Рис. 1. Кинетика изнашивания плазменных покрытий, полученных напылением с оплавлением порошков: 1 - ПГ-10Н-01; 2, 3, 4 и 5 - ПГ-10Н-01 с добавлением нанопорошка Al2O3 в количестве 0,2, 1, 1,5 и 5об.% соответственно.

Из анализа графиков приведенных на рис. 1 можно сделать вывод, что наибольшую износостойкость имеет покрытие на основе порошка ПГ-10Н-01 с добавлением нанопорошка Al2O3 в количестве 1,5об.% (кривая 4). Увеличение нанопорошка до 5 об.% приводит к ухудшению износостойкости (кривая 5). Наличие наночастиц оксида алюминия в покрытии в количестве 1,5%, как показали испытания, также способствует снижению коэффициента трения на 38%. Дальнейшее увеличение концентрации нанооксидов на уменьшение коэффициента трения существенно не влияет.

Выводы
Установлено, что применение нанопорошков оксидов Al2O3 и TiО2 эффективен для управления структурой и механическими свойствами как сварных швов, так и напыленных покрытий.
Повышение механических свойств присуще всем исследовательским образцам, при этом наиболее существенное влияние оказывает нанооксид алюминия в количестве 0,5об.%, увеличивая предел текучести сварного шва на 49% и предел прочности на 23%. Увеличению ударной вязкости сварных швов, примерно в 2 раза, наиболее способствует оксид титана в количестве 1об.%.
Введении нанопорошка оксида алюминия в количестве 1,5об.%. в плазменные покрытия позволило уменьшить коэффициент трения и увеличить износостойкость покрытий в 2-3 раза.
