Description

Согласно насто щему изобретению, предлагаетс  ускоритель дл  азотизации стальных деталей, состо щий из перекиси марганца и окиси титана с анилином или водным раствором кле  дл  св зи.According to the present invention, an accelerator is proposed for nitriding steel parts consisting of manganese peroxide and titanium oxide with aniline or an aqueous solution of adhesive for bonding.

Ускоритель представл ет собой смесь 40 г 1102 + 4 г МпО2+100 г Сб HS-NH,, котора  наноситс  на детали окунанием. Состав действует как ускоритель до получени  сло  нитридов толщиной и,24 мм в течение 4 часов и дает ускорение азотизации дл  нитросло  35ХМА в два раза, при режиме азотизации 520° - 2 часа 30 минут, час, 590° без тока NHg - 30 минут. Налет от состава стираетс  с деталей после азотизации соверщенно легко.The accelerator is a mixture of 40 g 1102 + 4 g MpO2 + 100 g Sb. HS-NH, which is applied to the parts by dipping. The composition acts as an accelerator to obtain nitride layers with a thickness of and 24 mm for 4 hours and gives acceleration of nitriding for nitro 35XMA double, with a nitriding regime of 520 ° - 2 hours 30 minutes, an hour, 590 ° without current NHg - 30 minutes. The coating from the composition is erased from the parts after nitriding is completely easy.

По отдельности МпО2, ТЮо и СоН5МН2 никакого ускорени  азотизации не вызывают. На процесс ускорени , по указанию изобретател , вли ет кислород, который выдел етс  при температуре выше 530 за счет разложени  MnOj, причем благопри тное действие этого кислорода, св зывающего в воду вредный водород диссоциированного NHg, наблюдаетс  только в присутствии TiOs.Separately, MnO2, TiOo, and CoH5MH2 do not cause any nitriding. The acceleration process, as instructed by the inventor, is influenced by oxygen, which is released at temperatures above 530 due to decomposition of MnOj, and the beneficial effect of this oxygen, which binds the harmful hydrogen of dissociated NHg into water, is observed only in the presence of TiOs.

Ускоритель применим во всех случа х , когда требуетс  глубина азотизации до 0,24 мм. Качество азотизации с ускорителем, по даннЕз1м изобретател , удовлетворительное (твердость 1100 по Виккерсу, переход к сердцевине -плавный).The accelerator is applicable in all cases where a nitriding depth of up to 0.24 mm is required. The quality of nitriding with an accelerator, according to the inventor, is satisfactory (1100 Vickers hardness, transition to the core is smooth).

Вместо анилина может быть применен водный раствор кле .Instead of aniline, an aqueous solution of glue can be used.

Предмет изобретени .The subject matter of the invention.

Ускоритель дл  азотизации, отличающийс  тем, что он состоит из смеси перекиси марганца и окиси титана с анилином или водным раствором кле  дл  св зи, какова  смесь наноситс  на подлежащие азотизации детали методом окунани .An accelerator for nitriding, characterized in that it consists of a mixture of manganese peroxide and titanium oxide with aniline or an aqueous solution of an adhesive for bonding, which mixture is applied to the parts to be nitrided by dipping.
