Special Issue Information

Dear Colleagues,

Friction, wear, and damage are integral factors that have a profound impact on the performance, longevity, and safety of numerous engineering systems and applications. However, the intricate nature of their underlying mechanisms and interdependencies pose significant challenges for researchers. To overcome these challenges, advanced modeling techniques, rigorous experimental methods, and innovative material developments are imperative. This Special Issue is dedicated to the latest advancements in the field of "Engineering Materials: Friction, Wear and Damage." We invite submissions encompassing experimental, analytical, or numerical studies, particularly those focused on, but not limited to, the following topics: tribology, lubrication, materials science and engineering, surface engineering, contact mechanics, biomaterials and tribology, fatigue and structural failure, and damage analysis. Through these contributions, we aim to deepen our understanding of these critical phenomena and explore new approaches to mitigate their adverse effects.

During petroleum drilling, the reciprocating motion in the seal device leads to piston and sleeve wear, which may cause leakage of the sealing medium. Selecting appropriate materials for the piston and sleeve, along with surface modifications, can effectively prolong the seal service life of the seal. The friction and wear properties of piston and sleeve pairs of different materials in a metal sealing device were simulated by the laboratory “pin-on-block” reciprocating friction test. Pins made of 45# steel, 35CrMo, and 20Cr13 were used to simulate piston bulges, while 35CrMo samples were used to simulate sleeves. Additionally, the influence of DLC (diamond-like carbon) coating and QPQ (Quench–Polish–Quench) nitriding on the wear resistance of the materials was studied. Based on this, the friction and wear properties, along with the wear mechanism of different material pairs, were analyzed. The results show that the friction coefficient curves of the three piston base materials and the 35CrMo sleeve are similar, and the friction coefficient of 45# steel is lower than that of 35CrMo and 20Cr13 at the initial stage. The DLC surface coating exhibited the best anti-wear performance, with the lowest friction coefficient, minimal wear, and the most stable friction coefficient. Surface QPQ nitriding treatment can also improve the wear resistance of the base material. However, due to the oxide formed during nitriding being prone to flaking, the friction coefficient fluctuates significantly at the initial stage of testing, and its anti-wear performance was inferior to that of the DLC coating. This study on material pairing and surface modification provides theoretical support for material selection and surface modification design of pistons and sleeves in oil drilling sealing devices.
