The abrasion failure is the key factor for prolonging the service life and energy saving of furrow openers. The hardness enhancement was reported to be an effective strategy to increase the wear resistance against the soil abrasion. D517 coatings were deposited on Q235 steel by electric spark to improve the wear-resistant property with an affordable cost for farmers. The wear behavior of the coatings was characterized in a pin on disk friction equipment and a homemade soil abrasion simulation system. The soil adhesion, which is highly related to energy consumption, was also evaluated. Results showed that D517 coatings revealed dendrite structure with some randomly distributed carbides. The electric current exerted a great influence on the microstructure, hardness, friction coefficient, and soil wear rate. The wear rate of samples deposited with 80 A and 90 A reduced to 79% and 84%, respectively, as compared with the normalized heat-treated 65 Mn steel after 6 h in soil. This work provides a promising solution to increase the wear resistance of furrow openers. It needs to be noted that the coating would increase the soil adhesion of the opener, which needs to be further explored to decrease the energy consumption.

“…[15] However, considering the rather complicated processing procedure and easy wear of the micro-grooves, this method still has many challenges. [16] Addition of fillers with high rigidity and low friction coefficient offers another facile route to improve the tribological properties in essence. [17,18] It was considered that the strong fiberrubber interface could enhance the overall fatigue strength, and thus improve the deformation stability.…”

Minimization and suppression of friction and noise in underwater bearings remains a key aspect in modern marine vehicle industry owing to the growing need for reliability, and passenger comfort. In this study, graphene nano‐flake (Gr) was introduced into the nitrile butadiene rubber (NBR) with assistance of ionic liquid (IL). Owing to the positive charge generated by the secondary ordering layer on the Gr surface, Gr were effectively exfoliate into few layers and uniformly dispersed in the NBR matrix. Accordingly, the friction coefficient and volume wear rate decreased to 0.3124 and 6.44 × 10−6 mm3·N−1·m−1 in the nanocomposite, depicting a 31.52% and 51.9% reduction than pure NBR. It was demonstrated that the reinforced hardness and the formation of tribological layer of Gr played a vital role in the lubricating mechanism where both deformation and the continuation of the stick–slip effect were prevented. As a proof of concept, the total vibration acceleration level of the NBR/GR‐IL composite decreased from 111.37 ± 5.57 dB to 79.68 ± 3.98 dB, exhibiting good noise and vibration suppression effect. This work not only broadens the application of GR‐based materials, but also shed some light on the designing philosophy to improve the efficiency, service life and safety of the future marine vehicles.

“…Litwin [10] compared two types of waterlubricated bearings via experiments, and the results obtained indicated that the three-layer sliding bearing with lubrication grooves in the upper part of the bush possessed optimal tribological properties. Bhardwaj et al [11], Dong et al [12], Sudeep [13], Yamada [14], Adamczak et al [15], and Yang et al [16] also carried out studies on the effect of texture on the vibration in various bearings, and obtained positive results.…”

As the first link element for the transmission of shaft vibration to the pedestal and even to the hull, water-lubricated bearing plays a key role in suppressing vibration. Although the porous structure is considered as one of the main methods for improving the wideband vibration and noise reduction performance of materials in many industrial fields, the studies in the field of water-lubricated bearing remain insufficient. To enhance vibration reduction performance, a fluid-saturated perforated slab is designed in this study, and via the establishment of a fluid-solid coupled vibration model, the influence law and impact levels were analyzed and verified by simulation and experiments. The results obtained verified that the total vibration amplitude of damping-enhanced stern bearing in the vertical direction was smaller than that of the normal stern bearing, and the reduction amplitude of the characteristic frequency agreed with the optimal value at approximately 0.1 of the volume fraction of the liquid phase when the solid-fluid phase was rubber–water. Additionally, the increase in fluid fraction did not enhance the damping effect, instead, it unexpectedly reduced the natural frequency of the raw material significantly. This research indicates that the design of the fluid-saturated perforated slab is effective in reducing the transmission of the vibration amplitude from the shaft, and presents the best volume fraction of the liquid phase.
