Abstract
Przedmiotem zgłoszenia jest sposób łączenia stopów aluminium z materiałami kompozytowymi na osnowie grafitu metodą lutowania miękkiego. Powyższe połączenia stosowane są w urządzeniach przewodzących prąd elektryczny, a w szczególności w budowie odbieraków prądu pojazdów szynowych w którym to sposobie materiały, z których jeden stanowi stop aluminium a drugi kompozyt na osnowie grafitu odtłuszcza się i oczyszcza się z tlenków a następnie łączy się spoiwem w postaci lutu, w procesie lutowania miękkiego w temperaturze w zakresie 183 ÷ 200°C. Sposób charakteryzuje się tym, że przed wytworzeniem trwałego połączenia lutowanego miękkiego materiałów, na uprzednio odtłuszczoną oraz oczyszczoną z tlenków, powierzchnię jednego z materiałów nanosi się metodą natryskiwania cieplnego warstwę metaliczną z proszku metalu, która po procesie natryskiwania tworzy, naniesioną na tym metalu, międzywarstwę metaliczną, a na powierzchnię drugiego materiału nanosi się w procesie natryskiwania cieplnego strukturę złożoną z trzech powłok metalicznych, nałożonych jedna na drugą, stanowiącą międzywarstwę metaliczną drugą, przy czym przed wytworzeniem trwałego połączenia lutowanego obie międzywarstwy pokrywa się topnikiem.The subject of the application is a method of joining aluminum alloys with composite materials on a graphite matrix by soft soldering. The above connections are used in electrically conductive devices, in particular in the construction of current collectors for rail vehicles, in which way materials, one of which is an aluminum alloy and the other composite on a graphite matrix, are degreased and cleaned of oxides and then combined with a binder in the form of solder, in the process of soft soldering at a temperature in the range of 183 ÷ 200 ° C. The method is characterized by the fact that before producing a permanent connection of soft solder materials, previously degreased and cleaned of oxides, the surface of one of the materials is applied by means of thermal spraying a metal layer of metal powder, which after the spraying process forms a metallic interlayer on this metal , and the surface of the second material is applied by means of a thermal spraying process of a structure consisting of three metallic coatings applied one on top of the other, constituting the second metallic interlayer, with both interlayer being covered with flux before forming a permanent soldered joint.
