Microhardness changes gradient of the duplex stainless steel (DSS) surface layer after dry turning

Blog Article

The article presents the gradient of microhardness Jeans changes as a function of the distance from the material surface after turning with a wedge provided with a coating with a ceramic intermediate layer.The investigation comprised the influence of usc trojans snapback hat 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 conditions during machining of parts for electric motors and deep-well pumps.
