Working with CP-Ti Powder (GB/T 30265)-PS
Is CP-Ti Powder (GB/T 30265) easy to machine?
Machine consolidated PM parts with sharp uncoated carbide, low speed (30–60 m/min), heavy rigid setup and flood coolant; titanium chips and grinding dust ignite easily.
Can CP-Ti Powder (GB/T 30265) be welded?
GTAW/EBW/LBW with full argon or vacuum shielding gives sound joints, but porous as-sintered parts outgas — weld only HIP'd or >99 % dense material.
Can CP-Ti Powder (GB/T 30265) be formed, bent or molded?
Cold-press at 400–700 MPa with lubricated die (HDH powder), vacuum sinter 1200–1300 °C; spherical GA/PREP powder is used for HIP, MIM and laser/electron-beam AM under inert atmosphere.
What surface finishes work on CP-Ti Powder (GB/T 30265)?
Shot-peen or chemically mill AM surfaces, then colour anodise, plasma-spray HA or passivate; avoid chlorinated cleaners and never anodise parts with open interconnected porosity.
