Abstract
The influence of carbon and the type of forms on the wear resistance, hardness and strength of samples from chromium iron made of ИЧХ18ВМ cast iron was investigated. The analysis of the structural structure of the samples of cast iron ИЧХ18ВМ depending on the type of shape and amount of carbon was made. It is established that regardless of the type of forms with increasing carbon content the formation of large primary carbides is observed, and then the emergence of particularly large trigonal carbides in a hypereutectic iron was confirmed. It is shown that regardless of the type of forms the formation and growth of carbides are influenced by such factors as an increase in the carbon content and the rate of solidification. A comparison was made between the hardness, strength, and wear resistance of samples obtained at different heat exchange and solidification rates.
