Relevance:

The crankshaft is one of the expensive parts of the engine, largely determining its resource. During the operation of the engine, the rubbing parts of the shaft wear out, and fatigue damage accumulates in the most dangerous areas, resulting in a decrease in its strength and, in particular, resistance to fatigue loads. The development of new progressive technological processes for the restoration of crankshafts of internal combustion engines, as well as the improvement of existing methods that ensure a given engine life by creating wear-resistant coatings on the surfaces of their root and connecting rod necks, high economic efficiency of the engine, is currently an urgent task.

Target:

Development of technology for restoring crankshafts of internal combustion engines by creating wear-resistant coatings based on iron by supersonic arc metallization on the surfaces of their root and connecting rod necks, as well as studying the patterns of formation of the structure and properties of iron-based coatings during supersonic arc metallization.

Expectation:

1. The structural-phase states and tribological properties of iron-based coatings obtained by supersonic arc metallization will be investigated.

2. The regularities of the formation of the structure and properties of iron-based coatings during supersonic arc metallization will be studied.

3. As a result of the project, new data will be obtained on the relationship of the structure with the tribological properties of iron-based coatings obtained by supersonic arc metallization.

4. The technological process of restoration of worn surfaces of crankshafts of internal combustion engines by supersonic arc metallization will be developed.

5. A site for the repair and restoration of crankshafts of internal combustion engines will be created.
