EURECA-PRO Invited Lecture at TUC by Asst. Pr. Tomasz Poloczek (SUT, Poland)

The Technical University of Crete (TUC), proud member of the European University on Responsible Consumption and Production (EURECA-PRO), organizes a series of open scientific lectures in the context of faculty exchange visits between partner universities. The 2nd lecture of this series is titled

"Shaping the Structure and Properties of Laser-Cladded Alloys
Characterized by High-Erosion Resistance"

and will be delivered by

Assistant Professor Tomasz Poloczek
Silesian University of Technology (SUT), Gliwice, Poland

on the following date/time

Monday September 18, 2023 | 11:00 EET (10:00 CET)

and can be attended either physically or virtually

Lecture Hall 145.Π58 @ Science Building, TUC Campus

The lecture is open to all interested members of TUC and EURECA-PRO.


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.
