Japanese Patent JP2009534533
Kind Code:
A
Abstract:
A method for diffusing titanium and nitride into a base material having a generally compact, granular microstructure (e.g., carbide). The method generally includes the steps of providing a base material having a generally compact, granular microstructure; providing a salt bath which includes sodium dioxide and a salt selected from the group consisting of sodium cyanate and potassium cyanate; dispersing metallic titanium formed by electrolysis of a titanium compound in the bath; heating the salt bath to a temperature ranging from about 430° C. to about 670° C.; and soaking the base material in the salt bath for a time of from about 10 minutes to about 24 hours. In accordance with another aspect of the present invention, the base material may further be treated with conventional surface treatments or coatings.
