Lubrication potential of boron compounds: An overview

Boron compounds are emerging as promising materials for a wide range of applications in automotive and industrial lubrication systems. Several studies conducted on boron compounds have revealed that they exhibit desirable properties for preparing stable and compatible lubricant components for a new generation of lubricating oil formulations. Boron‐containing lubricants have major tribological advantages, such as antiwear efficiency, good film strength, high‐temperature resistance, and self‐lubricating properties. The increasing number of patents concerning boron‐containing lubricants illustrates commercial interest in this area. Boron lubricants can be used in many forms, such as oxides, esters, and boric acid. Therefore, it can be expected that a new generation of lubricant formulations includes boron compounds. This paper presents an overview of various solid and liquid lubricants containing boron as an important ingredient, and is intended to aid the development of new lubricants.     

Effects of solid lubricants in backward extrusion

In the present paper, some solid lubricants were tested in backward extrusion friction tests with flat-headed punches using aluminium at room temperature. The results showed that anti-seizure ability was improved when wax was added to the solid lubricant samples. In addition, a water-based graphite lubricant and an ultrahigh molecular weight polyethylene (UHMW-PE) lubricant were tested using aluminium workpieces heated to 500°C. The lubricity of the UHMW-PE lubricant was found to be superior to that of the graphite lubricant.     

Solid lubrication of ball bearings for spacecraft mechanisms

The advantages of solid lubricants over oils and greases for the lubrication of ball bearings in spacecraft are briefly discussed.

Three specific lubricants, which account for the majority of applications: ptfe-composite, rf-sputtered MoS₂ and ionplated lead film, are first discussed and then compared in terms of durability and torque characteristics. It is concluded that any of these solid films may be acceptable, depending upon the required bearing duty. The limitations of each lubricant are considered and compared     

固体颗粒对低黏度介质润滑特性的影响

基于水-固两相单流体模型,研究润滑过程中的固体颗粒对低黏度润滑介质的影响。以无限宽楔形滑块为计算模型,推导出特定假设条件下考虑惯性力和界面滑移的低黏度介质润滑的雷诺方程,并通过不同条件下雷诺方程的求解,探讨固体颗粒含量对低黏度介质润滑特性的影响。结果表明:在对低黏度介质润滑特性进行研究时,需考虑其惯性力和界面滑移影响;固体颗粒的存在一定程度上增大润滑膜的压力和承载能力,颗粒含量越大,承载能力越大,但颗粒含量对润滑膜整体的压力分布状态几乎不会产生影响;惯性力增大固体颗粒对润滑介质的影响程度,而界面滑移减小固体颗粒对润滑介质承载能力的影响,发生滑移时,颗粒基本不影响润滑膜的承载能力。     

Next generation lubrication system for weapons

Current weapon system lubricants have performance limitations in extreme climatic conditions, specifically in sand and dust and cold environments. An alternative solid lubricant based lubrication system was investigated and validated using the ASTM subscale tests. The solid lubricants were selected and evaluated based on weapon system lubrication requirements. The solid lubrication systems were evaluated for coefficient of friction, wear, load carrying capacity, endurance (wear) life and corrosion resistance. The novel lubrication system showed superior subscale performance compared to current gun lubricants. It has the potential to provide much better performance than current gun lubricants, especially in sand, cold and humid environments.
