Abstract

Inventia se refera la procedeele de lipire a aliajelor, in particular la un procedeu de lipire prin aliere cu scantei a aliajelor dure sinterizate si a otelurilor carbon. Procedeul, conform inventiei, include depunerea pe suprafata de lipit, prin aliere cu scantei, la o frecventa a impulsurilor de 200…500 Hz si durata de 200…400 µs, a unui strat de acoperire intermediar, care nu este un material de lipit, spoirea si lipirea ulterioara a stratului obtinut cu aliaje usor fuzibile, cu utilizarea unui flux de colofoniu.The invention relates to the processes of bonding alloys, in particular to a process of bonding by sparks alloying of hard sintered alloys and carbon steels. The process, according to the invention, includes depositing on the soldering surface, by sparks alloying, at a pulse frequency of 200 ... 500 Hz and the duration of 200 ... 400 µs, of an intermediate coating layer, which is not a soldering material, subsequent spraying and bonding of the layer obtained with easily fusible alloys, using a rosin flow.
