内燃机活塞环在边界摩擦和半干摩擦条件下工作。较高的温度、变化的负荷、压力的可逆运动以及润滑材料的供给不足而对活塞环提出了复杂的要求：在保持所需的弹性和强度的条件下具有很高的抗磨性和抗擦伤性。本文探讨了用组织近似于铸铁的粉末合金制造活塞环的可能性。 Internal combustion engine piston ring in the boundary friction and semi-dry friction conditions. Higher temperatures, varying loads, reversible pressure movements, and insufficient supply of lubricating material present complex requirements for the piston rings: high abrasion resistance and abrasion resistance while retaining the required elasticity and strength Injuries. This article explores the possibility of making piston rings with powder alloys that have tissue approximations of cast iron.
