The article discusses the issues of increasing resistance to brittle fracture of surgical scalpels with ceramic blades from nanostructured crystals of partially stabilized zirconium dioxide. The statement is substantiated that the strength properties of crystals can be increased by increasing the crack resistance of crystals by alloying with rare-earth elements. The kinetic microindentation method is used to study the characteristics of mechanical properties and crack resistance of samples of alloyed crystals. An assumption about the efficiency of alloying crystals with cobalt is substantiated. The bending strength test of promising crystal compositions is carried out. Based on the study, recommendations are formulated on the use of zirconium dioxide crystals for surgical scalpel blade manufacture.
