| description.abstract | In recent times, MoSx or MoSx-based composite solid
lubricant coatings have demonstrated some potential in
environment-friendly dry machining. However, most of the previous
studies were restricted to drilling and milling operations. In the
current research work, MoSx-Ti coating with TiN underlayer was
deposited using pulsed DC closed-field unbalanced magnetron
sputtering (CFUBMS) technique. The deposited film was
characterised using field emission scanning electron microscopy
(FESEM), grazing incidence X-ray diffraction (GIXRD), scratch
adhesion test and Vickers microhardness test. The performance test
of the coating was carried out in dry turning of ISO AlSiMg
aluminium alloy and IS 80C6 high carbon steel with uncoated and
MoSx-Ti (with TiN underlayer) coated cemented carbide inserts.
Results indicated that coated tool arrested the tendency of formation
of built-up material during machining of aluminium alloy resulting
in superior workpiece surface finish compared to that for uncoated
tool. During dry turning of high carbon steel, the same coated tool
resulted in reduction in axial cutting force in the entire range of
cutting velocities (32 to 230 m/min). During machining at higher
cutting velocity the same coating provided effective diffusion barrier
by restricting crater wear. | en |
