Sintered tin-containing cobalt-based and nickel-based alloys

摘要

A sintered material and a method for the production thereof is described. The material comprises an alloy selected from one of the groups having a composition comprising in weight %: either Cr 5-30/Mo 0-15/Ni 0-25/W 0-15/C 0-5/Si 0-5/Fe 0-5/Mn 0-5/others 10max/Co balance, or Cr 10-20/Mo 0-15/Co 0-20/W 0-5/Fe 0-20/Al 0-5/Ti 0-5/others 15max/Ni balance; said alloy having incorporated therein from 3-15 weight % of Sn; and optionally from 1-6 weight % of a solid lubricant material.
