Laser-Induced Breakdown Spectroscopy in Africa

Laser-induced breakdown spectroscopy (LIBS), known also as laser-induced plasma spectroscopy (LIPS), is a well-known spectrochemical elemental analysis technique. The field of LIBS has been rapidly matured as a consequence of growing interest in real-time analysis across a broad spectrum of applied sciences and recent development of commercial LIBS analytical systems.

A typical cross section of an index guided PCF is shown in Fig 14 and 15. The PCF consists of a triangular lattice of air holes where the core is defined by a “missing” air hole. The pitch is labeled Λ, and measures the period of the hole structure (the distance between the centers of neighboring air holes).

Alloying elements. C influences hardness (higher content increases abrasive wear). Low carbon content, < 0.2%, increases adhesive wear, which will lead to built-up edge and bad chip breaking. Cr, Mo, W, V, Ti, Nb (carbide formers) increase abrasive wear.. O has a large influence on machinability; it forms non-metallic, oxidic and abrasive inclusions.. Al, Ti, V, Nb are used for the fine
