“…According to the friction model in Equations ( 2)- (10), when there is no preload or the positive load is more than twice of the preload (i.e., the preload fails), the friction increases with the increase of slider's positive load, and the dynamic friction factor remains unchanged. However, this is not completely consistent with the actual measurement.…”

“…It was found that two process textures tested at the low temperature led to a smaller final coefficient of friction, compared to one process surface; the opposite results were obtained at a high temperature. Yang et al [10] studied the influence mechanism of volcanic texture on the tribological behavior of textured coating surface. The results showed a volcano-shaped texture with a suitable diameters and area ratios which were conducive to lowering the friction coefficient and reducing adhesive wear.…”

During the operation of the guide rail pair, the accuracy of the guide rail pair is decreased by friction and wear, and the overall performance of the machine tool is directly affected. The influence of surface micro-features of the slider raceway on the dynamic friction factor of the guide rail pair is analyzed in this paper. The relationship between the geometric characteristics of the surface micro-features and the dynamic friction factor is studied, and a prediction model of the dynamic friction factor is established. Meanwhile, the correctness and rationality of the predicted model is verified by the orthogonal experiments of the friction force. It is found that the dynamic friction factor increases with the increase of the groove depth, the height of the peaks and peak–valleys on the surface of the slider raceway. The above research provides a basis for the study of the friction and wear characteristics of guide rail pairs and lays a foundation for improving its friction and wear performance.

“…Many studies have been conducted to overcome the higher friction behavior of these coatings by designing unique coating architectures and doping and alloying various elements without degrading the mechanical and thermal stability. Interestingly, Yang et al [13] achieved enhanced tribological properties of AlCrN coatings fabricated on volcano-shaped textured surfaces. These unique structures substantially reduced the real contact of sliding surfaces as well as the wear particles trapped between the textured surfaces, resulting in less frictional force and wear.…”

Hard and wear-resistant coatings created utilizing physical vapor deposition (PVD) techniques are extensively used in extreme tribological applications. The friction and wear behavior of coatings vary significantly with temperature, indicating that advanced coating concepts are essential for prolonged load-bearing applications. Many coating concepts have recently been explored in this area, including multicomponent, multilayer, gradient coatings; high entropy alloy (HEA) nitride; and functionally modified coatings. In this review, we highlighted the most significant findings from ongoing research to comprehend crucial coating properties and design aspects. To obtain enhanced tribological properties, the microstructure, composition, residual stress, hardness, and HT oxidation resistance are tuned through doping or addition of appropriate materials at an optimized level into the primary coatings. Such improvements are achieved by optimizing PVD process parameters such as input power, partial pressure, reactive gas flow rates, substrate bias, and temperature. The incorporation of ideal amounts of Si, Cr, Mo, W, Ag, and Cu into ternary and quaternary coatings, as well as unique multilayer designs, considerably increases the tribological performance of the coatings. Recent discoveries show that not only mechanical hardness and fracture toughness govern wear resistance, but also that oxidation at HT plays a significant role in the lubrication or wear failure of coatings. The tribo-induced metal oxides and/or Magnéli phases concentrated in the tribolayer are the key governing factors of friction and wear behavior at high temperatures. This review includes detailed insights into the advancements in wear resistance as well as various failure mechanisms associated with temperature changes.

“…Some crucial frictional components of marine equipment serve directly in seawater, such as pumps, hydraulic systems, bearings, shafts, propellers, etc [1], and how to improve the tribochemical performance of these components in seawater is a current research hotspot. Nitride hard composite coatings deposited by physical vapor deposition (PVD) techniques have been found to be an effective solution due to its high hardness, excellent wear resistance, oxidation resistance, and chemical properties [2][3][4][5][6]. Among these nitride coatings, Ti-based coatings have been most extensively investigated [7][8][9][10].…”

In order to study the effects of friction surface and electrochemical properties on tribological behavior of TiAlSiN coating in seawater, the frictional experiments are investigated and compared in air and seawater using ball-on-disk method with Si3N4 ball as a counter material. The results show that the wear rates are both decreased compaired with 316L substrate in two environments and the TiAlSiN coating presents excellent protective efficiency. In dry friction environment, the abrasive debris can not be discharged in time resulting in a rough aggregate surface which will accelerate wear of the coating. Although seawater is corrosive, the friction oxides form a lubricated barrier surface in the friction process which can greatly reduce the wear rate. In addition, excellent electrochemical properties and the dense, refinement nanostructure improve tribocorrosion resistance of the coating in seawater. It proves that friction surface has a great impact on the tribological performance of TiAlSiN coating, how to form a more beneficial friction layer in the tribochemical environment is worthy of further research for Marine equipment.
