INTRODUCTION. Graphene has attracted attention worldwide and is considered a promising material for industrial appliions. Before the exfoliation of graphene with Scotch tape was reported in 2004 , several groups had exfoliated graphite to thin platelets [2, 3], and identified ‘single-layer graphite’ on noble metal surfaces as grown by chemical vapor deposition (CVD) .
High temperature caused by copper core would have a certain impact on the performance of XLPE insulation during the long running process of the cable. In this paper, the XLPE/PVC cable running for 17years was investigated by using thermal analysis, microstructure analysis, mechanical property analysis and dielectric properties analysis. The influences of long-term operation for the physical
During the early nineteenth century, Englishman Henry Maudslay produced the method of screw manufacture still in use today. His machine was the first power-driven, screw-cutting lathe. In the United States, at the same time, David Wilkinson also built a screw-cutting lathe and was awarded the first American screw patent.
Advanced ceramics coine high strength and toughness with extreme hardness to give excellent wear resistance. Materials such as silicon nitride and sialon and silicon carbide also have excellent high-temperature properties and are resistant to corrosion by many acids and alkalies which allows them to find numerous wear resistance appliions.
