采用X-Y函数记录仪（LM20A-200型），测定30#机油及油基-碳纳米管（CNTs）纳米流体淬火液冷却特性曲线。研究CNT含量的变化对油基-CNT纳米流体淬火液冷却特性曲线及45#钢硬度的影响。结果表明：随着CNTs含量的增加，纳米流体的冷却能力逐渐增大；采用质量分数为1.5%的油基-碳纳米管纳米流体淬火液和30#机油分别对45#钢进行淬火处理，经油基-碳纳米管纳米流体淬火液淬火后45#钢的硬度有所提高。
Cooling curves of oil based-carbon nanotube(CNTs)nanofluids quenchant and 30# oil were measured by using X-Y function recorder. The effect of Carbon Nanotube (CNT) concentration on the cooling characteristic curves and mechanical properties of 45# steel was studied during immersion quenching in oil based-CNT nanofluids. The results show that the cooling power of nanofluids increases with the increase of CNTs concentration. The 45# steel samples were quenched by mass fraction 1.5% oil based-carbon nanotube(CNT)nanofluids quenchant and 30# oil. The results show that mechanical properties of 45# steel with oil based-carbon nanotube nanofluids quenchant is better than that with 30# oil.
