Данные табл. 1 свидетельствуют о росте как предела текучести, так и предела прочности при введении в сварочную ванну нанооксидов титана и алюминия. Наиболее существенное влияние на эти показатели оказывает нанооксиды алюминия, увеличивая предел текучести на 178МПа (49%) и предел прочности 126МПа (23%). На ударную вязкость наиболее влияет оксид титана, повышая ее значение примерно в 2 раза. Как отмечалось выше, эффективным для повышения эксплуатационных свойств газотермических покрытий является также применение нанопорошков. Присутствие наночастиц в исходном порошковом материале способствует увеличению поверхностной энергии, что положительно отражается на стадиях формирования покрытий, следствием чего является повышение их эксплуатационных свойств, несмотря на то, что доля наночастиц в покрытии составляет несколько процентов. При плазменном напылении износостойких покрытий, как и при сварке использовали нанопорошок Al2O3. Как матрицу применяли самофлюсующий порошок ПГ-10Н-01 фракцией 40-63 мкм, который широко применяется для нанесения износостойких покрытий газотермическим напылением с дополнительным оплавлением. Приготовления гомогенной порошковой смеси с макро- и наночастиц осуществляли с помощью также механохимической обработки в планетарном шаровой мельнице с дополнительным вакуумированием рабочих емкостей. Наночастицы оксида алюминия в условиях вакуума и механохимической обработки переходят в активированное состояние и присоединяются к частицам других элементов, образуя физические связи между компонентами покрытия. При плазменного напыления порошковой смеси покрытия формируются из продуктов реакции компонентов, которые взаимодействуют, как во время движения частиц, так и на поверхности основания. Покрытие напыляли специальным плазмотроном с частично вынесенной дугой. Благодаря конструкционным особенностям плазмотрона и режимам, достигали формирования плазменной струи по характеру течения близким к ламинарному. Удлиненный высокотемпературный участок плазменной струи с дополнительной газовой защитой обеспечивает лучшие условия для переноса наночастиц в напыленные покрытия. Как плазмообразующий и защитный газ использовали аргон. Рабочий ток устанавливался в пределах 80-100 А, напряжение 50-60 В, расход газа 2-3 л / мин при диаметре сопла 2 мм. После напыления покрытия оплавляли в муфельной печи при температуре 1050ºС течение 5 мин. Покрытие наносили на плоские образцы с размером 5 × 10 × 20 мм из стали 3. Толщина покрытий составляла в пределах 0,3-0,5 мм. Полученные покрытия исследовали на кинетику износа в условие сухого трения при возвратно-поступательном движении плоского контртела из закаленной стали с нагрузкой 3 кг. Результаты испытаний представлены на рис.1.
