| Popis: | It has been shown that ion nitriding of hard alloys in hydrogen-free medium leads to an increase of the average value of microhardness to 20.1 GPa and a rise of the breaking load by 15% at cantilevered bending. The turning of steels using nitrided inserts results in the reduction of the friction coefficient and the cutting force to 10% of their corresponding values before nitriding, and the decrease of wear rate by half. The efficiency of nitriding is confirmed by production tests during the finish and rough machining. |
