Neodymium salt was used as additives in preparing anodic aluminum oxide (AAO) films to improve its performance. AAO films were prepared by anodization method from a 15 vol. % sulphuric acid solution containing neodymium salt. The effects of anodization voltage, anodization temperature and anodization time on microhardness and thickness of AAO films were researched, respectively. The thickness of AAO film increases with the increase of anodization voltage, the microhardness of AAO film decreases with the increase of anodization voltage in 19 V～23 V. The thickness of AAO film increases with the

The effect of addition of ZrO2 and CeO2 nanoparticles, average current density, duty cycle and pulse current on microhardness of Ni-ZrO2-CeO2 nanocomposites were studied. The results show that microhardness of nanocomposite is increased at first and then decreased with the increasing additive amounts of two kinds of nanoparticles. With increasing reverse the average current density, the microhardness of the composite coating increases. Also, the microhardness of nanocomposite fall with the increasing of pulse frequency

In the present work, three heats of Si-Mo-Cr ductile cast iron with varying amounts of major alloying elements are produced. The effect of the microstructural features on the microhardness, tensile strength and ductility is studied. Increasing the nodule count decreases the pearlite-ferrite ratio, which results in a decrease in tensile strength but an increase in percentage elongation. The spherical nodule plays a significant role in arresting the crack and reorients the crack path around the nodule, as evident from the results of scanning electron microscopy.

Abstract The thermal aging and consequent embrittlement of materials are ongoing issues in cast and duplex stainless steel.

This process is also operative in welds in either cast or wrought stainless steels where delta ferrite is present. While the embrittlement can occur after several hundred hours of aging at 475°C, it can also occur at lower temperatures where ductility reductions have been observed after several tens of thou

A method and experiments of nitriding AISI 1020 steel with simultaneous heating of the samples with the electron component of plasma are described. A nitriding regime is explained that makes it possible to form a hardened layer up to 500 µm thick. It is shown that the microhardness of the surface layer of the steel increases with the increase in the nitriding temperature and correlates with the relative content of the nitride phase. It has found that in the nitriding temperature range from 450 °C to 600 °C, the maximum microhardness is formed in the near-surface layer at the depth of ~10 µm at
