"High-temperature cyclic impact abrasion testing: wear behaviour of single and multiphase materials up to 750 °C";
Estonian Journal of Engineering, 15 (2009), 4; 359 - 366.

The aim of this work was to find correlations between selected microstructural parameters such as hardness, content of hard phases and coarseness of microstructure and the wear resistance at high temperatures. Two materials with different microstructures, showing promising high-temperature wear performance, were investigated under combined impact abrasion conditions at enhanccd temperatures using novel high-temperature cyclic impact abrasion testing apparatus. Results indicate that the wear rate increases with the increase ofthe test temperature. In multiphase materials, the matrix ability to bind hard phases at high temperatures as well as the matrix stability at high temperatures strongly influence the wear resistance. The test results indicate that at higher temperatures the ability to form compound layers may have a positive effect on wear performance.
