2
In order to improve the accuracy of small-module gears
small-module gears are prepared by using 420 stainless steel powder as raw material and metal powder injection molding (MIM) process at a sintering temperature of 1 330-1 360 ℃. The injection blank with the best micro-morphology was taken as a prerequisite to study the effect of sintering temperature on the accuracy of small-module gears.
Methods
2
MLA650F field emission scanning electron microscope was used to observe the microscopic morphology of the gear injection blanks; JE 20 gear measuring center
Image J software
and Rockwell hardness tester were used to measure the accuracy
porosity
and hardness of the sintered gears
respectively.
