Studies of the adhesion strength of an enamel reaction-hardening coating on a heat-resistant nickel alloy VZH171 by the sclerometry method have been carried out. The threshold value of the loads required for the occurrence of cracks in the pavement has been determined. The values ??obtained are high for this type of material and correspond to the level typical for chrome and nickel coatings. The results of microstructural analysis of the tested samples are also shown. Defects occurring in each zone of increasing load are described in detail.
