Покрытие формируется нанесением золь-гель композиции с уменьшенным размером кристаллитов на подложку с последующим нагреванием подложки до температуры, достаточной для образования покрытия из диоксида титана, содержащего кристаллы с размером кристаллитов менее 35 нм.Known methods for forming a coating of titanium dioxide (US Pat. RU 2483141, C23C 26, C09K 3/18, C03C 17/23, B60J 1, B05D 5, A61F 9/02, A61C 19, A47G 1. Coatings of titanium dioxide and methods of forming coatings of titanium dioxide with a reduced crystallite size. 2009. Sharma Pramod K.). The coating is formed by applying a sol-gel composition with a reduced crystallite size to the substrate, followed by heating the substrate to a temperature sufficient to form a titanium dioxide coating containing crystals with a crystallite size of less than 35 nm.
Недостатком прототипа является использование наноразмерных кристаллитов диоксида титана в составе золь-гель композиции для получения покрытия. Достижение наноразмерности требует специальной подготовки, в том числе использования достаточно мощных измельчительных аппаратов.The disadvantage of the prototype is the use of nanosized crystallites of titanium dioxide in the composition of the sol-gel composition to obtain a coating. Achieving nanoscale requires special training, including the use of sufficiently powerful grinding machines.
Настоящее изобретение направлено на упрощение способа нанесения защитного покрытия стали, что позволит сэкономить время и снизить ресурсозатраты.The present invention is aimed at simplifying the method of applying a protective coating of steel, which will save time and reduce resource costs.
Указанный технический результат достигается нанесением на стальную основу суспензии состава: H20+Na2SiO3+K0.06TiO2, с последующим высушиванием суспензии и термической обработкой в интервале температур 1100-1200°С.The specified technical result is achieved by applying to the steel base a suspension of the composition: H 2 0 + Na 2 SiO 3 + K 0.06 TiO 2 , followed by drying of the suspension and heat treatment in the temperature range 1100-1200 ° C.
Сущность заявленного изобретения поясняется следующим описанием.The essence of the claimed invention is illustrated by the following description.
Размер частиц наносимого покрытия выбран <150 нм, для увеличения сплошности получаемого покрытия и, как следствие, повышения антикоррозионной устойчивости. При размере частиц более 150 нм, покрытие становится большим по толщине, пористым и несплошным.The particle size of the applied coating is selected <150 nm, to increase the continuity of the resulting coating and, as a result, increase the corrosion resistance. With a particle size of more than 150 nm, the coating becomes large in thickness, porous and non-continuous.
Толщина покрытия определена из следующих соображений. Средняя толщина покрытия ≈75 мкм, обеспечивает высокую адгезию покрытия к стальной основе. Уменьшение толщины покрытия позволяет также снизить экономические и ресурсные затраты.The coating thickness is determined from the following considerations. The average coating thickness of ≈75 μm, provides high adhesion of the coating to the steel base. Reducing the thickness of the coating can also reduce economic and resource costs.
Пример осуществления технического решения. Стальную основу зачищают с помощью шлифовальной бумаги М40 и обезжиривают ацетоном. Суспензию готовят в весовом соотношении H20 : Na2SiO3 (в NaOHводн) : K0.06TiO2 = 1:0,05:0,05. Полученную суспензию наливают ровным слоем на стальную основу и высушивают в течение суток. Термическую обработку проводят с помощью газовой горелки (интервал температур 1100-1200°C).An example implementation of a technical solution. The steel base is cleaned with sanding paper M40 and degreased with acetone. The suspension is prepared in a weight ratio of H 2 0: Na 2 SiO 3 (in NaOH aq ): K 0.06 TiO 2 = 1: 0.05: 0.05. The resulting suspension is poured in an even layer on a steel base and dried overnight. Heat treatment is carried out using a gas burner (temperature range 1100-1200 ° C).
Эксплуатационные свойства полученного покрытия, нанесенным представленным способом следующие: прочность сцепления со стальной основой 1,2 МПа, прочность покрытия при изгибе стальной пластины - отслоение происходит при изгибе основы на 20°, химическая стойкость сталь - покрытие увеличилась в 2-3 раза.The operational properties of the obtained coating applied by the presented method are as follows: the adhesion to the steel base is 1.2 MPa, the strength of the coating when the steel plate is bent - peeling occurs when the base is bent by 20 °, the chemical resistance of the steel - coating increased by 2-3 times.
Сформированное таким способом оксидное титановое покрытие для защиты стали от коррозии и износа позволяет упростить процесс формирования защитного слоя на поверхности стали без ухудшения физико-химических и механических характеристик, обеспечивает экологическую безопасность, высокую термическую устойчивость, надежную защиту стали от коррозии и механического износа.The oxide titanium coating formed in this way to protect steel from corrosion and wear can simplify the process of forming a protective layer on the steel surface without impairing the physicochemical and mechanical characteristics, it provides environmental safety, high thermal stability, and reliable protection of steel from corrosion and mechanical wear.
