“…Therefore, hardness was also influenced by the amount of solid solution alloying on Ni-FCC dendrites, as previously reported by literature [9][10][11]15 . Aiming to identify the influence of PTA deposition current and substrate on coatings response to abrasive sliding wear, coatings were tested in the as-deposited condition with a constant set of testing parameters.…”

“…Rolling cladding is largely utilized to produce coated steel sheet components attending different corrosion requirements. Additionally, welding processes like plasma transferred Arc (PTA) have been studied as an alternative due to the high quality of deposits 3,[11][12][13] . When a welding process is involved, the effect of substrate and the degree of interaction due to processing parameters (measured by dilution) has to be taken into account 14,15 .…”

This work assessed Ni-based C276 alloy coatings by PTA with different degree of interaction with AISI 316L and API 5L X70 steel substrates. Track geometry, dilution and microstructure of coatings were evaluated by optical, scanning electron microscopy and X-ray diffraction. Properties were evaluated by hardness and wear tests. Microstructure exhibited austenite Ni-FCC dendrites and interdendrictic regions containing carbides. Dilution from 4,9 to 25,4% for coatings on API 5L X70 leaded to hardness ranging from 283 to 243 HV 0,5 . Otherwise, dilution between 22,3 and 41,5% for coatings on AISI 316L induced hardness from 267 to 225 HV 0,5 . Higher interaction with the substrate leaded to 19,8% increase of mass loss rate on API 5L X70 coatings. The slight difference for coatings properties deposited on different substrates indicated that the degree of interaction was the most significant factor.

“…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.
