  By the application of the tradicional overhead welding and the different powder coating technologies results a new surface with improved abrasion resistance, we can optimize the dimensions of the part or we can rebuild some surface as a kind of repairing technology. By application of this technology we can avoid the replacement of the total expensive parts of the structure. Opposite to the tradicional overhead welding in this case there will be diffusion connection between the raw material and the surface coating, this connection type shows several positive properites. Our goal is to investigate the abrasion resistance of the coating. In this article we would like to introduce our results of the abrasion test by apllication of different powder coatings.

  Nowadays in the automotive industry both production and service, requires accurate lifetime calculations. Today we have big amount of theoretical background and nowadays the importancy of technical and industrial databases become more and more important. By materials scientific and fracture mechanics aspects are well covered, but the remaining stresses which are present in every step of production, we can not clearly identify the origin of them. There are different paralell methods to mesure them, but the application of different methods are depending on the engineers, and their expreiences at the company. This part of the analysis is not standardised yet, so there are differences even in the same company.
