TLDR
In this paper, the effect of sliding speed (1·0 −2·5 m s−1) on the friction and wear performance of nitrided martensitic stainless steel in the presence of dry lubricants like boric acid and MoS2 has been investigated.Abstract:
Sliding counter bodies frequently undergo boundary lubrication at lubricant starved areas with dominated surface interaction under dry sliding condition. The effect of sliding speed (1·0–2·5 m s−1) on the friction and wear performance of nitrided martensitic stainless steel in the presence of dry lubricants like boric acid and MoS2 has been investigated, and the results are presented in this work. Under dry condition, wear loss increases and friction coefficient decreases with sliding speeds. The lubricant coated samples show minimal wear loss at all sliding speeds (2·5 m s−1). The friction coefficient shows a decreasing trend for the MoS2 coated sample, while the boric acid coated sample shows an increasing trend. This is possibly due to the temperature induced conversion of boric acid to boric oxide. The fine debris mixture formed during sliding may also pin the lamellar shearing of solid lubricants to increase friction.read more

M Alper Yılmaz,Doğuş Özkan +1 more
TL;DR: The most commonly used anti-wear additive is zinc dithiophosphate (ZDDP) as discussed by the authors, which prevents the tribological system from wearing out due to friction and wear.

Tribology of naturally occurring boric acid films on boron carbide
TL;DR: In this article, the formation and self-lubricating mechanisms of naturally occurring boric acid films on boron carbide (B 4 C) substrates were described and the sliding friction coefficients of yttria/partially stabilized zirconia pins against plain B 4 C substrates are quite high at 0.3-0.4, but are 6-10 times lower against the B 4C substrates subjected to annealing at 800°C.
