Abstract
Inventia se refera la un inel format din pulberi metalice sinterizate pe baza de ter, avînd pulbere de cupru între 2...10%, pulbere de grafit între 0,1 si 10% si restul fier, materialul rezultat avînd o porozitate între 20 si 30% determinata de introducerea în mare pulberi, în timpul operatiei de amestecare, a unei cantitati între 0,1 si 5,5% stearat de zinc. Inelul prezinta rezistenta sporita la uzura datorita frecarii cursorului si la actiunea agresiva datorita aciditatii baii de tratare în timpul filarii, reducînd utilizarea pulberii de otel inoxidabil.The invention relates to a ring formed from terra-based sintered metallic powders having a copper powder of between 2 and 10%, a graphite powder between 0.1 and 10% and the remainder iron, the resulting material having a porosity of between 20 and 30% due to the high particulate injection during the mixing operation of an amount of between 0.1 and 5.5% of zinc stearate. The ring has increased wear resistance due to friction and aggressive action due to the acidity of the treatment bath during filing, reducing the use of stainless steel powder.
