【 摘 要 】
Using experimental methods of analysis, the morphology,elemental composition and chemical state of hard alloys ofthe «TiC-TiNi» system in the initial state and after varioustypes of ion-beam treatment have been investigated. It isfound that the effect of a continuous ion beam leads to anincrease in the microhardness of the investigated alloysby 10–12 %. When samples are irradiated with a pulsedion beam, as a result of destruction of surface layers, themicrohardness value decreases by 20 %, as a result ofwhich this type of modification is not preferable for alloysof the TiC-TiNi system.
