Application of active powders at fluidised bed heat treatment technologies
Babul, T. Application of active powders at fluidised bed heat treatment technologies / T. Babul, N. Kucharieva // International Journal of Microstructure and Materials Properties. - 2014. - Vol. 9, №1. - P. 50-59.
The paper describes the principles and conditions of carrying out of a new type of fluidised bed thermochemical treatment in chemically active powders with different ways of fluidisation. These new fluidised bed thermochemical treatments in chemically active powders are primarily for the formation of surface diffusion layers on parts made of constructional and tool steel. This method can be used for sherardising, alitising, carbonitriding, nitrocarburising, carburising or boronising. Characteristics of chemically active powders are compared with the chemically inert powders, used in conventional fluidised bed treatment.
