近年来钢的光亮淬火法得到了广泛的应用。光亮淬火时零件是在中性气氛或盐槽中加热,而在不溶解氧的盐浮中冷却,用这种方法淬火,零件的表面虽则光亮但不光洁。如果在淬火后即获得光洁的表面是很有益的,因为如此就可省去以后的磨光和抛光工序。光洁淬火后的零件可以直接进行电镀(镀镍、铬等)。此外,按光洁淬火 In recent years, the bright steel quenching method has been widely used. Bright quenching parts are heated in a neutral atmosphere or salt tank, and not dissolved in the salt float in the cooling, quenching in this way, although the surface of the part is bright but not clean. It is helpful if a smooth surface is obtained after quenching because this eliminates the need for subsequent polishing and polishing operations. Bright quenching parts can be directly plated (nickel, chromium, etc.). In addition, according to bright and clean quenching
