Quality Control of Heat-Treated Surface of 20CrMo Steel Transmission Countershaft

Abstract:

Article Preview

After heat treatment, the surface hardness and effective depth of hardened layers of automotive transmission countershaft, determines the quality of the part itself as well as the normal and reliable operation of the transmission assembly. The paper analyzes the specific reasons for such problems as soft zone on the hardened surface of transmission countershaft when proceeding with carbonitriding in the controlled atmosphere furnace, a multi-purpose furnace. And with process parameters adjusted, the process parameters of heat treatment are corrected that the soft zone has been eliminated and the quality of parts has been effectively controlled.
