A bearing apparatus for a driving wheel of a vehicle is provided to promote reduction in the weight and size of the apparatus, suppress excessive stress or wear, and improve the durability. In a bearing apparatus for a driving wheel of a vehicle, a hub wheel(1), a constant velocity universal joint(3), and a double row rolling bearing(2) are assembled as a unit. One(1a) of the inner raceway surfaces in the double row rolling bearing is formed on the outer circumferential surface of the hub wheel, and the other(14a) of the inner raceway surfaces is formed on the outer circumferential surface of an outer joint member(14). The hub wheel and the outer joint member are fitted each other with one end surface(19) being abutted against a shoulder(16) of the outer joint member. The inner circumferential surface at the fitting portion of the hub wheel is formed with a hardened irregular portion(5). The hub wheel and the outer joint member are integrally connected via plastic deformation of the outer joint member with making the hardened irregular portion bite into the outer circumferential surface at the fitting portion of the outer joint member by radially outwardly expanding the fitting portion of the outer joint member. The outer circumferential surface of the outer joint member is formed with a hardened layer at least at a region including the inner raceway surface and a shaft portion(17) except for the fitting portion of the outer joint member.

A ceramic top coat is formed over a heat resistant alloy including Ni as a main component through a bond coat which contains Ni essentially as a main component, Cr, and Al. The alloy for the bond coat can include Si in the range from 0 to 10 wt.%. As a result, in a long time operation, the spalling damage of a ceramic top coat is not easily created and the deterioration of the mechanical properties is small.
