Abstract:
The
tribological properties of water-soluble borate are evaluated using
four-ball machine and HQ-1 block-on-ring tribotester. The rubbed surface
is investigated using X-ray photoelectron spectroscopy and electronic
probe analysis. The tribological test results show that the
water-soluble borate has good lubricating performance and lad-carrying
capacity. The surface analyses show that the content of element boron,
nitrogen and sulphur in wear scar surface is well-distributed. The
borate reacted with the metal surface in friction process and produced a
complex film composed of organic nitrogen, boric aced, boron oxide, iron
disulfide, ferrous sulfate and tribopolymer, which is effective on
improving the antiwear, friction-reduction and load-carrying capacity of
water-based fluid.
Key words:
