1. A study was made of the ductility of semifinished products in 6–15% alumina SAP materials at temperatures of 20–550°C. The elongation of SAP was found to vary anomalously as a function of temperature. It was established that the elongation an

Hard wear-resistant coatings require excellent oxidation resistance for high-speed machining operations. Moreover, the oxide formed is integral to the frictional behavior and therefore the success of the coating. The oxidation behavior of TiAlN/VN na

The oxidation resistance of ductile irons alloyed with aluminium in the range from 0.08 to 6.16 wt.% has been investigated by heating at 550 °C for periods up to 1270 h. Examination by light and SEM microscopy and EPMA indicated that two quite disti

The addition of beryllium to Al-Mg alloys is known to cause a dramatic decrease in oxidation; however, the mechanism behind this protective effect is not yet fully understood. To aid in finding an alternative to the toxic Be, a fundamental study of B

AZ91 magnesium alloys containing 0.3% Ca and 0.1% Y were cast, and their oxidation behavior was investigated between 425 and 600 °C in atmospheric air to examine roles of Ca and Y during oxidation. During casting, Ca formed Al2Ca particles intergran

In order to investigate a protective coating approach for nuclear applications, two different aluminum rich layers were deposited on T91 steel coupons: Ti-Al-N films were grown via High Power Impulse Magnetron Sputtering and Al O coatings were produc

This work presents a new experimental process for the thermal treatment of prosthetic coatings obtained by electrodeposition on titanium alloy Ti6Al4V. This thermal treatment is required to evaporate the solvent from the coating and to improve its co
