Изобретение относитс к металлургии , в частности к химико-термической обработке, и может быть использовано в машиностроении дл обработки штампового инструмента, предназначенного дл прессовани стеклокерамики .The invention relates to metallurgy, in particular to chemical heat treatment, and can be used in mechanical engineering for machining die tools intended for pressing glass ceramics.
Цель изобретени - уменьшение деформации изделий.The purpose of the invention is to reduce the deformation of products.
П р и м е р. Отожженные образцы из-стали 4х5МФС типа релаксационных колец диаметром 48 мм при сечении мм подвергают азотированию в газообразных продуктах разложени карбамида при 560°С в течение 2,5 ч. Дл сравнени изготавливают образцы, прошедшие термообработку и химико-термическую обработку по известной технологии: закалка в масло после аустенизации при , отпуск при 560°С 2 ч, азотирование при 560 С в течение 2,5 ч. Замер ют деформацию образцов в результате проведеНИН процесса, азотирпваин путем измерени на инструментальном микроскопе ширины прорези кольца. Результаты измерений приведены в таблице .PRI me R. Annealed samples of steel 4x5MPA type relaxation rings with a diameter of 48 mm with a cross section of mm are subjected to nitriding in the gaseous products of decomposition of urea at 560 ° C for 2.5 hours. For comparison, heat-treated and chemically-heat treated samples are made by hardening into oil after austenization at tempering at 560 ° C for 2 hours, nitriding at 560 ° C for 2.5 hours. Deformation of the samples as a result of the process, azothirvine, is measured by measuring the width of the slit using an instrument microscope oltsa. The measurement results are shown in the table.
Анализ данных, приведенных в таблице, показывает уменьшение короблений и деформаций при обработке по предлагаемому способу в среднем на 80-90% по сравнению с обра-боткой по известному способу.Analysis of the data in the table shows a decrease in warping and deformations during processing by the proposed method on average by 80-90% compared with processing by a known method.
