This article presents a critical overview of the current failure mechanisms and treatment
methods applied to improve the surface integrity of die tools used in hot forging process. The …

Environmental concerns of greenhouse gases (GHG) effect from fossil commodities and the
fast increase in global energy demand have created awareness on the need to replace …

Carbide coatings provide high resistance to wear and corrosion for their substrates, so they
have recently received much attention from an industrial point of view. One of the successful …

In this study, niobium carbide (NbC) coatings were grown on AISI D3 cold work tool steel via
thermoreactive diffusion (TRD) at 900, 1000 and 1100° C for 2, 4, and 6 h. The …

Mo-Ag-N coatings were prepared by dc magnetron sputtering technique from a Mo target
with embedded Ag pellets, followed by vacuum annealing at 425, 500, and 600° C …

Gray cast iron is commonly used due to its high damping capacity, machinability and low
cost, due to the presence of free graphite and the high fluidity of the molten metal which …

The hardness and adhesion of protective hard coatings to the substrate are the most
important parameters that influence the performance of the tool. Herein, we propose an …

Abstract LiF-NaF-KF (46.5-11.5-42 mol%, FLiNaK) molten salt was used in the thermal
diffusion (TD) process to form chromium carbide coatings on gray cast iron HT250 at 900° C …

NbC coatings were flame sprayed on AISI 304L substrates and further remelted using a 400-
W power ytterbium-doped fiber laser (YLR-500-MM-AC-Y11), inserted into a chamber for …

The production of vanadium and niobium carbides (VC and NbC) layers on AISI 8620, 8640,
and 52100 steels may increase hardness and wear resistance of substrates …
