The Influence of the Carbon Content on the Depth of the Carbonitrurat Layer in Fluidized Layer for 1C15, 1C25 and 1C45 Steels
MetadataShow full item record
This paper presents the experimental research of carbonitriding thermochemical processing in fluidized layer performed on some samples of carbon steel with different carbon contents, the fluidized layer being made up of a mixture of quartz sand and gases (methane, ammonia and air). The thermochemical treatments have been carried out over a time period of two hours and thirty minutes for all temperatures considered for the study. An important parameter of this type of thermochemical processing was also represented by the ratio of methane and ammonia that influenced the final results of the research. The research results revealed the influence of the carbon content of the steels investigated on the thickness values of the carbonitrided layer for samples investigated.
