“…i) Preparation of sample: Base material used for testing of cavitation resistance is made of 16 Cr-5 Ni martensitic stainless steel (MSS)  a material typically used as materials for blades of hydraulic turbines. This material was chosen because of its good mechanical properties and high toughness [11]. Irathane 155, a Polyurethane (PU) material and Irabond UU55/252A adhesive was used for preparing coatings on the substrate.…”

Hydrodynamic cavitation is known to have many harmful effects and of these effects, cavitationinduced erosion and surface pitting are detrimental to the life of hydraulic machines. One approach to reduce material damage could be through development of new materials and coatings with improved cavitation resistance. Though a large body of work exists on surface treatment methods, especially those involving surface hardening processes, use of non-metallic materials such as polymers as coatings on steel substrate has not received adequate attention. Present study addresses this gap through systematic study of different coatings involving vibratory cavitation (ASTM G-32 protocol) as well as studying the dynamics of single bubble near a material surface with appropriate coatings. Mass loss for different coatings under vibratory cavitation as well as the scanning electron microscopy study of these specimens has been reported. Pressure measurement as well as high speed imaging of single bubble collapse near the coated surface is also highlighted to bring out the efficacy of this system.

“…Martensitic stainless steel (MSS), CA6NM (13Cr-4Ni) is one of the cast steel grades, used for hydro-turbine components. Many authors 19,66,105 used CA6NM turbine steel as reference material for comparative studies. To see the influence of operating parameters on the mechanism of erosion, Grewal et al 23 investigated the SE performance of CA6NM at different velocities, impingement angles and slurry concentrations.…”

“…57 Many authors investigated the erosion wear and their analysis was based upon either the signal to noise ratio, L4 orthogonal array, and ANOVA analysis. 14,24,26,27,31,[57][58][59]66,67,[83][84][85][86] SE wear can be considered a non-linear process with respect to operating parameters. Taguchi is a powerful tool for the design of experiment for such investigations with means of modeling and its analysis for finding the effect of governing factors on performance.…”

Slurry erosion usually results in the form of damage to the materials of different components having underwater working domain. Numerous industries have suffered due to this kind of wear resulting in frequent breakdowns demanding repeated financial assistance and poor productivity. Properties and tribo-performance of materials related to distinct slurry applications play a significant role in arresting the slurry erosion wear. Slurry erosion depends on different parameters such as impact velocity, impingement angle, shape and size of erodent, slurry concentration and so on. These parameters differ from one application to another and accordingly, specific materials are selected knowing the extent and severity of slurry erosion wear. In the last decade, many authors studied parametrically the tribo-slurry erosion performance of materials, few of them correlated their investigations to the actual in situ conditions of applications. Various authors have analyzed the effect of operating parameters on the mechanism of erosion and conducted the comparative studies of different materials. Many of the investigators attempted to improve the properties and tribo-slurry erosion performance of materials through surface modification techniques; coating, reinforcement, heat treatment, thermo-mechanical process etc. This review is an effort to covers all such kind of explorations.
