| Abstract: | Wear elements in engine oil play important roles in the normal operation of engines. Real-time detection of wear elements in engine oil can prevent engine from wearing and predict accidents. Therefore, the detection of wear elements in oil has important application value. The key problems of atomic spectroscopy in oil detection are summarized. The research advances of laser induced breakdown spectroscopy (LIBS) and other techniquesof atomic emission spectroscopy in oil sample detection are pointed out.The advantages and disadvantages of various techniques are analyzed. The advantages of LIBS technology in oil detection are introduced, and then indirect ablative LIBS technology is introduced. The technology of indirect ablative LIBS not only preserves the advantages of LIBS technology itself, but also improves detection sensitivity greatly. The use of indirect ablative LIBS technology to detect wear elements in oil has a great application prospect. The application of this technology in field detection is prospected. |
