4 ГС Изобретение относитс к машино строению, в частности к химикотермической обработке высокоуглеродистых сталей в порошковых сред а именно дл повышени эксплуатационных характеристик .изделий из высокоуглеродистой стали, прммен мой в машиностроительной и металлургической промышленност х. Известен способ диффузионного хромировани стали У8 с использованием среды, содержащей 70% Gr, 29% ЫНдСе, в течение 6-12 ч при lOOO-lOSO C, который позвол ет получать карбидные хромовые слои толщиной 10-30 мкм tl3 Наиболее близким по технической сущности и достигаемому эффек ту вл етс состав дл диффузионного хромировани , содержащий, Мас.%: Cr2Oi 52; АК 18; , 27; 1; Z п 5; Fe 2. Процесс осуществл ют при 900 С IICO C в течение 4-8 ч« В результате термодиффузионной обработки стали У8 в известном со таве при в течение 4 ч на , поверхности упрочн емого издели формируетс диффузионный слой на основе карбидов хрома толщиной30 35 мкм С2Э.. : Однако износостойкость обрабат емых изделий недостаточно высока. . Целью изобретени вл етс повыше ние износостойкости обрабатываемых изделий. Указанна цель достигаетс тем,, что в состав дл хромировани изделий из высокоуглеродистых сталей, содержащий окись хрома, а роминий, окись алюмини , цинк и хлористый аммоний, дополнительно ввод т свинец при следующем соотношении ингредиентов , мас.%: хрома Алюми .ний Цинк Свинец Окись алюмини Хлористый аммоний р 1. Диффузионное Приме хромирование в предлагаемой порошковой среде осуществл етс при 900°С в течение 4ч в контейнерах с плавкими затворами. При этом формируетс диффузионный слой на основе карбидов хрома с поверхностной твердостью 13500-16000 Н/мм. Данные по обработке пoлy eнныx результатов представлены в таблице.4 GS The invention relates to mechanical engineering, in particular to the chemical heat treatment of high carbon steels in powder media, namely, to improve the performance characteristics of high carbon steel products used in the engineering and metallurgical industries. A known method of diffusion chromium plating of steel U8 using a medium containing 70% Gr, 29% YdSe for 6-12 hours at lOOO-lOSO C, which allows to obtain chromium carbide layers 10-30 µm thick tl3 The closest in technical essence and the effect achieved is a diffusion chromium compound containing, in wt.%: Cr2Oi 52; AK 18; , 27; one; Z p 5; Fe 2. The process is carried out at 900 C IICO C for 4-8 hours. As a result of the thermal diffusion treatment of steel U8, in a known manner for 4 hours, a diffusion layer based on chromium carbides with a thickness of 30 35 microns C2E ..: However, the wear resistance of processed products is not high enough. . The aim of the invention is to increase the wear resistance of the processed products. This goal is achieved by the fact that chromium-containing products from high carbon steels containing chromium oxide, and rumynium, alumina, zinc and ammonium chloride, are additionally injected lead in the following ratio of ingredients, wt.%: Chromium Aluminum Zinc Lead Alumina ammonium chloride p 1. Diffusion Primer chromium plating in the proposed powder medium is carried out at 900 ° C for 4 hours in containers with fusible closures. In this case, a diffusion layer based on chromium carbides with a surface hardness of 13500-16000 N / mm is formed. Data on the processing of the results are presented in the table.
