Elements determination in viscous lubricants

 	

Elements determination in viscous lubricants

The following elements can be included in additives: Zn, P, Ca, S, Mg, Ba, Sr, Mo, Cu. Their quantity is sufficient to be determined with XRFA directly without any sample preparation.

Elemental composition can be monitored at the production stage for composition control, as well as for wear-out control of friction units by determination of metal content in lubricant.
 
Boxol analysis in journal box bearings of locomotives is and example. Fe, Cu, Cr and Si are determined. High Si content indicates leakage in the bearings and requires lubricant change. High content of Fe, Cu, Cr  indicates of the bearing wear-out.

Element content determination is direct: sample cup with analyzed material is covered with polyethyleneterephtalate film and analyzed in a spectrometer.
