摘要: 对27CrMnB履带钢进行不同温度淬火+200 ℃回火处理,研究了不同淬火温度条件下27CrMnB钢的力学性能,从磨痕深度、磨痕宽度、磨损体积和摩擦因数等方面对试验钢摩擦磨损行为进行了分析,讨论了磨损过程中的磨损机制。结果表明,随着淬火温度由850 ℃升高至1050 ℃,试验钢的强度、硬度和韧性整体呈现先升高后降低的趋势,900 ℃淬火时的强韧性最高。900 ℃淬火+200 ℃回火后,试验钢的磨痕宽度和深度最小,平均磨损面积也最小,磨痕形貌主要由犁沟和剥落坑组成。随淬火温度的继续升高,试验钢的磨痕宽度和深度增加。试验钢的摩擦因数与表面硬度相对应,耐磨性能与硬度呈正相关。850~900 ℃淬火时试验钢的摩擦因数相对较小,表现出优良的耐磨性,在900 ℃淬火时具有最佳的强韧性与耐磨性能匹配。

Abstract: 27CrMnB track steel was subject to quenching at different temperatures and tempering at 200 ℃, the mechanical properties of the steel under various quenching temperatures were investigated, and the friction and wear behavior was analyzed in terms of depth and width of wear scratches, wear volume and friction coefficient, as well as the wear mechanisms during the wear process were also discussed. The results indicate that as the quenching temperature increases from 850 ℃ to 1050 ℃, the strength, hardness and toughness of the steel first increase and then decrease, with the highest strength-toughness combination achieved at quenching temperature of 900 ℃. After quenching at 900 ℃ and tempering at 200 ℃, the steel exhibits the smallest width and depth of wear scratches, so that the average wear area is the smallest, meanwhile, the wear scratch morphology primarily consists of ploughing grooves and spalling pits. As the quenching temperature further increases, the width and depth of wear scratches increase. The friction coefficient of the steel corresponds to the surface hardness, and the wear resistance is positively correlated with hardness. The steel quenched at 850-900 ℃ shows relatively lower friction coefficient and excellent wear resistance, and the steel quenched at 900 ℃ possesses the optimal matching of strength, toughness and wear resistance.
