Molybdenum APS-Coatings
A Self-regenerative Solution for Wear Resistance in Dry-lubrication Applications
Abstract
Molybdenum coatings and their oxides are a promising technology to protect bearing surfaces from wear due to their good wear-resistance and their capability to regenerate by forming new protective and lubricious oxide layers. However, until recently, their applicability against higher hardness materials has not yet been studied. This study aims to explore Atmospheric Plasma Spraying (APS) to produce a molybdenum layer on bearing steel and compare the tribological behavior of coated and uncoated surfaces using a reciprocating pin-on-plate apparatus under dry-lubrication. The counter-body material was chosen to be alumina, given its inertness and high hardness. The tests were conducted at various distances and loads, comparing the friction and wear volumes of coated and uncoated specimens.
