titanium pump coating or surface treatment methods

Titanium tube developed for use under low temperature
   Have developed a new titanium pumps alloy tube may be at a higher temperature to make an application of the tube
compared with the low temperature high-strength titanium alloys have been developed which improve the
efficiency and saving of metal and having a side greater potential, future goal is to develop a
temperature can reach 650 ℃ titanium tube, this alloy can be used for high-pressure turbine wheel,
and the wheel base compared to the commonly used reduce weight by 20%.
     But with the increase of the operating temperature is bound to bring more new problems, such as
surface oxidation, producing titanium alloy pump large quantities of long-term stability of metallurgy, friction and
corrosion, fire danger and hot salt stress corrosion. Some problems can be solved with a surface
coating or surface treatment methods, for which is currently being actively conducted research in this area.
