一、光亮淬火概述采用某些在高温下容易裂化的有机液体,热裂成H_2、CO和CH_4等具有还原和弱渗碳能力的气氛,使之通入工件加热的炉膛内和炉膛至冷却剂液面的全部空间通道,使工件从加热到冷却的全过程中,始终置于控制气氛的保护下。由于工件不受大气的氧化,淬火后的工件表面具有光亮(银灰色)的特点。可以热裂成控制气氛的有机液体有:甲醇(CH_3OH)、乙醇(C_2H_5OH)、丙酮(CH_3COCH_3)、醋酸乙酯(CH_3COOC_2H_5)等。上述这些有机液体裂化后过剩的碳不多,不象
First, the bright quenching Overview Some of the easily cracked organic liquids at high temperatures, hot cracking H_2, CO and CH_4 and other reduction and weak carburizing ability of the atmosphere, so that the workpiece is heated to open the furnace and the furnace to the coolant The entire surface of the liquid channel, the workpiece from heating to cooling the entire process, always placed under the control of the atmosphere. As the workpiece is not the oxidation of the atmosphere, after quenching the surface of the workpiece has a bright (silver) characteristics. Organic liquids that can be thermally cracked into a controlled atmosphere include methanol (CH 3 OH), ethanol (C 2 H 5 OH), acetone (CH 3 COCH 3) and ethyl acetate (CH 3 COOC 2 H 5). Above these organic liquid after cracking excess carbon is small, not like
