“…This is why WC-Co coating has become most widely used coating for protection against sliding wear. This coating can be deposited primarily by thermal spraying [11][12][13][14][15]. However, other methods of deposition such as physical vapor deposition (PVD), chemical vapor deposition (CVD), cathodic arc etc., are also demonstrated [15][16][17].…”

Material degradation due to unidirectional sliding wear can be found in wide range of engineering applications. Depending on the applied load and sliding velocity, several material removal mechanisms will be operative during sliding. Lim and Ashby compile these mechanisms in the form of wear mechanism map. They have also been able to estimate the wear rate in each mechanism quantitatively. However, no effort has hitherto been made to use these expressions and concepts to alter or modify the surfaces of various materials for improved wear performances. The objective of the present work is to address this issue. In this work, the expression for wear rate in various regimes will be examined critically. The important parameters that governs wear rate will be identified. An approach to improve wear rate in each regime will be suggested on the basis of identified parameters. Suggestions will be substantiated with large database and published work.

“…Examinations on the basis of the wear behaviour of Mo and Mo + NiCrBSi thermally sprayed coatings being performed for the application as next generation ring face coatings [6]. Plasma sprayed ceramic coatings portrayed favorable tribological performance at high temperatures [7], showed high wear resistance [8], and were easy to be lubricated owing to the oil storage in pores of coatings [9]. But it is needful to say that plasma sprayed ceramic coatings exhibit some failure mechanisms during sliding such as plastic deformation, brittle fracture, and polish effects [10], which in turn demands a few additives, which could reduce the friction and wear of plasma sprayed ceramic coatings [11].…”

This paper explains the sliding wear performance of red mud, fly ash, and carbon composite coating on mild steel. The complex mixture of red mud, fly ash, and carbon is plasma sprayed at 9 kW operating power level. The coatings are examined to study the coating morphology, XRD phase transformation, wear rate, and wear morphology. Wear rate (in terms of cumulative mass loss) with sliding time has been demonstrated in the study. At first pure red mud is plasma coated to observe the coating characteristics and then compounded with 20% carbon, 30% carbon, and 20% carbon + 30% fly ash, separately by weight and sliding wear test conducted using pin on disc wear tester. The trial was performed at fixed track diameter of 100 mm and at sliding speed of 100 rpm (0.523 m/s) at a load of 30 N. The results are compared. Declined cumulative mass loss by inclusion of fly ash and carbon is seen. This might be due to augmented interfacial tension and dense film build-up at boundary layer.
