“…The crater and plastic deformations were also observed on the surface of the pin due to the cyclic surface fatigue fracture. Kazushige 14 and Chiba 15 also investigated and reported the same wear mechanism for Co–Cr–Mo alloy. The constant cyclic action of wear debris allows the contact surface area of the pin to undergo fatigue fracture.…”

In this paper, the sliding wear behaviour of nickel based superalloy pin was investigated on disc with two different coatings. The plasma sprayed NiCr-Cr 2 O 3 coating and Al 2 O 3 þ 40%TiO 2 (A40T) coating were used on the disc for wear studies. The sliding wear tests were performed on dry conditions at room temperature for a constant sliding velocity for two different applied loads (5 and 10 N). The mass loss, wear resistance and coefficient of friction between the pin and disc were studied during investigations. The wear mechanism involved in the NiCr-Cr 2 O 3 coatings is three-body abrasion and Cr 2 O 3 being the third body between pin and disc. The wear rate is high due to the applied load and suppressed cracks. In A40T coating, the minute debris collected on the surface of the coatings acts as a solid lubricant and reduces friction and wear rate. The SEM and energy dispersive spectroscopy analysis were also carried out for characterisation studies on pin after wear studies. The life of nickel pin on A40T coatings is found superior than the NiCr-Cr 2 O 3 coated disc.

“…Kazushige Kumagai et al (2007) [18] investigated the wear behavior of a forged Co-29Cr-6Mo alloy without any Ni and C added by using a tribosystem consisting of a pin-on-disc type wear testing machine in distilled water containing different dissolved oxygen content. Dissolved oxygen content in the distilled water was controlled by aerating with oxygen or by deaerating with argon.…”

Abstract-Researches on the wear of metals have brought new understanding and advanced major concepts of tribology. The availability of new testing methods and instruments have made possible the detailed study of the microstructure, nanostructure, and compositions of contact surfaces. Earlier work was concentrated on the mechanics of solid contact, understanding the true area of contact, asperity plasticity, and transfer during sliding. The scanning electron microscope and the atomic force microscope have provided fascinating insights and detailed information on surface structure. There have also been developments in computational modelling of wear by finite element methods, molecular dynamics, and fracture mechanics. Many wear models and equations in the literature have been developed. No single predictive equation or group of limited equations have been found for general and practical use. Various regimes of mechanical and corrosive wear for any particular pair of rubbing materials can be shown on a single wear map plotted on axes of normalised pressure and sliding velocity. In principle the map can be divided into areas corresponding to different wear regimes, with boundaries of sliding speed and contact pressure beyond which a purely mechanical view of wear would be grossly in error, owing to the effects of oxidation.
