Исследованные покрытия были получены из растворов с глицином в качестве основного лиганда и содержали 10,2…15,6 ат.% фосфора и до 3,3 ат.% вольфрама. Показано, что покрытия Ni-W-P с содержанием вольфрама 2,3…3,3 ат.% толщиной 15 мкм имеют существенно более низкую пористость по сравнению с никель-фосфорными покрытиями той же толщины. Также установлена заметно лучшая стойкость покрытий Ni-W-P в атмосфере соляного тумана, степень коррозионного поражения которых меньше, чем у покрытий Ni-P, и относительно мало зависит от продолжительности выдержки в коррозионно-активной среде. Анализ анодных поляризационных кривых показал практически одинаковую электрохимическую активность при растворении в серной кислоте покрытий Ni-P и Ni-W-P. Оба данных типа химико-каталитических покрытий показали заметно лучшую склонность к анодному растворению, чем чистый никель. С учетом полученных экспериментальных данных сделан вывод о более высоких защитных характеристиках покрытий Ni-W-P по сравнению с никель-фосфорными покрытиями. Основной причиной худших защитных свойств покрытий Ni-P является их относительно высокая пористость</p></abstract><trans-abstract xml:lang="en"><p>Corrosion resistance properties, such as porosity, stability in the atmosphere of NaCl mist, and anodic electrochemical activity in a sulfuric acid solution are studied and compared for Ni-W-P and Ni-P coatings obtained by electroless deposition. The studied coatings were obtained from solutions with glycine as the main ligand and contained 10.2 to 15.6 at.% of phosphorus and up to 3.3 at.% of tungsten. It is shown that Ni-W-P coatings with a tungsten content of 2.3 to 3.3 at.% and a thickness of 15 μm have a significantly lower porosity as compared with nickel-phosphorus coatings of the same thickness. Also, significantly better stability of Ni-W-P coatings in a NaCl mist atmosphere was observed, their corrosion damage degree is less than that of Ni-P coatings, and relatively little depends on the duration of exposure in a corrosive environment. Analysis of anodic polarization curves showed an almost similar electrochemical activity upon dissolution of Ni-P and Ni-W-P coatings in sulfuric acid. Both these types of electroless coatings showed a markedly better tendency to anodic dissolution than pure nickel. Taking into account the obtained experimental data, a conclusion is made as to the better protective characteristics of Ni-W-P coatings in comparison with nickel-phosphorus coatings. The main reason of the inferior protective properties of Ni-P coatings is their relatively high porosity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коррозионно-защитные свойства</kwd><kwd>химико-каталитические покрытия</kwd><kwd>Ni-P</kwd><kwd>Ni-W-P</kwd></kwd-group><kwd-group xml:lang="en"><kwd>corrosion resistance properties</kwd><kwd>electroless coatings</kwd><kwd>Ni-P</kwd><kwd>Ni-W-P.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hamdy A.S., Shoeib M.A., Hady H., Abdel Salam O.F.
