“…The data shows that after a 600s experiment, the friction coefficient of Zn products is kept in the range of 0.06~0.10, and that of ZAM products is kept in the range of 0.08~0. 13. It shows that both products maintain excellent wear resistance, and the film layer is not damaged.…”

“…Ggalvanized layer on the Zn product protects the substrate from two aspects: 1) Protective effect of the galvanized layer on the physical barrier of the substrate; 2)Sacrificial anode protection of zinc Functional and Functionally Structured Materials V relative to iron. The electrode position of zinc is -0.762V, while the electrode position of iron is -0.44V [13,14]. It is easy to form galvanic cells at local locations, and active dissolution of zinc occurs, as shown in Eq.…”

The wear resistance and corrosion resistance of chromium-free fingerprint-resistant pure zinc and Zn-Al-Mg coated cold-rolled steel sheets were studied by micro-friction wear experiments and neutral salt spray experiments. Two products are worn for a long time with a large load (5N load, 50 times abrasion), the depth of wear zone of Zn-Al-Mg coating product is 9% shallower than that of pure zinc coating product, and the width of wear zone is 15.4% smaller. Both products still meet the requirements of use after corrosion. The corrosion resistance of two products after degreasing treatment was significantly reduced. The Mg and Al in the Zn-Al-Mg coating can hinder the progress of corrosion, so it has better corrosion resistance.

“…The literatures offer a significant number of articles on the technology of applying varnish coatings e.g., [5,6], as well as current activities and technological achievements in the field of intelligent composite nano-coatings [7] and new material components [8]. These activities, in particular the hardening methods [9] and especially the UV methods [10], have improve the resistance of coatings to external mechanical factors [11], which is important in the case of automotive vehicle operations [12].…”

Assessment of Selected Properties of Varnish Coating of Motor Vehicles

et al. 2021

The technology and methods of testing the properties of varnish coatings used in motor vehicles are constantly and successfully developed. However, in the case of automotive varnish renovation coatings used in the repair of car bodies, the problem of fitting the quality of these coatings to the quality and current condition of the coating applied to undamaged vehicle components is not definitely solved. The main goal of the research was to determine the thickness and gloss distribution of the varnish coatings. The thickness and gloss of the varnish coating on the entire body of the vehicle were measured. Classical methods of assessing these properties were used. Defects in the renovation coating were also simulated, to show their negative impact on the varnish quality. The performed tests allowed for development of a procedure and algorithm for evaluation of the quality of the car’s renovation coating after the repair of the car body. The proposed procedure, expressed with the presented algorithm, allows to fit the obtained renovation coating to the quality and condition of the coating manufactured in factory on the car body in the range of its thickness up to 270 µm and gloss in the range of 5–90 GU. The developed procedure for the assessment of renovation coatings can be used in workshops that repair vehicle bodies. This will allow to improve the quality of renovation coatings and bring their properties, such as thickness or gloss, closer to those applied to the vehicle’s body at the factory.
