Abstract:
A method of producing a wear resistant mechanical component, comprising the steps of:i) providing a component preform by placing a wear resistant tip of flat shape on a metal body capable of austenitic transformation with a brazing material interposed therebetween, the wear resistant tip having a smaller coefficient of thermal expansion than that of the metal body;ii) heating the component preform up to a brazing temperature higher than an austenitic transformation temperature of the metal body to thereby subject the metal body to austenitic transformation;iii) controlling the amount of austenitic transformation of the metal body based on a preselected target crown value of the wear resistant tip; andiv) causing the heated component preform to be cooled down to a normal temperature so that the wear resistant tip can be deformed into a crown shape and can have the target crown value.
