Comparison of abrasion resistance of boron - and vanadium-based coatings

This research focuses on testing of abrasion resistance of boron- and vanadium-based coatings. Coating of sampleswith vanadium was completed by classic and duplex procedure with previous carburization. The samples were abraded by applying the ASTM G65-94 method of „dry sand/rubber wheel“. The greatest wear was recorded on boron- based coating, and the least wear was exhibited by the vanadium-based coating with previous carburization. The dominant form of „zero“ abrasion was determined by analyzing the sample wear traces.
