MICROHARDNESS CHANGES GRADIENT OF THE DUPLEX STAINLESS STEEL (DSS) SURFACE LAYER AFTER DRY TURNING

The article presents the gradient of microhardness changes as a function of the distance from distance the material surface after turning with a wedge provided with a coating with a ceramic intermediate layer. The investigation comprised the influence of cutting speed on surface integrity microhardness in dry machining. The tested material was duplex stainless steel (DSS) with two-phase, ferritic-austenitic structure. The tests have been performed under production coditions during machining of parts for electric motors and deep-well pumps.
