Abstract:过盈配合界面在再制造拆解过程中，易形成划痕、犁沟、黏着堆积等干摩擦损伤，增加修复成本，降低再制造品过盈联结的可靠性。为降低界面拆解损伤，将表面织构引入配合表面，以 KMN 与 40CrNiMo7 为材料对象，通过试验研究了圆形凹坑织构对界面拆解损伤的影响。发现因织构的存在，降低了拆解滑动表面上的游离磨粒数量，界面拆解损伤明显减弱。且由承载能力试验发现，该织构能有效提高配合面初始承载能力。在结合面压力 50～200 MPa 范围内，织构表面的静摩擦因数(μ)较无织构表面提高了 0.1 左右。但拆解导致的微观划痕破坏了织构周边的环状熔融区，使得 μ 随拆解次数的增加而递减，经过两次再制造拆解模拟试验后，织构表面的 μ 值仅高于无织构表面 0.01～0.03。
