Tehnologija reparaturnog navarivanja noževa pluga za čišćenje snega

Abstract

Possibilities for reparatory hard facing of the working parts of the snow plough are analyzed in this paper. The snow plough blades can be considered as working parts of the construction machinery, which during exploitation are exposed to simultaneous action of abrasive wear, corrosion and occasional impact loads of high intensity. During the snow removing those parts come to direct contact with hard road surface, while the highest intensity of wear occurs when the snow is being removed from the asphalt or concrete roads, since then they are in direct contact with rock minerals which are the constituents of asphalt or concrete. The objective of this paper was to investigate the possibility for reparation of the damaged blades and to propose the hard facing technology. The proposed technology was tested in tribological conditions on models and on the real working parts and it was proven as very successful.
