conditions.
The work has important practical applications in the automotive industry by enhancing the quality of protection for automotive coatings against corrosion and extending their service life in various operating conditions. The obtained results will help improve the quality and durability of paint coatings, metal structures, and other products against corrosion by choosing the optimal method for testing paint coatings. This scientific work has practical significance for engineers and manufacturers involved in the development and application of corrosion-resistant coatings.
