Method for Producing a Component with Defined Porosity and Component

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for producing components with defined porosity using cold gas spraying. With this approach, a porous region is established on a component by depositing material (such as metal or a metal-ceramic mixture) in a controlled manner. The process enables precise adjustment of the porosity, which is essential for applications like reference leaks (for calibrating leak detectors) and separation processes (as filtration membranes). The technique allows defined gas or fluid permeability in the produced parts with minimal technical effort and high reproducibility.

Use CasesContent extracted from patent full text and abstract with AI.

• Production of reference leaks (calibrated leaks) for checking and calibrating leak detectors used in quality assurance, maintenance, or industrial systems.
• Manufacturing of membranes or filters for particle separation, gas separation, or liquid filtration in chemical, pharmaceutical, or environmental processes.
• Creation of components requiring defined gas or liquid permeability, such as in sensor housings, venting devices, and controlled leak sources for scientific testing.
• Custom manufacturing of porous metal or metal-ceramic structures for research, industrial, or educational demonstration purposes.
• Fabrication of components with localized porosity to serve as test samples for nondestructive testing methods.

BenefitsContent extracted from patent full text and abstract with AI.

• Highly controlled and reproducible porosity, enabling precise adjustment of the component’s permeability.
• Low technical complexity compared to alternative methods, making manufacturing more cost-effective and scalable.
• Stable long-term performance, as the created porosity and permeability remain unchanged over time, even under typical storage and use conditions.
• Ability to use a wide range of metals (e.g., nickel, stainless steel, titanium) and ceramics, offering flexibility for different environments and uses.
• Reduced heat input in the process, allowing use with heat-sensitive materials, and avoids damaging or altering the substrate.
• Capability to manufacture both fully and partially porous components, or to close openings precisely with a porous layer for calibration or filtration purposes.

Patent Abstract

The invention relates to a method for producing a component that is at least partially porous, a component, and a use of a component. In the method for producing a component (10) that is at least partially porous, at least one porous first region (11) of a component (10) is produced by cold gas spraying. In this way, a defined porosity can be set with particularly low technical effort.
