Нанесение покрытий методом ионно-вакуумного напыления

ООО «НПП Булат» — инновационное предприятие, которое ведет разработки и исследования в области производственных процессов ионного азотирования, вакуумного и плазменного осаждения износостойких и функциональных покрытий применительно к машиностроению и медицине.

Предприятие разработало принципиально новый технологический процесс вакуумно-плазменного нанесения покрытий с ассистированием пучком высокоэнергетических ионов металлов. Сущность технологии — вакуумное нанесение покрытий из плазмы с одновременным облучением пучком высокоэнергетических ионов металлов.

Осаждение покрытий с одновременным облучением его высокоэнергетическими ионами дает значительный положительный эффект, который достигается воздействием пучка при подготовке поверхности перед нанесением, активацией процессов, ответственных за формирование покрытия, а также непрерывным воздействием пучка на всю систему «покрытие-подложка».

ионно-вакуумное напыление

Положительные эффекты заключаются в следующем:

  • покрытия приобретают высокую адгезию при низкой (ниже 100°С) температуре, что исключает поверхностное оплавление, отпуск и коробление. Это особенно важно при нанесении покрытий на образцы с низкими температурами плавления или отпуска;
  • улучшается микроструктура покрытий, увеличивается плотность и однородность покрытий, размельчается столбчатая структура; вероятно формирование мелко- и супермелкодисперсной структуры разориентированного кристалла, которая наиболее адаптирована к сопротивлению микроразрушению в условиях повышенных термомеханических напряжений и имеет лучшие показатели по сопротивляемости изнашиванию в указанных условиях. Увеличивается износо-, усталостная и эрозионная стойкость изделий с покрытиями;
  • исчезает сквозная пористость, что увеличивает прочность и улучшает коррозионную стойкость покрытий. Это важно для деталей авиационных двигателей и энергетических установок;
  • появляется возможность непрерывного легирования растущего покрытия на всю его толщину, что позволяет создавать новые поверхностные сплавы, в т. ч. не реализуемые в равновесных условиях и обладающие уникальными упрочняющими свойствами.

Разработки реализуются в самых разных сферах промышленности — металлургической, машиностроительной, энергетической, газовой, нефтехимической, медицинской, кондитерской и др.

ионно-вакуумное напыление

Предприятие предлагает:

  • износостойкие нитрид-титановые (ТIN) покрытия на дисковые пилы с твердосплавными зубьями. Обеспечивают увеличение ресурса до 30% с возможностью многократного перенапыления после перезаточки;
  • защитно-упрочняющие и декоративные покрытия различного технологического назначения (TiN, ZrN, TiAIN, TiNC);
  • разработку, проектирование и сборку установок плазменного и микроплазменного напыления и наплавки порошковыми материалами для нанесения упрочняющих и защитных покрытий на детали и изделия подвергающихся износу;
  • ремонт, восстановление и модернизацию вакуумного, газотермического и сварочного оборудования. Настройку, техническое обслуживание и технологическое сопровождение при выполнении производственных задач;
  • разработку технологии нанесения износостойких, композиционных, многослойных покрытий на твердосплавные фрезы для обработки изделий из титановых сплавов и тугоплавких материалов.
