The primary aim of the present investigation is to evaluate the sliding wear response of M50 steel against three different counter-bodies as function of applied load and sliding velocity. The investigation is essentially undertaken to understand the sliding friction of hybrid bearing and ordinary bearing used in spacecraft and aeroengine. Towards that purpose, M 50 steel was made to slide against three different counter-bodies such as M50 steel, 52100 steel and Si 3 N 4 , at three different applied loads and at three different sliding velocities. The results show that the friction coefficient of M50 steel decreases with the applied load and the sliding velocity against all types of counter-bodies. The wear rate of M50 steel against Si 3 N 4 counter-body increases with the applied load and the sliding velocity. In contrast, the wear rate is generally independent of the applied load and the sliding velocity against 52100 steel and under self-mating condition.

“…In contrast, TiCrN coating exhibits significantly lower steady state friction coefficient which is around 0.6. The friction coefficient of TiCrN coating is low due to lubricious properties of Cr 2 O 3 scale 22 that forms during sliding 10 . The friction coefficient of the substrate is in between these two values.…”

“…The reason for this is formation of Al 2 O 3 scale which has very high hardness 24 . Scale forms because of high flash temperature generated at the contact point 10 . Thus, it can be stated that all coating are promising coating for application requiring wear resistance.…”

Present study examined the microstructural features, hardness and wear performance of TiAlN, TiCrN and n-TiAlN/α-Si3N4 coatings deposited by cathodic arc physical vapour deposition (CA-PVD) technique on M-50 steel keeping in mind a possible application of hybrid bearings in next generation aero-engine. Microstructural features of the coatings were evaluated using scanning electron microscopy (SEM) and transmission electron microscopy. Hardness was measured using microhardness tester. Wear test was carried out with the help of ‘Bruker’ tribometer. Worn surfaces were characterised employing SEM. Results show that TiCrN coating has crystalline columnar structure and other coatings have nano-crystalline structures. Besides improved hardness, TiAlN has best wear resistance and TiCrN coating exhibits least friction coefficient.

“…As one more addition to this, in one of the earlier research works, the expression for wear rate in various regimes was examined critically. The important parameters that governed wear rate were identified and an approach to improve wear rate in each regime was suggested on the basis of identified parameters [14]. Recently wear mechanism maps were developed for high temperature applications for boron steel metals and these maps were also used for the study of wear behavior of boron steels under various loading conditions [15].…”

The previous research investigations informed that the tool wear of any machining operation could be minimized by controlling the machining factors such as speed, feed, geometry, and type of cutting tool. Hence the present research paper aims at controlling the process parameters to minimize the drill tool wear, during the machining of Glass Fiber Reinforced Polymer (GFRP) composites. Experiments were carried out to find the tool wear rate and a wear mechanism map of uncoated High Speed Steel (HSS) drill of 10 mm diameter was developed for the drilling of GFRP composite laminates. The surface micrograph images on the drill land surface displayed dominant wear mechanisms induced on HSS drill during machining of GFRP and they were found to be adhesive wear, adhesive and abrasive wear, abrasive wear, and diffusion and fatigue wear. A “safety wear zone” was identified on the wear mechanism map, where the minimum tool wear of the HSS drill occurs. From the safety zone boundaries, it was inferred that the drill spindle speed should be set between 1200 and 1590 rpm and feed rate must be set within a range of 0.10–0.16 mm/rev for GFRP work and HSS tool combination to enhance the service life of 10 mm HSS drills and to minimize the tool wear.
