电子束表面淬火工艺的热源是一束从电子枪射出的高能电子,该电子枪与电子束焊机的电子枪相同,由高速微型计算机控制。电子束逐点跟踪光栅格子在几微秒时间内传递每一点所需要的能量。热处理在50～100μm压力下进行,不需要扩散泵。真空室保持部件清洁,部件是自淬的,自淬有许多优点,包括淬火速度快。钢的 The heat source of the electron beam surface hardening process is a bunch of high-energy electrons emitted from an electron gun that is controlled by a high-speed microcomputer like the electron gun of an electron beam welding machine. The electron beam traverses the grating grid one by one to deliver the energy required for each point in a few microseconds. Heat treatment at 50 ~ 100μm pressure, no need for diffusion pump. Vacuum chamber to keep the parts clean, the parts are self-quenching, self-quenching has many advantages, including quenching speed. Steel
