Nickel matrix coatings were sprayed by the Casto-Dyn 8000 torch on a steel substrate, and then subjected to
straight turning. Determining of the optimum geometry of indexing is now synonymous with the selection of the
optimum shape and dimensions of the insert and of an appropriate holder. According to cutting board, it was selected
square, triangular, trigon inserts, made of carbide and of cubic boron nitride (borazon). Machining of nickel-based
coatings was carried out for the cutting speed vc = 214 m/min in the case of treatment with borazon inserts,
vc = 107 m/min in case of plates treated with tungsten carbide cutting, using the feed f =0.06 mm/rev and the depth of
cut ap = 0.3 mm. Metal cutting the surface of steel samples coated with a composite coating containing 15% Al2O3
based on nickel, conducted for the cutting speed vc = 157 m/min when machining with borazon inserts and for
vc = 83 m/min inserts with tungsten carbide for feed f = 0.06 mm/rev and depth of cut ap = 0.3 mm. Highly precise
finishing of flame spraying composite and alloy coatings was carried out using turning by tool with borazon inserts.
Flank (VB) and attack (KB) of turning tool wear while maintaining a constant length of spiral cutting (LSC) were
determined. The effect of the shape and grade of inserts upon the geometric structure of the composite coatings and is
considered in the paper. The article can determine the shape and grade of inserts is necessary to obtain sufficient
quality of the shaft of centrifugal pumps with a composite coating.
