Abstract

This study investigated the friction and wear characteristics of two super-hard coatings on M2 steel. One was A1MgB14, produced by pulsed laser deposition (PLD), and the other was a nanocomposite of A1MgB 14-TiB2 produced by physical vapor deposition (PVD). Tests were conducted under unidirectional and reciprocating sliding against AISI 52100 bearing steel in both dry and oil-lubricated conditions. The A1MgB 14, coating exhibited an encouraging but short-lived low friction stage (μ = 02) in dry sliding. The A1MgB14-TiB2 coating reduced the wear rates by one order of magnitude relative to the M2 steel and three orders of magnitude for the counterface in dry sliding. This nanocomposite coating also demonstrated significant extension (>2.SX) of the low friction (non-scuffing) stage when sliding under starved lubrication.
