ABSTRACT:
Brazing alloys used in a method of brazing at least two steel components into an integral part during a carburizing treatment followed by a quenching treatment are disclosed. These alloys should be in a liquid phase during the carburizing process in which the steel components with a brazing alloy placed therebetween are carburized at a temperature of approximately 930.degree. C., and in a solid phase at a temperature of approximately 850.degree. C. attained immediately before the quenching treatment. A Cu--Mn brazing alloy containing at least from 55 to 80 weight % of copper and from 20 to 45 weight % of manganese or a Cu--Mn--Ni brazing alloy containing at least from 20 to 45 weight % of manganese and from 0 to 15 weight % of nickel are suitable for the simultaneous brazing and carburizing process.
