Tribochemistry of Bismuth and Bismuth Salts for Solid Lubrication

open access: yesACS Applied Materials & Interfaces, 2016
One of the main trends in the past decades is the reduction of wastage and the replacement of toxic compounds in industrial processes. Some soft metallic particles can be used as nontoxic solid lubricants in high-temperature processes. The behavior of bismuth metal particles, bismuth sulfide (Bi2S3), bismuth sulfate (Bi2(SO4)3), and bismuth oxide ...
