Abstract:

The possibilities of using the eddy-current method for testing the fatigue degradation under contact loading of NiCrBSi coatings were investigated. These coatings are obtained using the method of the gas-powder laser cladding from powders with different contents of chromium, boron, carbon, and additives of titanium carbide TiC (15 and 25 wt. \%). It was established that eddy-current testing of fatigue degradation under contact loading of PG-SR2 and PG-10N-01 coatings can be performed at high excitation frequencies of an eddy-current transducer, when the depth of the analyzed layer is maximally close to the thickness of the surface layer that was subjected to fatigue degradation. Testing the fatigue degradation under contact loading of TiC-PG-SR2 composite coatings with TiC-additive contents of 15 and 25 wt. \% has certain limitations and features that result from the presence of a significant number of discontinuity flaws in the structure of these coatings.
