Abstract
PURPOSE: To eliminate problems such as viscosity, evaporation of a bath, life of a pot, removal of an adhered salt or the like, in a method for immersing a material to be treated in a molten bath of a salt containing a substance based on an element of the VI a group of the Periodic Table, by using a mixed salt bath agent consisting of a neutral salt and borate in a specific ratio.
CONSTITUTION: A mixed salt bath agent obtained by adding 5W30mol% borate to a neutral salt and, for example, one or more of a Cr element or a substance containing Cr are melted. In this molten bath, a material to be treated is immersed to form a Cr carbide layer on the surface thereof. In this case, one kind or more of the neutral salt may be added and as the neutral salt, NaCl, KCl, LiCl, CaCl2 or the like are used. When an amount of borate is below the lower limit, the evaporation of the bath is high and the deterioration thereof is fast and, when exceeds the upper limit, viscosity of the bath is high, pot life is short and removal of the adhered salt is difficult. In addition, when, as the acid salt of the element belonged to the VI a group, for example, Na2CrO4 or the like in an amount of about 2W10wt% is added, effect is enhanced.
