Abstract

В заявке описан способ изготовления из металлического порошка деталей окончательной или близкой к окончательной формы, при осуществлении которого изготавливают вкладыш точных размеров, соответствующих размерам отверстия, растачиваемого в готовом статоре, при этом отверстие имеет длину по меньшей мере 750 мм, устанавливают вкладыш в полости литейной формы, заполняют полость литейной формы металлическим порошком, подвергают порошок изостатическому прессованию и затем извлекают материал вкладыша. Форма может представлять собой отдельную форму, которую удаляют после начальной стадии с целью связывания порошка и получения заготовки, которую затем заключают в соответствующую оболочку, такую как контейнер или наносимое методом распыления покрытие. Вкладышем может являться металлический вкладыш из материала, такого как медь, который впоследствии может быть удален путем химического травления. Вкладыш может быть покрыт материалом, поддающимся удалению путем травления для облегчения извлечения вкладыша. Металлический вкладыш может быть покрыт материалом, который обеспечивает диффузионный барьер, препятствующий атомарной диффузии материала вкладыша в порошок, уплотняемый в процессе ГИП.The application describes a method for manufacturing parts of a final or close to final shape from a metal powder, in the implementation of which an insert is made of exact dimensions corresponding to the dimensions of the hole bored in the finished stator, while the hole has a length of at least 750 mm, the insert is installed in the cavity of the casting mold , filling the mold cavity with metal powder, subjecting the powder to isostatic pressing, and then removing the liner material. The mold can be a separate mold that is removed after the initial step to bond the powder and form a preform, which is then enclosed in an appropriate shell, such as a container or spray coating. The liner can be a metal liner of a material such as copper, which can subsequently be removed by chemical etching. The liner may be coated with a removable etch material to facilitate removal of the liner. The metal liner can be coated with a material that provides a diffusion barrier that prevents atomic diffusion of the liner material into the powder that is compacted in the HIP process.
