Fig.4 presents the DSC curve of the as-sprayed NiFeBSiNb amorphous coating.The sample exhibits two exothermicpeaks,due to the glass transition.The glass transition temperature Tg,the onset temperature of the first crystallization event Tx,the melting(Tm)and the liquidus(Tl)temperature are marked with arrows in Fig.4.The supercooled liquid regionΔTx(ΔTx=Tx–Tg)and the reduced glass transition temperature Trg(Trg=Tg/Tl)(Table 3) are in accordance with the findings of other researchers[25].The criterion for the glass-forming ability(GFA)γand the critical cooling rate Rc can be evaluated as[32]:
