6. Magnetron Sputtering of Nanocomposite Carbide Coatings for Electrical Contacts
Sammanfattning : Today’s electronic society relies on the functionality of electrical contacts. To achieve good contact properties, surface coatings are normally applied. Such coatings should ideally fulfill a combination of different properties, like high electrical conductivity, high corrosion resistance, high wear resistance and low cost. LÄS MER
7. The effect of microstructure and temperature on the atmospheric corrosion of Mg-Al alloys
Sammanfattning : The NaCl-induced atmospheric corrosion behavior of the Mg-Al alloy AM50 produced by rheo-casting (RC) and high pressure die casting (HPDC) techniques was studied in the laboratory. The exposures were performed at 95% RH in the absence and presence of 400 ppm CO2 at 22, 4 and -4ºC. In parallel, 99.97%Mg was investigated as reference. LÄS MER
8. The Role of Microstructure in the Atmospheric Corrosion of Selected Light Alloys and Composites
Sammanfattning : Magnesium-aluminum (Mg-Al) alloys, Mg-based metal matrix composites (MMCs) and Al alloys are among the best material candidates for future lightweight solutions. However, the use of these materials is limited by a number of issues, including the ability to resist corrosion. LÄS MER
9. Corrosion testing of heat exchanger tubing
Sammanfattning : Heat exchanger tubes are commonly made from stainless steel.In a heat exchanger both the process fluid and the cooling orheating media can be corrosive. It is therefore important to beable to select materials that do not suffer from corrosion.Current methods in this area, however, suffer from limitationsand shortcomings. LÄS MER
10. Beyond Breakaway Corrosion: Secondary Corrosion Protection of Iron-based Alloys
Sammanfattning : Metallic materials intended for high temperature applications must resist both mechanical and environmental degradation. The ability to withstand corrosion is an important aspect of high temperature materials and is of major concern in, for example, heat and power production. LÄS MER
