摘要：
The paper presents both material and technological concepts of coatings containing selected borides (FeB, CrB2, (TiCr)B2) and carbides (B4C, B4C-CrB). The selected borides and powder compositions were prepared by diffusion synthesis (chemically) and then were electrolytically covered with a nickel layer. The plasma spray parameters were determined. X-ray analysis was carried out to investigate the chemical compositions of the coatings. From the X-ray analysis results, we determined the phase transformations in the coatings after plasma spraying. Both the wear and erosion resistances of the coatings obtained were determined and compared with those of WC-Co, NiCrSiB and 45 VFNS (Metco) coatings. The results obtained in the tribological tests were applied to a selection of highly wear-resistant boride coatings.
