Abstract
Przedmiotem zgłoszenia jest sposób łączenia stopów aluminium z nadstopami niklu, przeznaczonych w szczególności do wytwarzania elementów narzędzi pomiarowych na przykład termopar, lutami na osnowie Al-Si, w procesie lutowania twardego z użyciem międzywarstwy utworzonej ze spoiwa o wyższej temperaturze topnienia, w którym metale (1 i 3), z których jeden stanowi nadstop niklu a drugi stop aluminium odtłuszcza się i oczyszcza się z tlenków a następnie łączy spoiwem (5) w postaci lutu, w procesie lutowania płomieniowego w temperaturze w zakresie 577 ÷ 620°C charakteryzuje się tym, że przed wytworzeniem trwałego połączenia lutowanego metali (1 i 3) na, uprzednio odtłuszczoną oraz oczyszczoną z tlenków, powierzchnię jednego z metali (1) nanosi się topnik, który następnie pokrywa się warstwą lutu, o temperaturze topnienia w zakresie 800 ÷ 830°C, która po zakrzepnięciu tworzy, naniesioną na jednym z metali, międzywarstwę metaliczną (2), a powierzchnię drugiego z metali (3) pokrywa się topnikiem (4), przy czym topnikiem (4) pokrywa się również powierzchnię międzywarstwy metalicznej (2).The subject of the application is a method of joining aluminum alloys with nickel superalloys, intended in particular for the production of measuring tool elements, e.g. thermocouples, Al-Si solder soldering, in the brazing process using an interlayer made of a binder with a higher melting point in which metals (1 and 3), one of which is a superalloy of nickel and the other aluminum alloy is degreased and cleaned of oxides and then joined with a binder (5) in the form of solder, in the process of flame soldering at a temperature in the range of 577 ÷ 620 ° C is characterized by before producing a permanent joint of soldered metals (1 and 3) on a previously degreased and cleaned of oxides surface of one of the metals (1), a flux is applied, which is then covered with a layer of solder, with a melting point in the range of 800 ÷ 830 ° C, which after solidification, it forms, applied on one of the metals, a metallic interlayer (2), and entrust The metal of the second metal (3) is covered with flux (4), with the flux (4) also covering the surface of the metallic interlayer (2).
