High temperature friction and wear behavior of MoS2/Nb coating in ambient air

MoS 2 coatings are well-known for their solid lubricant properties and used as self-lubricants in vacuum and inert gas environments, and such coatings are not used in atmospheric conditions because of their deteriorating tribology. The tribological performance of MoS 2 solid lubricant coatings in the different atmospheres has been improved by the codeposition of a small amount of another metal. In this study, the tribological behavior of MoS 2 /Nb coatings was investigated in ambient air at temperatures up to 500°C by using high-temperature pin-ondisc tribo testers and alumina balls as counterfaces. MoS 2 /Nb coatings were deposited on silicon wafers and AISI 52100 steel substrate by closed-field unbalanced magnetron sputtering. The structural analyses of the coatings were performed using X-ray diffraction and scanning electron microscopy techniques. The hardness was measured using a microhardness tester.

“…Blistering can be prevented by co-depositing MoS 2 with a metal [19], which affects not only friction coefficients but lead to higher hardness values and lower wear resistance, not only in the presence of oxygen, but also in high humidity [18]. However the hardness, wear resistance and the lifetime of a coating in a humid environment has yet to be resolved [20].…”

Hybrid Ti-MoS2 Coatings for Dry Machining of Aluminium Alloys

Combinatorial deposition, comprising filtered cathodic vacuum arc (FCVA) and physical vapor deposition (PVD) magnetron sputtering is employed to deposit molybdenum disulphide (MoS 2 ) and titanium (Ti) thin films onto TiB 2 -coated tool inserts specifically designed for the dry machining of aluminium alloys. Titanium is deposited by FCVA while MoS 2 is magnetron sputtered. The deposition set up allows several compositions of Ti-MoS 2 to be deposited simultaneously, with Ti content ranging between 5 and 96 at. %, and their machining performances to be evaluated. Milling took place using a CNC Vertical Machining Center at a 877 mm/min feed rate. The effect of different coating compositional ratios on the degree of aluminium sticking when a milling insert is used to face mill an Al alloy (SAE 6061) was investigated using a combination of energy-dispersive X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS) analysis. XPS studies suggest that the greater degree of Al sticking on the rake face of the inserts is due to the formation of greater amounts of non-protective Ti-O phases. EDX mapping of the milling inserts after machining reveal that a Ti:MoS 2 ratio of around 0.39 prevents Al from sticking to the tool edges. Since we prevent Al from sticking to the tool surface, the resultant machined surface finish is improved thus validating the machining performance of TiB 2 -coated tools using optimum compositions of Ti:MoS 2 thin film coatings.

“…These coatings are developed using a multilayer, hard/soft, or composite architecture. Examples of the added metals or ceramics are as follows: gold (Au), [20] titanium (Ti), [21,22] chromium (Cr), [23,24] chromium nitride (CrN), [25] titanium nitride (TiN), [26][27][28][29][30] or titanium diboride (TiB 2 ). [31] MoS 2 /Ti composite coatings (MoST) have been widely researched and are already widely used in the industry to improve the performance of metal forming tools.…”

Influence of the Composition on the Properties of (Cr_1–xAl_x)N/Mo_yS_z PVD Coatings

Cr 1Àx Al x )N/Mo y S z coatings promise a solution for replacement of lubricants on highly forced tools in dry cold forging. Wear resistant (Cr 1Àx Al x )N together with the self-lubricating Mo y S z deposited using PVD technology offers an extension of tool life without lubricants. This combination is insufficiently researched and its capabilities are yet unknown. In this contribution, (Cr 1Àx Al x )N/Mo y S z coatings are deposited by means of PVD in an industrial-scale unit. Decreasing the Cr and Al content by increasing Mo and S content, influences the coating properties considerably. It is found that hardness and indentation modulus decrease. However, an increase of the deposition rate is observed. A reduction of the friction coefficient with the increase of MoyS z content is detected.
