The aim of the final prepared master work is to analyse technologies for painting of agricultural machinery, evaluate their influence on quality of coatings and offer quality improvement suggestions to agricultural machinery manufacturers. Quality of coatings of agricultural machinery is influenced by many factors, therefore resistance of coatings only to the main factors was investigated – water and abrasive particles. The results showed, that the most resistant for the impact of both factors are electrostatically applied coatings, in comparison with conventional and dip coatings. It was determined, that the water absorption by coatings process is described by polynomial equations, while the wear process mostly by power, linear and logarithmic as well. It was observed, that the thermodynamic parameters of the system, properties of coatings, number of layers and thickness, surface preparation method have the most significant influence on the water absorption level. Using the results of the research, one may evaluate and predict the influence of different painting technologies on quality and durability of coatings.
