Analysis of Wear Metals and Additive Package Elements in New and Used Oil Using the Optima 8300 ICP-OES with Flat Plate Plasma Technology
ثبت نشده
چکیده
The analysis of new and used oil for concentration trends of wear metals and for formulation or depletion of additive package metals has been around for over 30 years. Wear metals such as copper (Cu) and iron (Fe) may indicate wear in an engine or any oil-wetted compartment. Boron (B), silicon (Si) or sodium (Na) may indicate contamination from dirt or antifreeze leading to a failure. Additive elements such as calcium (Ca), phosphorus (P) and zinc (Zn) are analyzed for depletion which contributes to wear since these elements contribute to certain key lubrication characteristics. A sound maintenance program, which routinely measures metals in the lubricating oils, not only reduces the expense of routinely dismantling the components for visual inspection, but can indicate unexpected wear before component failure.

Impact wear can be defined as the wear of a solid surface that is due to percussion, which is a repetitive exposure to dynamic contact by another solid body. It generally has the devastating effects on the mechanical elements and causes the equipments to shift away from their normal performance. Impact wear has not been studied as extensive as other wear mechanisms and as a result information o...
