ABSTRACT:
A method of making a bearing component for a rotary cone rock bit which obtains the beneficial strengthening effect of metalloids and their compounds without the undesirable effects of segregation. The method includes rolling a sintered compact to form a strip or plate of a particular composition that would be subject to segregation if produced by casting and thereafter forming the strip or plate into the bearing component. Additionally, the rolled sintered compact may be heat treated and machined after heat treating. A method of making a rotary cone rock bit is also disclosed.
