Tribochemical effects during running-in of metals and alloys

The formation of third bodies of metallic alloys depends on the mechanical mixing of the first bodies, debris and the lubricant or the atmosphere. While many previous results on pure metals have shown that the formation of ‘mixed material’ decreases friction and wear, inclusive correlations between the properties of this layer (e.g. thickness, structural, mechanical, and chemical) and the tribological properties have not yet been studied rigorously
