| Popis: | We present results of a study of the microstructure of a ZrB2-containing combined laser–electric spark coating deposited on a titanium alloy and subjected to wear with a nonrigidly fastened abrasive performed by scanning electron microscopy in combination with an electron-probe microanalysis. It is established that the coating is characterized by a gradient microstructure over the thickness, and its subsurface layer is modified by Zr, O, Si, and C additives. We put forward the assumption that an increase in the hardness of the coating after abrasive treatment is due to its plastic deformation with the fragmentation of the structural elements and alloying with the indicated additives. |
