  by ZhaoPeng Hao, Gang Cheng, YiHang Fan, He Lan 
  Abstract: Nickel-based alloy Inconel 718 is difficult-to-cut and diffused seriously in cutting process. Its structure contains many complex atoms, such as Ni, Fe, Cr, etc. it is of great significance to study its diffusion wear mechanism under micro conditions. In this paper, a molecular dynamics model based on Ni, Fe and Cr is established. Through Ovito visualization, the phenomenon of atomic displacement is found in cutting, and the mean square displacement is used to solve the diffusion coefficient, the pre exponential factor and the transfer energy of atoms. MD method is used to make vacancy, The gap formation energy of WC Co tool and workpiece at grain boundary and lattice, and the diffusion activation energy barrier were calculated. The diffusion mechanism of Ni, Fe and Cr atoms is revealed by comparing with the experimental phenomena.

• Simulation analysis and experimental study on the friction characteristics of hexagonal texture on the surface of PA66 material  
  by Wusheng Tang, Yu Fei Nie, Zhiyi Lu, Yingyu Du, Yaochen Shi, Ning Ding 
  Abstract: Starting from reducing the vibration and noise of automotive timing belt transmission systems, explore whether texture can improve the friction characteristics between non-metallic friction pairs, a hexagonal texture was designed and processed on a PA66 nylon plate to form a friction pair with chloroprene rubber material for reciprocating friction tests. By combining numerical analysis and experimental research, it is proved that hexagonal texture can improve the stress distribution and concentration strength of the friction interface between PA66 and chloroprene rubber materials during the friction process, inhibit continuous vibration of the interface, thereby reducing vibration acceleration amplitude and noise level. In addition, when the texture spacing is moderate, with the increase of texture width, the vibration reduction and noise reduction effects are more prominent, but the individual effect of texture depth is not significant. This is of certain significance for reducing the vibration and noise of synchronous belt transmission systems.

  by Zhihui Xing, Jinghan Liu, Zheng Tan, Na Wang, Lei Fan, Li Zhang 
  Abstract: Aluminium-magnesium alloys are widely used in the fields of automobiles, architecture, healthcare, and electronics. The surface facial mask can effectively inhibit the direct contact between the metal substrate and the corrosive medium, thus reducing the corrosion rate and preventing corrosion. Based on biomimetic principles, this study used a hybrid method of laser texturing and surface spraying to prepare a superhydrophobic surface with a micro grid

• Long term steady state friction and wear rate estimation of ZTA against AZ31 alloy under different bio- lubricants for hip prosthesis-An In-vitro study  
  by R. Nithyaprakash, Shankar Subramaniam, R. Naveenkumar, Gokul Anand R, S. Vasanth, Chander Prakash, Alokesh Pramanik, A.K. Basak 
  Abstract: In human hip joint replacements, proper selection of biomaterials combination plays major role in improving longevity of implants thus reducing revision surgery. The present study focuses on such biomaterial combination of ZTA against AZ31 alloy, in estimating bio tribological properties of friction and wear rate for long-term sliding distance of 40 km using Ball-on-Disc (B-o-D) tribometer. The bio-lubricants considered for current study includes saline solution, Ringer’s solution, distilled water, phosphate buffere saline (PBS) and sesame oil. The B-o-D load considered for current study is 20 N which is equivalent to human gait activities like normal walking, lifting 40 kg, carrying 25 kg and stairs down 25 kg. Among bio-lubricants considered, sesame oil exhibited least coefficient of friction (CoF) of 0.35 followed by Ringer’s solution, PBS, distilled water and maximum CoF of 0.42 is obtained for saline solution. Later, wear rate of biomaterial combination is obtained for all these bio-lubricants and it is found that sesame oil exhibited least wear rate (K) of 8.55x10-6 mm3/Nm and maximum wear rate of 1.25x10-5 mm3/Nm is obtained for saline solution bio-lubricant.

• Wear and Corrosion Properties of the Cr-Ta Coating Deposited by Electrospark Deposition on the CrNi3MoVA Steel  
  by Feng Gao, Jinpeng Yang, Guanglin Zhu, Minghuang Bi, Zijun Wang, Xiaoming Chen, Ce'an Guo, Jian Zhang 
  Abstract: A Cr-Ta coating with a thickness of approximately 30 ?m was deposited on a CrNi3MoVA steel substrate using electrospark deposition, and its wear and corrosion properties were investigated. The dense Cr-Ta coating with fine grains is composed of Cr2Ta and Fe-Cr solid solution and metallurgically bonded to the substrate. Compared to the CrNi3MoVA steel, the Cr-Ta coating exhibits higher hardness, lower friction coefficient and wear loss. The main wear mechanism of the CrNi3MoVA steel is adhesive wear while that of the Cr-Ta coating belongs to abrasive wear. Furthermore, in contrast to the CrNi3MoVA steel, the Cr-Ta coating has a corrosion current density reduced by one order of magnitude, a corrosion potential shifted by approximately 0.05 V in the positive direction, and an electrochemical impedance increased by six times. The results indicated that the Cr-Ta coating significantly enhances the wear and corrosion properties of the CrNi3MoVA steel.

• Wear and corrosion resistance of TiN and AlTiN coatings deposited on YW2 substrate  
  by Linlan Hu, Jinkun Xiao, Jin Du, Jian Sun 
  Abstract: TiN and AlTiN coatings were deposited on YW2 substrates using magnetron sputtering technology. The friction and wear behavior of the coatings and substrate when slid against a diamond indenter, as well as their corrosion behavior in a 3.5wt% NaCl solution, were investigated. The results indicate that TiN coating exhibits the lowest friction coefficient, the shallowest and smoothest wear scars, demonstrating the best wear resistance. However, despite AlTiN coating having the highest hardness, it also shows the highest wear rate. Owing to its amorphous crystal structure, AlTiN coating exhibits greater brittleness, leading to coating spallation during friction and thus lower wear resistance. Both TiN and AlTiN coatings significantly improve the corrosion resistance of the YW2 substrate, with AlTiN coating exhibiting the optimal corrosion resistance. The incorporation of aluminum contributes to the formation of a passive film on the coating, thereby enhancing corrosion resistance.
  Keywords: TiN coating; AlTiN coating; Wear resistance; Corrosion resistance.

• Characteristics of dynamic friction and stress distribution in the cold rolling interface of aluminum strip based on fractal theory  
  by Huajie Wu, Qiaoyi Wang, Laihua Tao, Jiang Xin 
  Abstract: This paper addresses the limitations of dynamic friction models in describing the force behavior at the cold rolling interface. Using fractal theory, rolling theory, and load distribution theory, the study decouples the solid-liquid contact forces at the interface. Experimental data provided fractal parameters for aluminum surface roughness. A dynamic friction factor model incorporating surface roughness and metal flow velocity was developed. The study investigates the friction force and stress distribution at the aluminum cold rolling interface, revealing the dynamic friction factor varies with load, increasing along the rolling direction, and shows a more significant rise in the entry zone. The friction coefficient exhibits a monotonic increase with load, especially at lower reductions. The peak stress does not align with frictional force direction changes. The model's calculations closely match experimental data, with minor discrepancies in the exit zone.
  Keywords: fractal theory; dynamic friction; rolling interface; stress distribution.
