Opis:: In this study, pack boronizing was applied to ash-blowing nozzles manufactured from AISI 1040 steels using Ekabor II powders as the boronizing source at a temperature of 1273 K for a duration of 8 h. Erosive wear tests of boride ash-blowing nozzles were carried out in ash delivery line of thermal reactor under actual working conditions. It was observed that erosive wear resistance of borided ash-blowing nozzles were increased 3 times as a result of the boronizing process. The improved wear resistance of the borided samples can be explained by increased surface hardness and higher work hardening.

Opis:: In this study, the effects of perlite addition on mechanical properties and wear resistance of alumina ceramics were investigated. Alumina powders including perlite 5%, 10%, 15%, 20% and perlite free were prepared. These powders were shaped as rectangular by using uniaxial pressing system under the load of 100 MPa. The samples were sintered at 1400°C-1550C for 2 h and were subjected to some mechanical tests such as hardness and fracture toughness. X-ray diffraction analysis was employed to determine the crystalline phases. Bulk densities of the samples were measured. In addition, erosive wear test was performed to investigate the erosive wear resistance of the samples. The wear test results were presented depending on different sliding speed and sintering temperature. These results showed that perlite addition has a positive effect on erosive wear resistance of the alumina ceramics, generally.
