Heat treatment of automotive gear materials

The heat treatment strengthening technology of automobile gears should pay attention to the control of surface integrity, that is, to control the microstructure, depth, core hardness, residual stress and so on. Improper heat treatment control of automobile gears can easily lead to excessive grain boundary oxide layer structure, decarburization,...
