Steel Part and Method for Manufacturing the Same

摘要

A plurality of layers are laminated on at least part of the member under treatment made of steel, the plurality of layers having carbon concentrations higher than that of the member under treatment and 1.0 wt. % or less, the carbon concentration of an outermost layer of the plurality of layers being the highest. A method for manufacturing a steel part, including spraying powder containing carbon on at least part of an member under treatment made of steel so as to form a first layer having a carbon concentration higher than that of the member under treatment and spraying powder containing carbon on at least part of the first layer so as to form a second layer having a carbon concentration higher than that of the first layer. Carbon concentrations of a plurality of layers including the first layer and the second layer are 1.0 wt. % or less.
