Изобретение относитс к химико-термической обработке металлов и сплавов.This invention relates to the chemical heat treatment of metals and alloys.
Известен расплав дл борировани сталей в борсодержащих сол х, содержащий буру, порошок бора (1-15 вес.%) с добавкой галоидных солей шелочных и щелочноземельных металлов 13.Known melt for boron steels in boron-containing salts, containing borax, boron powder (1-15 wt.%) With the addition of halides of silk and alkaline earth metals 13.
Однако высока в зкость расплава при температурах 700-800°С вызывает снижение скорости насьлдени , унос расплава с обрабатываемыми издели ми и увеличение времени их отмывки.However, the high viscosity of the melt at temperatures of 700–800 ° C causes a decrease in the rate of saturation, the carry-over of the melt with the products being processed and an increase in the time of their washing.
Целью изобретени вл етс уменьше пте уноса расплава с обрабатываемыми издели ми и ускорение их отмывки.The aim of the invention is to reduce melt melt with processed products and accelerate their washing.
Эта цель достигаетс тем, что расилав дополннтелыю содержит метаборат натр , в качестве галоидных солей щелочных металлов хлористь й натрий ри следующем соотношении компонентов (в вес.%):This goal is achieved by the fact that additionally rasilav contains sodium soda metaborate, sodium chloride as the alkali metal halide salt has the following ratio of components (in weight%):
Метаборат натри 5О-54Metaborate sodium 5O-54
Хлористый натрий 40-45Sodium Chloride 40-45
БорОстальное,BorE rest,
В таблице представлены свойства изв€;стного ц пред.ложенного расплавов.The table presents the properties of the extruded melts.
При обработке стали У8 расплавом, со- держащим 54, 52 или 50% метабората Нс-три , 45, 43 или 40% хлорида натри , 1.5 или 10% бора, толщина покрыти , гголученного за 3 час при 800 С составл ет ссогветственыо 22, 53 или 80 мкм.When treating steel U8 with a melt containing 54, 52 or 50% metaborate Hc-three, 45, 43 or 40% sodium chloride, 1.5 or 10% boron, the thickness of the coating obtained in 3 hours at 800 ° C is equivalent to 22, 53 or 80 microns.
