Titanium powder production apparatus and method
View Patent ↗A method and apparatus for producing titanium metal powder from a melt. The apparatus includes an atomization chamber having an inner wall that is coated with or formed entirely of CP-Ti to prevent contamination of titanium metal powder therein. The inner surfaces of all components of the apparatus in a flow path following the atomization chamber may also be coated with or formed entirely of CP-Ti.
1. Apparatus for producing titanium metal powder from a melt including titanium powder metal, comprising an atomization chamber having an inner wall that is coated with or formed entirely of commercially pure titanium to prevent contamination of titanium metal powder therein, further comprising a powder conveying tube connected to an exit opening of the atomization chamber, a cyclone separator connected to the powder conveying tube and a powder container connected to the cyclone separator, and wherein inner surfaces of the conveying tube, the cyclone separator and the powder container are coated with or formed entirely of commercially pure titanium.
2. A method for preventing contamination of titanium powder in an apparatus for producing it from a melt including titanium powder metal, the apparatus having an atomization chamber with an inner wall, comprising coating the inner wall or forming it entirely of commercially pure titanium, wherein the apparatus further comprises a conveying tube, a cyclone separator and a powder container in a flow path following the atomization chamber, and coating inner surfaces of the conveying tube, the cyclone separator and the powder container with commercially pure titanium or forming the inner surfaces thereof entirely of commercially pure titanium.
3. A method for preventing contamination of titanium powder in an apparatus for producing it from a melt including titanium powder metal, the apparatus having an atomization chamber with an inner wall, comprising coating the inner wall or forming it entirely of commercially pure titanium, and further comprising coating inner surfaces of all components of the apparatus in a flow path following the atomization chamber with commercially pure titanium or forming the inner surfaces entirely of commercially pure titanium.
4. Apparatus for producing titanium metal powder from a melt including titanium powder metal, comprising an atomization chamber having an inner wall that is coated with commercially pure titanium to prevent contamination of titanium metal powder therein, wherein the inner wall is formed of stainless steel.
5. A method for preventing contamination of titanium powder in an apparatus for producing it from a melt including titanium powder metal, the apparatus having an atomization chamber with an inner wall, comprising coating the inner wall with commercially pure titanium, wherein the inner wall is formed of stainless steel.
