Аннотация: A limited set of reliable and technological solders based on palladium significantly complicates its use in the jewelry industry. When developing new solders it is important to take into account their manufacturability in casting and further processing. In addition, the melting point of the solder alloy should be lower than the metПоказать полностьюal of the article, which improves the casting conditions, the processability of the soldering and, usually, is achieved by introducing into the solder the corresponding alloying elements One of the promising areas of development of new branded solder compositions is the use of additional alloying components which form a continuous solid solutions of palladium and the elements forming the low-melting eutectic system without or with a minimum of intermetallic compounds. As components of the eutectic forming, silicon, boron, germanium and tin are most often used, since these components form a eutectic system on the phase diagram that can contribute to a decrease in the melting point of the solder alloy. The purpose of this work is the development of a new solder with a lowered relative to standard alloys based on palladium melting temperature and improved technological properties due to the use of a three-component system additionally doped with boron. Based on the developed by Professor Biron V.S. approach to the analysis of complex systems, an experimental testing of boron at a content of 2.2 to 3.1% by mass as a substance of the palladium forming the eutectic in solder alloys was carried out, and a methodology and technological regimes for obtaining a new solder alloy based on palladium with a temperature melting at 1200 °C. Conducted in the conditions of the jewelry production of JSC «Krasnoyarsk plant of non-ferrous metals» tests of this alloy gave positive results, on the basis of which the final composition of the new alloy was determined and patented. This technique was applied in the development of new compositions for precious metal alloys that are protected by Russian Eurasian patents.
