Description

Изобретение относитс  к химико-термической обработке металлов и сплавов, в частности к составам дл  диффузионног хромотитанировани . Предлагаемый состав может быть использован в машиностроительной , приборостроительной, хими- MecKOvl промышленности дл  повышени  износо-;жаро- и коррозионной стойкости инструмента, деталей машин и технологической оснастки. Известен состав .дл  хромотитанировани , содержащий титан 51,5-64,0; хром 17,5 - 24,0; окись алюмини  15,О21 ,25; гелогенид аммони  1,5-2,0; молибден 0,75-1,5; бор 1,О-2,О l. Наиболее близким к изобретению из и иестных  вл етс  состав, содержащий ком поненты, мас.: Окись титана1О-15 Окись хрома23-26 Алюминий9-27 Фтористый алюминий3-5 Окись алюмини Остальное 2 Процесс диффузионного хромотитанировани  в известном составе осуществл етс  при температурах 90O-ll6cfc в течение 2-8 ч. Так, при хромотитанировании в известном составе при 1О50 С в течение 6 ч сталей 45 и У8 формируютс  диффузионные слои толщиной 12-14 и 14-18 мкм соответственно. Недостатком известного состава дл  хромотитанировани   вл етс  низка  насыщающа  способность. Целью прюдлагаемого изобретени   вл етс  интенсификаци  процесса насыщени . Указанна  цель достигаетс  путем использовани  в известном составе дл  хромотитанировани  в качестве вещества-активизатора хлористого аммони  и введени  в со- став дополнительно окиси никел  при следуюшем соотношении компонентов, мас.%: Окись хрома21-23 Окись титана21-23 Окись никел 5-15 Порошок алюмини 18-20This invention relates to the chemical heat treatment of metals and alloys, in particular, to compositions for diffusion chromating. The proposed composition can be used in the machine-building, instrument-making, chemical- MecKOvl industry to increase the wear and heat and corrosion resistance of tools, machine parts and tooling. Known composition for chroma tination, containing titanium 51.5-64.0; chromium 17.5 - 24.0; alumina 15, O21, 25; ammonium helogenide 1.5-2.0; molybdenum 0.75-1.5; boron 1, O-2, O l. The closest to the invention from local is a composition containing components, wt .: Titanium oxide 1 O-15 Chromium oxide 23-26 Aluminum 9-27 Aluminum fluoride 3-5 Aluminum oxide Remaining 2 The process of diffusion chroming of the known composition is carried out at temperatures of 90 O-ll6cfc within 2–8 hours. Thus, during chromotitanation, diffusion layers 12–14 and 14–18 µm thick, respectively, are formed for 6 hours at 45 and U8 steels with a known composition at 1050C. A disadvantage of the known chromatising composition is the low saturation ability. The purpose of the present invention is to intensify the saturation process. This goal is achieved by using ammonium chloride as an activating substance in a known composition for chromotitanation and additionally adding nickel oxide into the composition with the following ratio of components, wt%: chromium oxide21-23 titanium oxide21-23 nickel oxide 5-15 aluminum powder 18-20
