MONOLITHIC CERAMIC BODY WITH PERIPHERAL AREA FROM MIXED OXIDE AND METAL SURFACE, METHOD OF ITS OBTAINING AND APPLICATION Russian patent published in 2015 - IPC C04B41/88 C04B35/486 

FIELD: chemistry.

SUBSTANCE: claimed invention relates to monolithic ceramic body with peripheral area from mixed oxide and metal surface and can be applied as implant or protective means for people, vehicles, buildings or spacecraft. Ceramic body contains first metal (I) oxide (preferably zirconium or aluminium), peripheral area form mixed oxide, which contains oxide of first metal (I) and second metal (II), which has high affinity to oxygen (preferably titanium), and metal surface from metal (II) on peripheral area from mixed oxide. Peripheral area from mixed oxide contains continuous concentration gradient of first metal (I), starting from 100% in core and to 0% in transitional area to metal surface of ceramic body, and continuous concentration gradient of second metal (II) in reverse direction, counted per the total content of metals (I+II). Content of oxygen in peripheral area from mixed oxide remains constant, and monolithic structure of ceramic body does not contain borders of phase separation. Ceramic body is obtained by method of ionic implantation of metal (II) into ceramic body, which consists of metal (I) oxide.

EFFECT: increase of service term and work capacity of products.
