ABSTRACT:
Sintered friction laminae are produced by scattering metal powder on a steel substrate and then sintering the powder/substrate article in a furnace with free nitrogen in the furnace atmosphere, which atmosphere is continually renewed. The nitrogen is produced by decomposition of ammonia and diffuses into the steel substrate to harden the steel.
