Effect of nitrogen content on the structure and properties of nitrocarburized steel

The Increase of Mechanical Properties at Nitrocarburizing with High Nitrogen Content

“…Проведенные исследования показыва-ют, что кинетика роста нитроцементован-ных слоев с повышенным содержанием азо-та достаточно сложна и многообразна, за-висит от уровня азота и углерода, типа ле-гирования, температуры закалки, времени химико-термической обработки [12][13][14]. При пересыщении стали азотом кинетика характеризуется, видимо, гомогенным рас-слоением твердого раствора наряду с ге-терогенным зарождением специальных нит-ридов, обладающих малой склонностью к росту и коагуляции.…”

Structural, Morphological and Optical Properties of Nanoproducts of Zirconium Under Laser Ablation in Water and in Aqueous SDS Solutions

“…[55], that leads to cavities formation inside particles due to differences of component diffusion rate. The formation time may make up to several minutes [51] and it goes down noticeably when particles are heated. In this regard, the appearance of such particles in the experiments is highly probable.…”

Surface-Modified Magnetic Nanoparticles for Cell Labeling

“…As a hydrophilic ligand, mPEG was selected due to its non-toxicity, hydrophilicity and low opsonization in biological media. mPEG was terminated with groups, such as phosphonic (PO(OH) 2 ) [29] and hydroxamic (NHOH) acid [30], exhibiting strong interactions with the iron ions. Fe 3 O 4 particles prepared by thermal decomposition were coated by mPEG terminated with phosphonic (PAmPEG) or hydroxamic acid (HA-mPEG).…”
