Reusability Analysis of Metal Powder
Reusability analysis of metal powder checks the physical and chemical changes of the powder after multiple build cycles to determine the maximum number of cycles.
Physical-Chemical Mechanism of Action
Reusability analysis examines how metal powder behaves under repeated use. Properties such as particle size, chemical composition, and mechanical strength are checked.
Metallurgical Relevance & Welding Risks
Excessive reuse can cause powder coarsening, which impairs toughness and microstructure. This increases susceptibility to cracking and reduces component lifespan.
Workshop Practice & Action Items
For accurate analysis, perform the following steps:
1. Powder handling: Clean and inspect the powder before each use.
2. Build cycles: Set the maximum number of build cycles to 5 to 10, depending on the specific application.
3. Chemical analysis: After each cycle, verify the powder's chemical composition and reprocess if necessary.
