Abstract: This paper analyzes the various influencing factors of gear heat treatment deformation, and points out that the heat treatment deformation of gear parts is mainly affected by many factors
In a unified way Φ 50 4140 mm x 300 mm steel bending fatigue test specimens. The samples were austenitized at 860℃ in a protective atmosphere, and then conventional quenching
For the quenching of a single workpiece, the spray quenching technology itself can achieve controllable pre-cooling quenching, because it can be preset for the beginning of the spray. For batch
In order to achieve reverse quenching, steel with appropriate hardenability, a workpiece with sufficient cross-section, suitable cooling medium, and correct cooling conditions are required. If these conditions are met, this
1. Hardening crack Hardening crack is the most common defect of high frequency induction hardening. There are many causes, such as overheat, too fast cooling speed, and improper microstructure before
