The use of organic insulation in the motor has temperature limitations, which limit its usage and further increase power density. In response to this issue, paper proposes a high-temperature resistant with micro-arc oxidation ceramic insulated wire, long-term service is able exceed 350°C. Firstly, generation conditions, formation principles, structural characteristics electrical wires were intr...

Al2O3-ZrO2 ceramic coatings were prepared on 6061 Al alloy by Micro Arc Oxidation (MAO) and Selective Laser Melting (SLM). Coatings MAO exhibit a porous structure progressive oxidation of the substrate as function processing time. Those made SLM are denser, although presence cracks is observed throughout their surface. XRD results suggest that coating consists m-ZrO2, t-ZrO2 γ-Al2O3 phases for ...

In this study, a high-hardness and wear-resistant ceramic coating was prepared on the surface of 319S aluminum alloy using micro-arc oxidation (MAO) technique. The effects pulse width, negative voltage, KOH concentration MAO were investigated, microhardness roughness measured. morphology, elemental distribution, phase composition analyzed SEM, EDS, XRD, digital microscopy. influence wear evalua...
