Wear Behavior of Composites and Nanocomposites: A New Approach
The expulsion of material from either of two strong surfaces in relative movement is termed as wear. Wear can also be defined as surface damage, because of material relocation with no net change in weight or volume. It happens as a natural result and for the most part through surface interactions at severities. It is a system response and is not a material property. Interface wear is firmly com...
متن کاملZrB2-CNTs Nanocomposites Fabricated by Spark Plasma Sintering
ZrB₂-based nanocomposites with and without carbon nanotubes (CNTs) as reinforcement were prepared at 1600 °C by spark plasma sintering. The effects of CNTs on the microstructure and mechanical properties of nano-ZrB₂ matrix composites were studied. The results indicated that adding CNTs can inhibit the abnormal grain growth of ZrB₂ grains and improve the fracture toughness of the composites. Th...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولWear of Polytetrafluoroethylene Nanocomposites: Effects of Dispersion, Crystallinity and Toughness
Solid lubricants are commonly found in applications where more traditional lubrication techniques are undesirable or precluded. Polytetrafluoroethylene (PTFE) is an attractive solid lubricant, but high wear rates limit its use. While nanofillers have been found, in some cases, to provide wear resistance without introducing other detrimental effects, the mechanisms of wear resistance remain uncl...
متن کاملmicrostructure and mechanical properties of al2o3-sic nanocomposites with 0.05% mgo and different sic volume fraction
abstract: in this study, al 2 o 3 –sic nanocomposites have been fabricated by mixing of alumina powder containing 0.05% weight magnesium oxide and silicon carbide nano powders, followed by hot pressing at 1650 0 c. the mechanical properties of al 2 o 3 -sic nanocomposites containing different volume fraction (2.5, 5, 7.5, 10 and 15%) of nano scale sic particles were investigated and compared wi...
