Application of Vacuum Sintering Furnaces for Titanium Plates
Titanium plates are primarily used in fields with extremely high demands on material properties, such as biomedicine, aerospace, chemical engineering, and energy sectors. They leverage the excellent biocompatibility, superior corrosion resistance, high strength, and lightweight characteristics of titanium and its alloys.
The vacuum sintering process effectively controls material purity, porosity, and microstructure, proving particularly crucial for preparing porous titanium coatings. It ensures high-temperature treatment occurs in an oxygen-free or inert gas environment, yielding titanium plates or coatings with superior performance.
The vacuum sintering process for titanium plates follows these steps:
Temperature: Ambient ~ Max 1,050°C,2-3 stage ramp-up (1-2 hours dwell time per stage);
Cooling:Natural cooling (furnace cooling) after reaching or maintaining peak temperature
Ramp rate: 3°C/min
Vacuum: 5×10⁻⁵ Torr maintained (until furnace cooling)
