Изобретение относитс к области .машиностроени -и может быть применено нрн упрочнен и деталей с никель-фосфорным покрытием .The invention relates to the field of mechanical engineering, and nrn hardened and nickel-phosphorus-coated parts can be applied.
Известный способ термообработки деталей с никель-фосфорным покрытием состоит в том, что носле нанесени на предварительно закаленные :и отпущенные детали никель-фосфорного покрыти .их дополнительно отпускают при температуре 200-500°С.A known method of heat treatment of parts with a nickel-phosphorus coating consists in the fact that the coating on the previously hardened: and tempered parts of the nickel-phosphorus coating is additionally released at a temperature of 200-500 ° C.
Ио предлагаемому способу перед отпуском производ т закалку деталей с уже нанесенным никель-фосфорным покрытием. Это повышает пластичность покрыти и прочность сцеплени его с основным металлом.Before the proposed method, before tempering, the parts with the nickel-phosphorus coating already applied are hardened. This increases the ductility of the coating and its adhesion to the base metal.
Никель-фосфорное покрытие нанос т на обезжиренную и декапиро ваи:ную новерхиость детали известным способом. Детали после промывки и сушки закаливают с температуры, соответствующей марке стали, и затем отпускают при температуре 200-500°С и выдержке 2 час.A nickel-phosphorus coating is applied to the degreased and decaporative surface of the part in a known manner. After washing and drying, the parts are quenched from the temperature corresponding to the steel grade, and then let go at a temperature of 200-500 ° C and a holding time of 2 hours.
Способ применил дл инструментальных и среднеуглеродистых конструкционных сталей, температура закалки которых лежит в пределах 750-870°С, преимущественно дл обработки игл (.пробивных, швейных, трикотал ных и других), где после закалки механическа обработка не производитс .The method was applied to tool and medium carbon structural steels, the quenching temperature of which lies within 750-870 ° C, mainly for the processing of needles (punches, sewing, tricotal and others), where no mechanical treatment is performed after quenching.
Иосле обработки по предлагаемому способу никель-фосфорное покрытие имеет микротвердость не ниже 700 кгс/мм, а также повышенные характеристики пластичности и прочности сцеплени его с основным металлом.After processing by the proposed method, the nickel-phosphorus coating has a microhardness not lower than 700 kgf / mm, as well as enhanced characteristics of ductility and its adhesion to the base metal.
И р е д М е т изобретени And a reMet of the invention
Способ термической обработки деталей с иикель-фосфорным иокрытнем, включающий отпуск их при температуре 200-500°С, отличающийс тем, что, с целью повышени пластичности покрыти и прочности сцеплени его с основным металлом, перед отпуском производ т закалку деталей с нанесенным на них никель-фосфорным покрытием.The method of heat treatment of parts with nickel-phosphorus ikrytenya, including tempering them at a temperature of 200-500 ° C, characterized in that, in order to increase the plasticity of the coating and its adhesion to the base metal, nickel-coated parts are hardened before tempering phosphor coating.
