چکیده

in industrial applications, most materials are exposed to wear and friction because multiple conditions are used. however, the tribological properties of these materials can be improved with different techniques. one such technique that improves the frictional property of a surface is the use of self-lubricating coatings. in this study, multicomponent coatings of nominal composition cu-ni3al-mos2 have been sputter from the target using the best sputtering condition to get a good morphology and microstructure of the coating. the morphology and micro structure of the coatings were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and energy depressive spectroscopy (eds). the measured microhardness of this coating was 380 hv over 25 g load. tribological properties of cu-ni3al-mos2 coatings were investigated using ball-on-disk (bod) tribometer at atmospheric condition of room temperature. these composite coatings showed a good morphology and adhesion of the coating to the substrate, also it had acceptable friction coefficient and higher wear resistance, because it has hard matrix containing cu-ni3al and mos2 nano particles.

Tribological behavior of sputter-deposited MoSX/Ni coatings

AbstractSputtered MoS2 coatings have been mostly used as a solid lubricant. In this investigation, MoSx/Ni composite coatings with Ni contents varying from 0 to 22 % were deposited onto steel substrate using a DC magnetron sputter process. The MoS2/Ni ratio in the coatings was controlled by sputtering the composite targets. The composition, microstructure, and mechanical properties of the...

Mechanical Properties and Microstructural Evolution of Ta/TaNx Double Layer Thin Films Deposited by Magnetron Sputtering

Crystalline tantalum thin films of about 500nm thickness were deposited on AISI 316L stainless steel substrate using magnetron sputtering. To investigate the nano-mechanical properties of tantalum films, deposition was performed at two temperatures (25°C and 200°C) on TaNx intermediate layer with different N2/Ar flow rate ratio from 0 to 30%. Nano-indentation was performed to obtain the mechani...

Oleophobic optical coating deposited by magnetron PVD

Thin oxinitride films of Zn-Sn-O-N and Si-Al-O-N were deposited on glass by reactive magnetron sputtering at various nitrogen-to-oxygen ratios. Nitrogen added to oxygen led to decrease of the surface roughness and increase of oleophobic properties studied by the oil-drop test. The best oleophobity was obtained for Zn-Sn-O-N oxinitride at Zn:Sn=1:1 and N:O=1:2. Improved oleophobic properties wer...

بررسی خواص پوشش MoS2-Cr ایجاد شده توسط فرایند پراکنش مگنترونی DC

Molybdenum disulfide (MoS2) is one of the most widely used solid lubricants. In this study, MoS2-Cr composite coatings were deposited onto AISI 1045 steel substrates by direct-current magnetron sputtering. The MoS2/Cr ratio in the coatings was controlled by sputtering the composite targets. The coatings were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy di...

Growth of wafer-scale MoS2 monolayer by magnetron sputtering.

The two-dimensional layer of molybdenum disulfide (MoS2) exhibits promising prospects in the applications of optoelectronics and valleytronics. Herein, we report a successful new process for synthesizing wafer-scale MoS2 atomic layers on diverse substrates via magnetron sputtering. Spectroscopic and microscopic results reveal that these synthesized MoS2 layers are highly homogeneous and crystal...
