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 th...
