Abstract

"PESO DE PRECISãO DE SUPERFìCIE ENDURECIDA E PROCESSO DE FAZER O MESMO". Um peso de precisão (1) possui uma permanência de massa maior devido a uma camada de superfície endurecida que fornece resistência maior ao desgaste e arranhão. A camada de superfície endurecida é uma camada de difusão de concentração aumentada de carbono e/ou nitrogênio resultando em um tratamento térmico sob atmosfera de gás.
