The advantages of vacuum sintering include:
1. Lack of oxidation and atmosphere contamination: Vacuum sintering reduces the contamination of harmful substances such as water, oxygen, nitrogen, and other impurities in the atmosphere. This helps to avoid adverse reactions such as decarburization, carburization, reduction, oxidation, and nitriding. The vacuum environment provides a clean and controlled atmosphere for sintering.
2. Improved material properties: Vacuum sintering removes the oxide film before the liquid phase appears, which improves the wettability of the liquid and carbide phases. This leads to an improved microstructure of the alloy and enhanced properties such as wear resistance and strength. Additionally, the reduction of gas within the pores of the material increases the density of the material.
3. Precise process control: Vacuum sintering allows for precise setting and monitoring of the process parameters. This enables better control over the sintering conditions and ensures consistent and high-quality results. Vacuum sintering furnaces provide easy maintenance and maximum productivity.
4. Superior quality and flexibility: Vacuum sintering produces bright, clean parts with no seams, joints, or fillers. It is particularly beneficial for small or complex parts that are difficult to produce by casting or machining. Vacuum sintering also offers incredible design flexibility and quick turnaround time.
5. Essential for 3D metal printing: 3D metal printing often requires vacuum sintering as a finishing step to achieve the necessary hardness, size, and density of the printed components. Without vacuum sintering, the components may be faulty or require extensive mechanical finishing.
In summary, vacuum sintering offers advantages such as improved material properties, precise process control, superior quality, flexibility, and its necessity in certain manufacturing processes like 3D metal printing.
