Reliability is one of the most important requirements for electric motor installations. Bearing assembly a common source failure motors. One main reasons such failures wear bearing seat end shield. This paper presents combined technology increasing durability bores shields made aluminum alloys. The technological concept that worn-out end-shield bore firstly restored by supersonic gas-dynamic sp...

New surface treatments are required to improve the resistance of high-voltage aluminium conductors corrosion and wear. This paper describes preparation ceramic coatings on wires by micro-arc oxidation (MAO) technology. The morphology, mechanical tribological properties, electrical resistivity, wear MAO-treated samples examined compared not only with untreated but also between use different curr...
