SINTERED MEMBER
Document Type and Number:
WIPO Patent Application WO/2013/122076
Kind Code:
A1
Abstract:
Provided is a sliding sintered member having excellent wear resistance under high-temperature environments and excellent oxidation resistance. In the sintered member, at least one component selected from a barium compound, a strontium compound, mica, an aluminum-silicon composite oxide and alumina is dispersed as a solid lubricant in a stainless alloy selected from an austenitic stainless alloy, a martensitic stainless alloy and a ferritic stainless alloy each containing 10 to 35 mass% of Cr, wherein the content of the solid lubricant is 3 to 50 vol%. As the solid lubricant, BaSO4, BaO, BaSiO3, BaNiO3, SrSO4, Sr2CrO4, sericite, phlogopite, mullite and alumina can be used suitably.
