Oxygen, nitrogen and carbon are related to the powder surface, debinding, sintering atmosphere, phase composition and final performance, and should be evaluated according to the specific grade, process and specifications of both parties.
Engineering focus: Oxygen, nitrogen and carbon analysis
Review the material, particle-size, process and validation factors that matter for this application.
The data of different objects have different meanings.
The anomalies cannot be attributed solely to the original powder.
Chemical data is required to connect part results.
Oxygen content and powder state
Atomization route, particle surface area, storage and handling may affect powder surface condition. When comparing fine powders, oxygen content needs to be understood along with particle size and morphology.
Carbon content and MIM process
The raw powder, binder, and debinding sintering process can all affect the final carbon state. Oversimplification to a single powder indicator easily overlooks the source of the process.
Reports must be associated with objects
Procurement requirements should indicate whether powder, debound blanks or sintered parts are tested, and the method, batch and heat treatment status should be recorded to avoid direct comparison of data from different objects.
Discuss your powder project
Share the process step, operating conditions and part result you want to improve.
- Target grade, batch or order information
- Particle size, density, flow or composition items of concern
- Customer inspection methods and receiving requirements
- Packaging, labelling, delivery and traceability needs
