Most elements of ship machinery parts are regenerated during the cruise ship. Engineer often regenerates cylindrical outer surfaces (for example torque pump shaft neck). The welding technology of applying alloy and composite coatings is very common. The technology of infrasound thermal spraying of metal matrix composite coatings was presented. It is a simple technology and a very useful one in ship machinery regeneration during the cruise craft (e.g. internal combustion engines, torque pumps, separators). The metal matrix composite coatings must undergo finishing due to high surface roughness after application. The most popular is machining (e.g. turning or grinding). The authors also propose the application of finishing through turning. The paper should influence of the type of inserts on the geometric structure of the alloy Ni-5%Al and composite Ni-5%Al-15%Al2O3 coatings. Nickel - aluminium matrix composite coatings on were sprayed with a torch Casto-Dyn 8000 a steel substrate, and then turned lengthwise. In order to determine the optimum geometry of indexing, it is now synonymous with the selection of the optimum shape and dimensions of the insert and an appropriate holder. The insert was used in different shapes and geometries: square, triangular, trigon, made tungsten carbide and cubic boron nitride (CBN).
