摘要:
High theoretical density, metal-based materials containing graphite or hexagonal boron nitride have low coefficients of friction and wear rates are useful for bearings, bushings and other articles subject to bearing loads.
摘要:
A method of converting metal-containing or metal alloy-containing compounds into a metal or metal alloy by rapidly heating the metal-containing or metal alloy-containing compound to an elevated temperature to instigate conversion and holding the metal-containing or metal alloy-containing compound at the elevated temperature for a time sufficient to effect formation of the metal or metal alloy is an efficient and economical method of producing metals and metal alloys.
