Osipov M.Y. Research of the effect of alloys structural condition on their resistance to abrasive wear under elevated temperatures
Abstract
The paper reflects the results of alloys structural condition effect in terms of field tests under abrasive wear and ele-vated (up to 500 - 550 °C) temperatures. The tests were performed on mixer scrapers which mix refractory mass for pressing chamotte refractories. Scraper edges were subjected to intense abrasive wear and heated up to 550 °C at the result of friction with the skin of compressed re-fractory mass. Scraper plates installed at the same place and periodically replaced served as samples. The plates were made of high-speed steel Х12Ф1 and Х12 and then heat-treated to different structural conditions of matrix alloys containing vari-ous amounts of carbide phase. It was found that under conditions of abrasive wear and temperatures up to 550 °C the lowest wear resistance have the materials with ferritic matrix, while the highest wear resistance have predominantly materials with martensitic condition. Austenitic-martensitic alloys occupy intermediate position in wear resistance scale. It was established that carbide phase plays the most important role in wear resistance improving under such condi-tions. The test results demonstrate the existence of proportional relation between wear resistance and hardness, while under one type of matrix, - between the wear resistance and the amount of carbide phase.References
