Abstract
A wear-resistant iron-based sintered contact material is provided which is sintered by powder sintering so as to have high density, high seizure resistance and wear resistance. A wear-resistant iron-based sintered composite contact component composed of the wear-resistant iron-based sintered contact material sinter-bonded to a backing metal and its producing method are also provided. To this end, at least CrC-type carbide and/or MC-type carbide which have an average particle diameter of 5 μm or more are precipitately dispersed in an amount of 20 to 50% by volume within an iron-based martensite parent phase which has a hardness of HRC 50 or more even when tempered at up to 600° C.
