Abstract
A solid lubricant for being embedded in pores or grooves formed at a sliding surface of a sliding member body, comprises 5 to 30% by volume of a polyethylene resin, 20 to 60% by volume of a hydrocarbon-based wax and 10 to 60% by volume of melamine cyanurate. Such a solid lubricant can exhibit sliding properties identical to or higher than those of lead-containing solid lubricants, even under high load conditions.
Claims12
A sliding member comprising a sliding member body, and a solid lubricant comprising 5 to 24% by volume of a polyethylene resin, 20 to 60% by volume of a hydrocarbon-based wax, 20 to 60% by volume of melamine cyanurate, and at least one compound selected from the group consisting of higher-fatty acids, higher-fatty esters and higher-fatty amides in an amount of 1 to 10% by volume, the solid lubricant having a friction coefficient of not more than 0.100,
- which is embedded in pores and grooves formed at the sliding surface of the sliding member body.
A sliding member comprising a sliding member body, and a solid lubricant comprising 5 to 24% by volume of a polyethylene resin, 20 to 60% by volume of a hydrocarbon-based wax, 20 to 60% by volume of melamine cyanurate, and a phosphate in an amount of 3 to 15% by volume, the solid lubricant having a friction coefficient of not more than 0.100,
- which is embedded in pores and grooves formed at the sliding surface of the sliding member body.
