“…Binary systems show that Cr, Si and B reduce the melting temperature of Ni to 1040 0 C. The result is a relatively low melting temperature of NiCrBSi alloys [10]. After remelting NiCrSi alloys, the published studies [11,12] have contributed to the recognition of the phases of NiCrBSi systems. The base of the NiCrBSi alloy contains a solid solution γ -Ni with a low content of Ni-Ni 3 B eutecticum.…”

“…The Ni-based self-fluxing alloys are particularly suitable for all types of thermal spraying: HVOF [2, 9÷12], flame spraying [2, 7,8,10, 13÷19], plasma spraying [3, 10,11,16], plasma transferred arc welding [5,8,20,21], laser cladding [6,13,15] and arc welding [4,8,22]. So as to obtain the best properties of the sprayed coating, various combinations of the mentioned types of spraying as well as influence of particular alloying elements are investigated in the analysed papers.…”

Original scientific paper In this paper resistance to abrasive wear is studied of the Ni-based self-fluxing alloy coatings deposited by flame spraying with fusion. The "dry sand/rubber wheel" test in accordance with the ASTM G65 norm, specifically B and C procedures is used. The experimental data are statistically processed by using analysis of variance, to investigate the influence of two input variables (type of coating: NiCrBSi, NiBSi; spraying distance: smaller, greater) and their interaction on the output variable (volume loss). Data for investigation were obtained by the full factorial design with two, previously mentioned, factors at two levels with three replications. The analysis of variance of obtained experimental data after 100 revolutions of wheel has shown that type of coating, spraying distance as well as interaction between these factors are significant and affect abrasive wear. At 2000 revolutions of wheel it has been found that the type of coating is a significant factor while the spraying distance, the same as interaction between these factors, is of no significance to abrasive wear. Modeliranje procesa abrazijskog trošenja slojeva na bazi nikla primjenom planiranih pokusaIzvorni znanstveni članak U ovom radu ispitivana je otpornost na abrazijsko trošenje slojeva na bazi Ni, koji su naneseni postupkom plinskog naštrcavanja s utaljivanjem.Korišten je test "suhi pijesak/gumeni kotač" prema normi ASTM G65 i to prema B i C varijanti postupka. Dobiveni eksperimentalni podaci su statistički obrađeni primjenom analize varijance, s ciljem istraživanja utjecaja dvije ulazne varijable (vrsta sloja: NiCrBSi, NiBSi; udaljenost plamenika od uzorka: manja, veća) te njihove interakcije na izlaznu varijablu (gubitak volumena). Podaci za istraživanje dobiveni su faktorskim planom pokusa s dva, prethodno navedena, faktora na dvije razine uz tri ponavljanja. Analizom varijance dobivenih eksperimentalnih podataka nakon 100 okretaja kotača utvrđeno je da su vrsta sloja, udaljenost plamenika od uzorka kao i interakcija između tih faktora značajni te da utječu na abrazijsko trošenje. Kod 2000 okretaja kotača utvrđeno je da je vrsta sloja značajan faktor tj. da promjena vrste sloja utječe na abrazijsko trošenje, dok udaljenost plamenika od uzorka kao i interakcija između tih faktora ne utječe na abrazijsko trošenje.

“…The advantages of flame spray is economical and versatility [3][4][5][6][7]. However, it has some drawbacks such as high porosity, inter-layer oxides and poor adherence [8]. This limitation would be overcome by furnace fused processing.…”

nicr coatings with different contents of La 2 o 3 were produced on carbon steel by flame spray and then furnace fused processing. A field emission gun scanning electron microscope (FegSeM), energy dispersive X-ray (eDX) microanalysis and X-ray diffraction analysis (XRD) were employed to observe the microstructure characteristics of the coatings. The effect of La 2 o 3 on microstructure and mechanical properties of coatings was investigated. The result shows that the addition of La 2 o 3 would refine and purify the microstructure of the coatings, when the addition of La 2 o 3 is about 0.8 wt.%, the coatings obtain the highest hardness.
