Component arrangement, the component arrangement being designed as a shaft-hub connection between a shaft of the component arrangement and a wheel of the component arrangement, the shaft-hub connection being formed by means of a non-positive connection of the shaft to the wheel, the wheel being a sintered component ( 10) made of sintered steel or formed as this, the sintered component being formed by pressing steel powder in a die to form a compression molding and subsequent sintering of the compression molding, characterized in that on a contact surface (12, 17) of the shaft-hub connection a surface structure (13, 18) is formed on the sintered component by means of a laser, the surface structure being formed with pointed material elevations (14) made of martensitic structure (16).
