Resumen:
The aim of this study was to analyze the frictional behavior of a bismuth based soft coating, developed using a novel, eco-friendly and economically competitive synthesis. Bismuth has a non-toxic nature, making it attractive for the development of new tribological applications such as coatings or as oil additives.Bismuth sulfide (Bi2S3) nanoparticles were synthesized in-house by means of an eco-friendly reaction in an aqueous medium under mild reaction conditions, in presence of a surfactant. The obtained particles were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).The Bi2S3 nanoparticles were deposited as a coating using a burnishing technique. As a comparison, burnished coatings from commercially available MoS2 powder were also deposited under the same conditions.
