Description
Изобретение относитс к области получени металлокерамических изделий, в частности к видам термической обработки магнитных материалов .The invention relates to the field of metal-ceramic products, in particular, to the types of heat treatment of magnetic materials.
Известен способ термической обработки металлокерамических изделий из платинокобальтовых сплавов, заключающийс в нагреве, охлаждении и закалке.A known method for the heat treatment of cermet products from platinum-cobalt alloys, which consists in heating, cooling and quenching.
Предлагаемый способ отличаетс от известного тем, что с целью повышени магнитных свойств охлаждение с 1000 до 750°С провод т со скоростью 600-700°С в минуту, затем издели охлаждают до 500°С со скоростью 7-9°С в минуту и закаливают в воду.The proposed method differs from the known fact in order to increase the magnetic properties of cooling from 1000 to 750 ° C at a speed of 600-700 ° C per minute, then the products are cooled to 500 ° C at a speed of 7-9 ° C per minute and quenched in water.
Предлагаемый способ термической обработки осуществл етс следующим образом.The proposed heat treatment method is carried out as follows.
Издели из платинокобальтового сплава, полученные по известной технологии методом прессовани и спекани и имеющие плотность 15,0--15,1 г/см, подвергают нагреву до 1000°С с выдержкой при этой температуре в течение 1 час. Последующее охлаждение с 1000 до 750°С провод т со скоростью 600-700°С в минуту. Затем образцы охлаждают с 750 до 500°С со скоростью 7-9°С в минуту с последующей закалкой в воду. Всю термическую обработку провод т в водороде.Products made from a platinum-cobalt alloy, produced by pressing and sintering using a known technology and having a density of 15.0-15.1 g / cm, are heated to 1000 ° C and held at this temperature for 1 hour. Subsequent cooling from 1000 to 750 ° C is carried out at a speed of 600-700 ° C per minute. Then the samples are cooled from 750 to 500 ° C at a rate of 7-9 ° C per minute, followed by quenching in water. All heat treatment is carried out in hydrogen.
Предлагаемьга способ термической обработки обеспечивает повыщение магнитных свойств изделий из платинокобальтовых сплавов на 30% по сравнению с известным.The proposed method of heat treatment provides an increase in the magnetic properties of products from platinum-cobalt alloys by 30% compared with the known.
Свойства магнитов из платинокобальтового сплава, полученные после проведени термической обработки по предлагаемому и известному способам приведены в таблице.The properties of the magnets made from a platinum-cobalt alloy, obtained after carrying out heat treatment according to the proposed and known methods are given in the table.
