Abstract
In order to obtain uniform and standard layers of Fe2B on parts made of iron materials, the parts are heated with the boriding agent, initially only to 550 - 600 DEG C, after which a period is allowed until temperature equilibration takes place within the batch, and finally the batch is heated as rapidly as possible to the boriding temperatures of 850 DEG C or higher.
