PCT No. PCT/SE94/00920 Sec. 371 Date Apr. 4, 1996 Sec. 102(e) Date Apr. 4, 1996 PCT Filed Oct. 4, 1994 PCT Pub. No. WO95/09736 PCT Pub. Date Apr. 13, 1995The present invention relates to a device for improving the adhesitivity of surface refined parts (6) to the body (7) of railway wheels (1), which surface refined parts (6) have been produced by treating the railway wheel (1) with high energy generated preferably by laser radiation (8). In order to prevent or at least obstruct the risk for loosening of the surface refined parts (6) from the body (7) of the railway wheel (1), the maximum thickness (B) of the surface refined parts (6) is selected so that the Hertzian pressure which affects the railway wheel (1) when said wheel is loaded with the maximum permitted pressure thereon is substantially carried by the body (7) of the railway wheel (1) beneath the surface refined parts (6).
