Abstract : An investigation was conducted in order to determine and recommend optimum atomic absorption procedures for the analyses of wear metals in lubricating oils. The investigation involved determining the optimum sample preparation procedures and optimum nitrous oxide-acetylene flame conditions that will provide wear metal determinations of the desired accuracy and precision. Also included in this report is a summary of the research conducted to develop an analytical procedure that will quantitatively recover wear metal particles regardless of their size. The method presented herein involves adding an acid mixture to the lubricant which dissolves the metallic particles present.
