Investigating the Wear Behavior of Fe-Based Amorphous Coatings under Nanoscratch Tests
The wear behavior of two coatings (Fe49.7Cr18Mn1.9Mo7.4W1.6B15.2C3.8Si2.4 and Fe40Cr23Mo14C15B6Y2) sprayed by high-velocity air fuel technology was investigated through nanoscratch tests under ramping loads. Compared with the substrate, the Fe-based amorphous coatings exhibit lower penetration depth, higher elastic recovery, and lower wear volume, indicating the excellent wear resistance of the...
متن کاملEvaluating abrasive wear of amorphous alloys using nanoscratch technique
The hardness and elastic modulus of several Zr, Pd, Cu, and La-based amorphous alloys were investigated using nanoindentation. Abrasive wear of these alloys was also evaluated and compared using nanoscratch techniques under a ramping load. Damage caused by scratching was examined using SEM. Material pile-up took place in all scratched samples, but to different degrees. The scratched surface was...
متن کاملEvaluation of Microstructure and Wear Behavior of Iron-based Hard - facing Coatings on the Mo40 Steel
Mo40 low-alloy steels are mostly used to produce industrial components such as crane wheels which are exposed to abrasive wear. However, during working conditions, their wear resistance is reduced after a while due to its low hardness. With increasing abrasive wear, the dimensions of components decrease and they need to be repaired for surface modification. In this regard, hard overlay coatings...
متن کاملEffect of Wet and Dry Conditions on Wear Behavior of Amorphous Coating of Fe-Cr-Mo-Nb-C-B
Recently, wear resistant properties of metallic glasses has attracted a lot of interest. Because the surface of metallic glasses are prone to phase transformation, finding the effects of test condition on structure and wear behavior of metallic glasses is important. In this research, by using an automated electrospark deposition (ESD), a layer of Fe51Cr18Mo7B16C4Nb4 was deposited on AISI 316l s...
