Comparison of the tribological properties of flat steel products with heterogeneous organic coatings

Purpose: Comparison of tribological properties of coated metal sheets. Design/methodology/approach: Samples were subjected to the variety of tests such as: pencil hardness test, resistance to scratching, bending test (T-test), paint adhesion, determining optimal method of measurement of the coating thickness. Findings: Polyurethane coatings are extremely hard and its strength exceeds strength of organic coating, but polyester coatings have proved to be superior in adhesion to the steel substrate. Micrometer method was found to be one of the best methods of measurement of the coating thickness. Research limitations/implications: Galvanized and coated materials can be successfully implemented for application which are cost effective and will not create a financial burden in the future. Practical implications: Wide range of application for industrial and household. Originality/value: Optimal configuration of the coatings properties in order to create best technological solutions.
