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.

This document discusses the manufacture and characterization of boron oxide solid lubricant coatings using radio frequency magnetron sputtering. It describes various boron-based coating types and manufacturing methods. The document outlines problems encountered in reproducibly manufacturing boron coatings, such as residual stresses. Solutions applied included multi-layer manufacturing and the addition of a carbon interlayer. The document summarizes the characterization of manufactured films and their physical properties. It concludes that multi-layer application can reduce residual stresses and established manufacturing methods allow for ease of production and molecular structure modification.

The Functional Attributes and Utilization of Borates in Lubrication Nanotechnology
Now this has my attention. Can you see why I'm fascinated by this figure? It's
not the rare Snub Truncated Octahedron because it has seven-sided openings:

I can find all that and I don't even know what a pin test is.
