Изобретение относитс к области обработки металлов перед нанесением покрытий.This invention relates to the field of metal processing before coating.
Известен способ подготовки изделий nepe.i наиесеНием гальванических покрытий окислени изделИЙ в среде перегретого пара при 550-600°С.A known method of preparing products nepe.i by the presence of electroplating coatings for oxidation of products in an environment of superheated steam at 550-600 ° C.
Предлагаемый способ отличаетс от известного тем, что с целью увеличени прочности сцеплени изделий из черных металлов с полимерным покрытием окисление провод т при 440-500°С в течение 45-60 мин.The proposed method differs from the known one in that in order to increase the adhesion strength of ferrous metal products with a polymer coating, the oxidation is carried out at 440-500 ° C for 45-60 minutes.
Так, например, образцы из стали 45 в виде цилиндров диаметром 25 мм и длиной 50 мм окисл ют в среде вод ного пара при 440°С в течение 15-190 мин. Температура поверхности образца в момент на-несени покрыти из вторичного лоликапроамида литьем под давлением составл ет 280°С. При этом прочность сцеплени при сдвиге повышаетс с 428 кгс/см- (15 мин окислени ) до 532 кгс/см (45 мин окислени ). Дальнейшее окисление проктически не вли ет на прочность сцеплени покрыти при сдвиге.For example, samples of steel 45 in the form of cylinders with a diameter of 25 mm and a length of 50 mm are oxidized in an environment of water vapor at 440 ° C for 15-190 minutes. The surface temperature of the sample at the time of deposition of the secondary lolicaproamide coating by injection molding is 280 ° C. At the same time, the shear adhesion strength increases from 428 kgf / cm- (15 min of oxidation) to 532 kgf / cm (45 min of oxidation). Further oxidation does not proctically affect the adhesion strength of the coating during shear.
Окисна пленка, получаема на издели х из черных металлов по предлагаемому способу , обладает высокой прочностью сцеплени к основному металлу и полимерному покрытию .The oxide film obtained on ferrous metal products according to the proposed method has a high adhesion strength to the base metal and polymer coating.
Предмет изобретени Subject invention
Способ подготовки изделий перед нанесением покрыти окислением в среде вод ного пара при высоких температурах, отличающийс тем, что, с целью увеличени прочности сцеплени изделий из черных металлов с полимерным покрытием, окисление провод т при 440-500°С в течение 45-60 мин.The method of preparing products before applying the coating by oxidation in an environment of water vapor at high temperatures, characterized in that, in order to increase the adhesion strength of ferrous metals with a polymer coating, the oxidation is carried out at 440-500 ° C for 45-60 minutes.
