Description
Изобретение относитс к ускоренным коррозионным испытани м лакокрасочных покрытий и может быть использовано как дл контрол защитных свойств покрытий, так и дл оценки состава покрыти и способов его нанесени .The invention relates to accelerated corrosion testing of paint coatings and can be used both to control the protective properties of coatings and to evaluate the composition of the coating and its coating methods.
Известен способ контрол качества лакокрасочных покрытий на металлах при ускоренных испытани х, заключающийс в том, что серию образцов в виде подложек с покрытием выдерживают в коррозионной среде одинаковое врем , затем удал ют покрытие и оценивают состо ние подложки по весовым потер м 1.A known method for controlling the quality of paint coatings on metals under accelerated testing, consists in that a series of samples in the form of coated substrates are kept for the same time in a corrosive environment, then the coating is removed and the state of the substrate is evaluated by weight loss 1.
Недостатком этого способа вл етс низка точность оценки, что обусловлено большой погрешностью весового метода.The disadvantage of this method is the low accuracy of the estimate, which is caused by the large error in the weight method.
Цель изобретени - повышение точности контрол качества лакокрасочных покрытий.The purpose of the invention is to improve the accuracy of quality control of paint coatings.
Указанна цель достигаетс тем, что в способе контрол качества лакокрасочных покрытий на металлах при ускоренных испытани х, заключающемс в том, что серию образцов в виде подложек с покрытием выдерживают в коррозионной среде, затем удал ют покрытие и оценивают состо ние подложки.This goal is achieved by the fact that in the method of controlling the quality of paint coatings on metals under accelerated testing, the series of samples in the form of coated substrates are kept in a corrosive environment, then the coating is removed and the state of the substrate is evaluated.
врем выдержки измен ют от образца к образцу, после удалени покрыти подложку погружают в электролитическую чейку со вспомогательным элект- . родс и, увеличивают потенциал подложки , определ ют потенциал по влени анодного тока и по изменению этого потенциала от времени выдержки суд т о качестве покрыти .the exposure time varies from sample to sample, after removing the coating, the substrate is immersed in an electrolytic cell with an auxiliary elec- tric. rods and, increase the substrate potential, determine the potential for the occurrence of the anode current, and judging by the quality of the coating, by the variation of this potential from the exposure time.

Способ основан на том, что потенциал по влени анодного тока пбдложкй увеличиваетс с увеличением врейени выдержки в коррозионной среде при недостаточном качестве лакокрасочного The method is based on the fact that the potential for the occurrence of anode current pbdlokky increases with an increase in the exposure time in a corrosive environment with insufficient quality of paintwork.
15 покрыти . Это обусловлено тем, что чем больше первоначальных продуктов коррозиии образуетс на подложке, тем больше торможение процесса активировани подложки и, соответственно, зна20 чение потенциала по влени анодного тока, что косвенно характеризует проницаемость покрыти дл коррозионной среды и, следовательно, отсутствие коррозионной устойчивости покрыти .15 coverings. This is due to the fact that the more initial corrosion products are formed on the substrate, the greater the deceleration of the activation process of the substrate and, accordingly, the value of the potential of anode current, which indirectly characterizes the permeability of the coating to the corrosive environment and, consequently, the lack of corrosion resistance of the coating.
