Document Type and Number:
Japanese Patent JP2607980
Kind Code:
B2
Abstract:
A sliding member is sulphonitride by heating at 480 - 600 DEG C in the presence of both 10 - 500 ppm of a hydrogen sulfide gas and a 20 - 70 vol% ammonia gas, or by a method which comprises performing a primary heat treatment on the sliding member at 450 - 540 DEG C in the presence of 50 - 200 ppm of a hydrogen sulfide gas and a 10 - 70 vol% ammonia gas, then ceasing the supply of the ammonia gas, slowly reducing the temperature to a level of 200 - 350 DEG C, and performing a secondary heat treatment at that temperature level. By the either method, the sliding member having a FeS2 on its topmost surface can be obtained.
