Description
Изобретение относитс к химикотермичес1 ой обработке металлов и сплавов и может быть использовано в машиностроении, приборостроении, металлургической и других отрасл х промышленности .The invention relates to the chemical-heat treatment of metals and alloys and can be used in mechanical engineering, instrument-making, metallurgical and other industries.
Наиболее близким к предлагаемому вл етс состав дл диффузионного цинковани меди, содержащий порошки цинка, окиси алюмини и хлористого аммони Ц , мас.%:The closest to the present invention is a composition for diffusive galvanizing of copper containing powders of zinc, alumina and ammonium chloride C, wt.%:
50%Zn 4- 50% Zn 4-
После насыщени олов нистых бронз в известном составе при в течение 4 ч на них формируетс диффузионный цинковый слой с микротвер .достью 190-210 кг/мм.After saturating the tin bronze in a known composition, a diffusion zinc layer with a micro-hole with a length of 190-210 kg / mm is formed on them for 4 hours.
Цель изобретени - повышение поверхностной твердости олов нистых бронз. The purpose of the invention is to increase the surface hardness of tin bronze.
Указанна цель достигаетс тем, что порошкова смесь, содержаща цинк, окись алюмини и хлористый аммоний , дополнительно содержит медь и никель при следующем соотношений ингредиентов, мас..%:This goal is achieved by the fact that the powder mixture containing zinc, alumina and ammonium chloride, additionally contains copper and nickel in the following ratios of ingredients, wt.%:

Цинкование в составе проводитс при в течение 4 ч. Galvanizing in the composition is carried out for 4 hours.
15 Результаты обработки приведены в таблице.15 The processing results are shown in the table.
Таким образом при химико-термической обработке олов нистых бронз из предлагаемого состава их поверх20 ностна твердость увеличиваетс на 30%.Thus, during the chemical heat treatment of tin bronze from the proposed composition, their surface hardness increases by 30%.
аммоний, отличающийс тем, что, с целью повышени поверхностной твердости олов нистых бронз, он дополнительно содержит медь и никель .при следукхцем соотношении, мае.%:ammonium, characterized in that, in order to increase the surface hardness of tin bronze, it additionally contains copper and nickel. when following the ratio, in May.%:
