The corrosion behaviour of both crystalline and largely amorphous forms of the Fe-based glass forming alloy, Fe 43 Cr 16 Mo 16 C 15 B 10 alloy was investigated. Two different methods were used to induce transformation to the amorphous form of the alloy: laser melting and HVOF spraying. Both methods produced largely amorphous material, however the high brittleness of the alloy makes it susceptible to cracking during laser treatment, hence this technique is not suitable for largescale application. Potentiodynamic scanning showed that in 0.5M H 2 SO 4 and 3.5% NaCl electrolytes both amorphous forms of the alloy had better corrosion resistance (lower current densities for -200 to +1000mV SCE) compared to the crystalline material. The laser treated material and HVOF coating performed similarly in 3.5% NaCl. In 0.5M H 2 SO 4 the HVOF coating had a lower current density than the laser melted material for almost all of the potential range -300 to +1000mV SCE. The improved corrosion behaviour of the largely amorphous material is attributed to its homogeneity, and particularly to the elimination of the Mo-rich phase that underwent preferential corrosion in the crystalline form of the material.

“…Therefore, the 5s electron from Mo would transfer more easily than those from B, leading to strong s-d hybrid bonding nature. Moreover, the large mixing entropy of −51 kJ/mol between Tb and B is also beneficial to a very strong bonding strength [35]. So the alloy system exhibits large compressive strength and hardness (H v ), and both f and H v increase with increase of Tb content.…”

“…Recently, Li et al reported that Dy element with relatively high bulk modulus (41 GPa) has positive effect in the development of BMGs [21]. Similarly, it was found that the addition of transition metal like Mo can simultaneously increase GFA, thermal stability and fracture strength in Fe-based BMGs [22,23]. Our previous studies showed that (Fe 72 Mo 4 B 24 ) 94 Dy 6 BMGs have good GFA, magnetic and mechanical properties [24].…”
