“…These improve the tribological properties of steel. However, the presence of nitrogen and tungsten phases can be explained by the greater improvement of tribological properties occurring for nitrogen than for pulse plasma treatment [6][7][8]. Figure 5a and b shows the wear tracks of the sample 1 and sample 2.…”

“…Their concentration under the experimental conditions reached 50 at % [11]. The coating with a thickness up to 300 nm was clusters formed in the region close to the target and later con densed on its surface, which indicates the quite intense process of ablation of the target.…”

“…Earlier studies on depositing products of the explo sion of a conductor or dispersed metal powder using compression plasma flows generated by a quasi sta tionary plasma accelerator showed that atoms of the substrate material are present in the formed nano structured coating [10,11]. Their concentration under the experimental conditions reached 50 at % [11].…”

“…Существенное отли-чие состоит в том, что вклад в формирующуюся микроструктуру приповерхностных слоев мише-ни может вносить насыщение плазмообразующим газом, ведущее к формированию новых дис-персных фаз. В работе [64] в сформированную струю плазмы с плазмообразующим газом -азо-том -подсыпался порошок вольфрама, что приводило к формированию на поверхности стальной мишени вольфрам-содержащего слоя, с максимальной массовой долей доходящей до 20 %. Дос-таточно в высокой концентрации в приповерхностном слое обнаруживались азот -20 % и угле-род -10 %, который, по-видимому, присутствовал в камере как остаточная атмосфера.…”
