Изобретение относитс к разработке сплавов на основе свинца, преДна-31на1чеННых дл Примеиени в качестве |кор1розионностойко:го покрыти , работаюнгего в серной кислоте с кОНдентращией до 80% и температурой до 100°С при освшщавании хиашчеокой аппарату ры.The invention relates to the development of alloys based on lead, which is superior for use as a corrosion-resistant coating, operating in sulfuric acid with a concentration of up to 80% and temperature up to 100 ° C upon drying with a hygiene apparatus.
Известен Оплав а основе свинца, содержащий олово и кадмий.Known Oplav and lead-based, containing tin and cadmium.
Предлагаемый сплав отличаетс от известного наличием в нем цери и более ннзкнм содержанием олова, что способствует повы шению коррозионной стойкости оплаеа.The proposed alloy differs from that known for the presence of cerium in it and, more generally, the tin content, which contributes to an increase in the corrosion resistance of opal.
