Abstract
Description
Изобретение относится к обработке металлической поверхности, в частности к фосфатированию, и может быть использовано для защиты металлов от коррозии в любой отрасли машино- и приборостроения, а также перед нанесением лакокрасочных покрытий. The invention relates to the treatment of a metal surface, in particular to phosphating, and can be used to protect metals from corrosion in any industry of machine and instrument engineering, as well as before applying coatings.
Известен способ нанесения фосфатных пленок (Хаин И.И. Теория и практика фосфатирования металлов. Л.Химия.-1973, с.93-97), заключающийся в механической очистке поверхности, обезжиривании в щелочном растворе, промывке в проточной и дистиллированной воде с последующим фосфатированием. Однако фосфатное покрытие на сплавы, содержащие свыше 12% хрома, имеет низкую адгезию к поверхности, а на сплав ЭП-202 (ХН67МВТЮ), содержащий
N 4,0 6,0
Mo 4,0 5,0
Fe не более 4
C не более 0,08
Si не более 0,6
М не более 0,5
Cr 17 20
Ni основа
Ti 2,2 2,8
Al 1,0 1,5
покрытие не наносится совсем.A known method of applying phosphate films (Khain II Theory and practice of phosphating metals. L. Chemistry.-1973, p.93-97), which consists in mechanical cleaning of the surface, degreasing in an alkaline solution, washing in running and distilled water, followed by phosphating. However, the phosphate coating on alloys containing more than 12% chromium has low adhesion to the surface, and on the EP-202 alloy (KhN67MVTYu) containing
N 4.0 6.0
Mo 4.0 5.0
Fe no more than 4
C no more than 0.08
Si no more than 0.6
M no more than 0.5
Cr 17 20
Ni base
Ti 2.2 2.8
Al 1.0 1.5
the coating is not applied at all.
Перед авторами стояла задача нанесение защитного фосфатного покрытия на изделия из указанного сплава в качестве подслоя перед нанесением лакокрасочных покрытий. The authors were faced with the task of applying a protective phosphate coating on products from the specified alloy as a sublayer before applying coatings.
Эта задача решена путем активирования поверхности изделий перед фосфатированием. При этом активирование проводят в 5 7% растворе аминов в органическом растворителе при температуре 35 40oC в течение 10 15 мин. В качестве амина используют 4-амино-2,2,6,6-тетраметилпиперидин, а в качестве органического растворителя смесь N-метилпирролидона с бутиловым спиртом в соотношении 1:1.This problem is solved by activating the surface of the products before phosphating. When this activation is carried out in a 5 7% solution of amines in an organic solvent at a temperature of 35 40 o C for 10 15 minutes 4-amino-2,2,6,6-tetramethylpiperidine is used as an amine, and a mixture of N-methylpyrrolidone with butyl alcohol in a 1: 1 ratio is used as an organic solvent.
Предлагаемый способ осуществлялся следующим образом: поверхность изделия зачищали наждаком от ржавчины, окалины, обезжиривали 20% раствором соды при комнатной температуре в течение 5 минут, промывали в проточной и дистиллированной воде, активирования в 5 7% растворе аминов в органическом растворителе. В качестве аминов использовали моноэтаноламин, пиридин и 4-амино-2,2,6,6-тетраметилпипередин, а в качестве органического растворителя-смесь N-метилпирролидона с бутиловым спиртом в соотношении 1:1. The proposed method was carried out as follows: the surface of the product was erased of rust, scale, degreased with a 20% soda solution at room temperature for 5 minutes, washed in running and distilled water, activated in a 5 7% solution of amines in an organic solvent. Monoethanolamine, pyridine and 4-amino-2,2,6,6-tetramethylperedin were used as amines, and a mixture of N-methylpyrrolidone with butyl alcohol in a 1: 1 ratio was used as an organic solvent.
Активирование проводили при температуре 35±2oC в течение 10-15 мин. Затем изделие промывали дистиллированной водой и фосфатировали в растворе (вес. ):
соль "Мажеф" 40
фтористый натрий 10
вода остальное
при температуре 95 98oC в течение 20 30 мин. После нанесения фосфатного подслоя наносят лакокрасочное покрытие по известной технологии.Activation was carried out at a temperature of 35 ± 2 o C for 10-15 minutes Then the product was washed with distilled water and phosphated in solution (wt.):
Majef salt 40
sodium fluoride 10
water rest
at a temperature of 95 98 o C for 20 30 minutes After applying the phosphate sublayer, a paint coating is applied according to known technology.
Эффективность предлагаемого способа фосфатирования поверхности изделий из сплава с большим содержанием хрома и никеля оценивали по прочности сцепления покрытия с основой и по краевому углу смачивания. The effectiveness of the proposed method for phosphating the surface of alloy products with a high content of chromium and nickel was evaluated by the adhesion strength of the coating to the base and by the wetting angle.
Как видно из результатов исследования, покрытие, полученное с использованием предварительного активирования изделий в растворе 4-амино-2,2,6,6-тетраметилпипередина, обладает высоким сцеплением и лучшей смачиваемостью поверхности по сравнению с покрытиями, полученными после активирования растворами моноэтаноламина и пиридина. As can be seen from the results of the study, a coating obtained using pre-activation of products in a solution of 4-amino-2,2,6,6-tetramethylperedin has high adhesion and better surface wettability compared to coatings obtained after activation with solutions of monoethanolamine and pyridine.
Температура активирования 35±2oC подбирали опытным путем. Изменение температуры выше или ниже указанных пределов приводило к ухудшению сцепления покрытия с основой.The activation temperature of 35 ± 2 o C was selected empirically. Changes in temperature above or below the specified limits led to a deterioration in adhesion of the coating to the substrate.
Таким образом, авторы решили задачу нанесения защитного фосфатного покрытия на изделия из сплава с высоким содержанием хрома и никеля с последующим нанесением лакокрасочных покрытий. Thus, the authors solved the problem of applying a protective phosphate coating on alloy products with a high content of chromium and nickel, followed by applying coatings.
