Process Control
The vacuum environment allows for precise control over carbon content, reducing impurities on the surface of hard phases and improving the wetting behavior between the binder phase and hard phases, resulting in higher alloy strength, particularly in TiC-containing alloys. The process simplifies operations by integrating dewaxing-sintering, reducing oxidation and carbon control difficulties. Its design minimizes equipment footprint and reduces manual labor intensity.
The vacuum heat treatment furnace supports multi-atmosphere dewaxing-sintering with precise control over temperature, atmosphere, and furnace pressure across various temperature stages, achieving isothermal sintering at any temperature. It is also capable of specialized processes like gradient alloy sintering.
