Special Issue Information

Dear Colleagues,

Society today is facing the reality of energy loss and energy shortages. Friction phenomena are considered to constitute the principal cause of wear failure and energy consumption. In the field of tribology, the quest for ultra-low friction is a persistent goal of researchers. To accomplish this goal, it is necessary to explore the origin of friction, which has long been an object of study. In the last five years, research topics and projects around superlubrication have been very fruitful. On the one hand, different material systems have been explored and utilized by researchers. Conversely, the theoretical knowledge derived from tribology has been continuously improved. With the advancement of technology, material characterization methods and computer simulations, tribologists are focusing more on micro-level mechanisms. While the translation of the experimental results is still a problem, it is estimated that the results of these studies on tribology, if applied in practice, will have a very significant economic impact in the future offer huge potential for energy savings.

The aim of this Special Issue is to draw attention to the development of tribology and to focus on the use of green energy and sustainable human development. Content of this Special Issue encompasses a wide range of disciplines, including material science, chemistry, biomedicine, and mechanical engineering. We welcome scholars from different fields to contribute to the advancement of tribology via this Special Issue.

The articles published in this special issue include the following diverse topics:

  • Advanced Carbon Materials Lubrication and Applications
  • Disulfide Film Development and Challenges
  • Ultra-low friction status and friction origins
  • Ultra-lubrication mechanisms and challenges
  • Polymer lubrication applications and development

I look forward to receiving your contributions.

PEEK (Poly Ether Ether Ketone) is a high-performance thermoplastic polymer with excellent mechanical, thermal and chemical stability. PEEK has good performance, and is widely used in hydraulic motors. However, there are few studies on the friction and wear properties of materials under the condition of oil lubrication with wide application. The modification of PEEK and the expansion of its application have become a hot research topic in the industry. This study focuses on the modification of the design of PEEK and explores the friction and wear characteristics of self-lubricating materials under different modification schemes. Friction and wear samples were prepared using PEEK-modification pelletizing and injection-molding processes, followed by fixed-condition friction and wear tests. The tribological mechanisms and wear properties of the materials under different modification schemes were analyzed, leading to the identification of several sets of improved reinforced materials. Experimental results demonstrate that modified materials can enhance surface tribological performance, with the best modification effect observed at an SCF filling rate of 15%. The modified PEEK material can better meet the requirements of specific applications, such as high-temperature environments, chemically aggressive environments, or applications requiring high strength and wear resistance.
