Nomograms to Determine the Controlling Factors in Vacuum-Carburizing Regimes

Resumo

A method based on computer evaluation of mechanical properties and a mathematical model of vacuum carburizing are used for creating two nomograms, i.e., (1 ) for determining the parameters that the carburized layers of gears of steel 16Kh3NVFMB-Sh must have to obtain the required service properties and (2 ) for determining the values that the factors in periodic carburizing regimes must have to ensure that the layers have the prescribed parameters. The nomograms are used to determine the factors for two gears that are to undergo vacuum carburizing.
