Abstract

В заявке описан способ изготовления изделия заданной или близкой к заданной формы путем горячего изостатического прессования или горячего одноосного прессования, в котором используют содержащий нитрид бора диффузионный фильтр, расположенный между графитовым шаблоном и прессуемым с его помощью металлическим порошком. Диффузионный фильтр позволяет диффундировать регулируемому количеству углерода через поверхность прессованного компонента. Нитрид бора обычно наносят в виде водной суспензии или путем распыления. Для обеспечения сцепления между покрытием и поверхностями шаблона на поверхность графитового шаблона наносят один или несколько тонких фантомных слоев суспензии до нанесения одного или нескольких слоев суспензии нормальной прочности. Каждому слою покрытия дают высохнуть до нанесения следующего слоя, при этом шаблон может быть нагрет с целью сушки каждого слоя. Могут обрабатываться прессованные компоненты длиной более 2 м, при этом относительную усадку компонентов и шаблона во время охлаждения адаптируют путем нанесения на шаблон покрытия из нитрида бора. Путем испытаний может быть определена толщина покрытия для достижения управляемой диффузии углерода через поверхность прессованного компонента и выбраны размеры шаблона для адаптации к этой толщине покрытия.The application describes a method of manufacturing a product of a given or close to a given shape by hot isostatic pressing or hot uniaxial pressing, which uses a diffusion filter containing boron nitride located between a graphite template and a metal powder pressed with it. The diffusion filter allows a controlled amount of carbon to diffuse through the surface of the pressed component. Boron nitride is usually applied as an aqueous suspension or by spraying. To ensure adhesion between the coating and the surfaces of the template, one or more thin phantom layers of the slurry are applied to the surface of the graphite template prior to the application of one or more layers of the slurry of normal strength. Each layer of coating is allowed to dry prior to application of the next layer, while the template may be heated to dry each layer. Pressed components longer than 2 m can be machined, with the relative shrinkage of the components and of the template during cooling adapted by applying a boron nitride coating to the template. Testing can determine the thickness of the coating to achieve controlled diffusion of carbon through the surface of the molded component and size the template to adapt to this coating thickness.
