Περίληψη
Materials that are durable and wear-resistant are essential for the successful operation of machines and equipment in the industrial sector. However, even the toughest materials can succumb to wear and tear over time, particularly when exposed to erosive forces. The lecture presents the results of research on the possibility of shaping the structure and properties of cobalt-based alloys (type Stellite 6) fabricated by laser cladding in order to increase their erosion resistance. Effect of the concentration of elements in the Co-Cr-W-C-Ti alloy on the possibility of in situ synthesis of titanium carbide was subjected to a detailed analysis. In particular, the effect of the addition of titanium and carbon on the ability to control the reinforcing phase content and morphology was investigated. The commercial Co-Cr-W-C coatings as well as composite coatings reinforced by in situ synthesis of TiC phase were subjected to erosive wear resistance tests with the determination of mechanism of erosive wear.
