8. Conclusion

Wear debris is an important factor in analyzing surface damage in a tribological context. It often provides valuable clues that can be used to establish a damage scenario or preventive maintenance plan. It can be useful for all industrial sectors, from the analysis of lubricants (unused and used) to the analysis of synovial fluid. There are many sampling and analysis techniques, but they are often complementary. A good methodology makes it possible to obtain data rich in information while rationalizing its cost. A judicious choice of parameters or descriptors should provide a rapid diagnosis and enable the creation of relevant databases. Furthermore, the integration of artificial intelligence into tribology represents a major advance, both for in-depth analysis of wear and friction mechanisms and for optimizing materials and extending component life. It paves the way for the development...
