Description

Результаты диффузионного насыщени  представлены в табл. Дл  изготовлени  предложенной смеси использовались: технический карбид бора ГОСТ 3641-71, фтористый натрий марки «Ч ГОСТ 4463- 66, пылевидный кварц марки КП-Ш. При .насыщении из известного состава (55% карбид бора, 22% перефилит, 17% огарок, 6% фтористый нат.рий) при темлературе 900° С в течение 4 ч ка стали 45 формируетс  боросилицированный слой толщиной 155 мкм. Из приведенных результатов следует, что (Насыщающа  способность предложенного состава в 1,3-1,5 раза выще, чем известного . Форму vT а изобретени  Состав дл  борооилицировани  стальных изделий, содержащий карбид бора, фтористый натрий, и кремнийсодержащее вещество, отличающийс  тем, что, с целью увеличени  активности насыщающей смеси, в качестве кремнийсодержащего вещества он содержит пылевидный кварц при следующих соотношени х компонентов , мае. ,%: Фтористый натрий2-10 Пылевидный КварцЭЗ-53 Карбид бораОстальное; Источники информации, прин тые во внимание при экспертизе: 1. Авторское свидетельство СССР № 450000, кл. С 23 С 9/04, 1972. 2. Авторское свидетельство СССР по за вке № 2675913, кл. С 23 С 9/04, 1978.The results of diffusion saturation are presented in Table. For the manufacture of the proposed mixture were used: technical boron carbide GOST 3641-71, sodium fluoride of the brand “CH GOST 4463-66, dust-like quartz of the brand KP-Sh. At saturation of a known composition (55% boron carbide, 22% perefilit, 17% cinder, 6% sodium fluoride) at a temperature of 900 ° C, a borosilicated layer with a thickness of 155 µm is formed within 4 hours of steel 45. From the above results, it follows that (the saturation ability of the proposed composition is 1.3-1.5 times higher than the known. Form vT of the invention Composition for boronization of steel products containing boron carbide, sodium fluoride, and a silicon-containing substance, characterized in , in order to increase the activity of the saturating mixture, as a silicon-containing substance, it contains powdered quartz in the following ratios of components, May.,%: Sodium fluoride 2-10 Dusty QuartzEZ-53 Boron carbide Rest; Sources of information, s into consideration in the examination:. 1.
