FINDINGS
: When a composite clad powder of the ZrO<sub>2</sub>–Al system is sprayed onto the valves of an internal combustion engine, exothermic reactions occur in the coating, which increase the enthalpy of the sprayed material and the adhesion of coatings. The use of a composite clad powder of the ZrO<sub>2</sub>–Al system during coating deposition gives a greater heat-shielding effect compared to the Ni–Al sublayer and makes it possible to significantly increase the adhesion and thermal cycling resistance of heat-shielding coatings.
