    Tensiuni remanente în structurile superficiale formate la aliere prin metoda electroeroziunii în cîmp magnetic [Articol]
    (USARB, 2006) Pereteatcu, Pavel; Ursan, Boris
    În lucrare sînt prezentate rezultatele cercetărilor experimentale privind aprecierea tensiunilor remanente în straturile superficiale obţinute la alierea prin scântei electrice în cîmp magnetic. Rezultatele cercetărilor experimentale au demonstrat că pentru anumite valori ale vectorului inducţiei câmpului magnetic, mărimea tensiunilor remanente este cu mult mai mică decît în cazul alierii cu scînteie electrică în lipsa cîmpului.

    Utilizarea sculelor pentru rectificarea electrochimică (privire de sinteză) [Articol]
    (USARB, 2004) Ursan, Boris
    Progressive regenerative technologies are intensively used in repairing. Manufactures. To repair the work out surfaces of machine details. It is necessary to introduce new progressive high-effective processes of metal working for solving listed technological problems. One of then is the Method of Electrochemical abrasive greedings which is characterised with high efficiency and small deterioration of the tool. To get effective results when using the given method current conductive tools combining high conductivity and cutting properties of abrasive are required.

    Uzarea discurilor abrazive metalizate în procesul de rectificare electrochimică abrazivă [Articol]
    (USARB, 2004) Pereteatcu, Pavel; Ursan, Boris
    This research stresses upon the problem of reducing the wear of the abrasive disks in the process of abrasive electrochemical rectification. Thus the researches helped us to make some conclusions connected with the fact that physico-chemical properties and their technological peculiarities are improved in case of abrasive disks metallization. Metal working speed during the utilization of metal disks is growing while the specific wear is reducing.
