X-ray photoelectron spectroscopy was applied to study the composition of the passive film formed on an extremely corrosion resistant amorphous Fe-10at.%Cr-13at.%P-7at.%C alloy in 1 N HCl. The passive film consists mainly of hydrated chromium oxyhydroxide which is a common major constituent of passive films on crystalline stainless steels. The extremely high corrosion resistance of the amorphous alloy can only in part be attributed to the formation of a protective hydrated chromium oxyhydroxide film.

Synthesis, characterization, and CO2 capture study of micro-nano carbonaceous composites.

Cotton gin trash (CGT) was used to produce activated carbon via pyrolysis and steam activation. To determine the effect of pyrolysis temperature and time on the properties of activated carbon, optimization of the pyrolysis conditions at temperatures of 600, 700, and 8000C for 30, 45 and 60 minutes were made. Steam activation of the product char was prepared at temperatures range of 250-600oC and ambient pressure (14.7 psi) for 60 minutes while iodine number and ash analysis were conducted to evaluate the adsorption capacity of the produced activated carbon. Char production was found to decrease with increasing pyrolysis temperature and time. Whereas, the optimal increase in iodine number value from 200 to 427 was observed at 7000C and 45 minutes pyrolysis conditions. Using the concept of biomass iodine number, the adsorption property of the CGT activated carbon was found comparable with commercially available activated carbon from lignite, which had an iodine value of 600.

Type IP-2 machine for short-endurance fatigue tests on metals in liquid media

The effect of polarization on stress-corrosion cracking of carbon steel in various media was studied. It was established that the character of the polarization curves depends on the structural state of the metal and on the nature of the corrosive medium.
