Abstract
Изобретение относитс к пайке , в частности, к составам припо дл пайки изделий из меди, латуни и никел , и может быть использовано при пайке медных проводников к корю электродвигател . Цель изобретени - повышение прочности, пластичности и коррозионной стойкости припо . Припой имеет следующий состав, мас. %: олово 25-60The invention relates to soldering, in particular, to solder compositions for soldering copper, brass and nickel products, and can be used when brazing copper conductors to a core of an electric motor. The purpose of the invention is to increase the strength, ductility and corrosion resistance of solder. Solder has the following composition, wt. %: tin 25-60

Solder is melted under a flux containing sodium and calcium salts. Yttrium is introduced into the brazing alloy in the form of a copper-yttrium alloy. The strength of the solder joint is on average 6 kgf / mm 2 , the relative elongation is in the range of 65-95%. The corrosion resistance determined by the corrosion current is 24 ohms. 1 tab.

. В св зи с тем,что медь и иттрий. Due to the fact that copper and yttrium
образуют эвтектику с температуройform eutectic with temperature
плавлени пор дка , последний вводитс в припой в виде лигатуры медь - иттрий.melting is on the order of which the latter is introduced into the braze in the form of a copper-yttrium ligature.
Введение в состав припо меди увеличивает его прочностные характеристики и коррозионную стойкость.The introduction of solder to copper increases its strength characteristics and corrosion resistance.
Присадка иттри действует как модификатор , измельча зерно, увеличива пластичность и прочность, .The yttrium additive acts as a modifier, grinding the grain, increasing plasticity and strength,.
Использование меди в количестве до 0,5% не приводит к заметному повышению прочности и коррозионной стойкости припо . Свыше 4% медь в припое не раствор етс и выпадает во вторую фазу,.что вызывает охрупчивание припо . Иттрий в количествах, меньших.The use of copper in an amount up to 0.5% does not lead to a noticeable increase in the strength and corrosion resistance of the solder. Over 4% of the copper in the solder does not dissolve and drops out in the second phase, which causes solder embrittlement. Yttrium in quantities smaller.
