Example Embodiment
[0047]Example 1:
[0048]The part 3 of the present embodiment requires a tooth portion 31, a spline 33 and an outer runway carbon depth of 1.10-1.30 mm, and the carbon surface hardness is 60-63 hrc, and the amount of deformation of the carburizing surface is ≤0.2.
[0049](1) Part 3 has completed the carbon noodles before carburizing (figure 2 The processing of X1, X2, X3), and the remaining surface copper plated protective carbon precipitating parts 3 structure.
[0050](2) Part 3 is placed in a blowing machine to clean the carburized surface (figure 2 The number of X1, X2, X3), the number of crusts of the corundum is 100 mesh, the wind pressure ≤0.10 MPa (this embodiment is 0.1 MPa), ensuring the blown carbon noodles after the blow.
[0051](3) Part 3 is placed in a controlled atmosphere to perform a controlled atmosphere to carburize: the part 3 uses a carbonaceous furnace tool to take 11 flat stability furnace; the spacing between the parts 3 is 35mm (in other embodiments, the spacing ≥ 15m...
